# WWDC2000 Session 155

## Transcript

Kind: captions Language: en I'm not go ahead hmm try that point you already wondering thick accent we're going to keep me awake talking about text so maybe that will change your mind text on Mac OS actually I prefer this one real sex on necklace so welcome to session 155 real text on record we'll be talking today about the technologies that will enable you to handle unicode text on Mac OS 10 mac OS 9 next version of 9 and of course carbon level will be talking of course about advanced typography on the new system will be talking to about MLK the mutant enjoy texting Jonah all right whatever platform you're developing for Coco carbon or classic when I say actually carbon I talk about carbon lib and Mac OS dinner or rather you need to handle text or most applications do behind my mind to way to handle this there is the hard way and there is the easy way the hardware your application is very fine control and very fine tuning of the style where the police are going to be positioned on the screen and these are like you know the steps that you have to Latinos follow in order to handle text you have to do text input it could be raking up a different settings but like character set conversion if you want to endure io select you know from different encoding files that are coming from the net to gsh further the coming from windows text manipulation and text layout we're ordering of the round six you doing Latino boutique script text and of course the rendering and there is the easy way the easy way will be to use like one of several texts packages and the text packages will actually use one of several layers well there let's see the text edition that we have right now for mac OS 10 and classic applications so once again the different technologies I'm going to be talking about are available online carbon lip and os then of course here again i will divide back in to settings would be what i call the pre unicode and i'm sure if you have been using one of these technologies text input where you could do it with like you know the event record where you get a key down or you could be using TSM tech services manager if you need to enter two bites the character set to engine conversion sorry has been used as been used by ki see the text encoding converter I'm sure you've heard about that tech manipulation the script manager with text layout and the rendering as your no creo text and quick draw since 8.5 will be introducing technologies so developers can enter unicode easily these technologies of course available on the coast and text input if you want to do unicode input there is only one way and this is to install the gsm handlers card just and conversion of course you still have to use TC text manipulation in order to do unicode line breaks sorting for instance you use the unicode utilities the text layout should be using at three apple type services for you Nicole imaging which is the only way to do unicode layout correctly the rendering quick draw and of course moving towards Latino new technologies corp which you're watching on 10 before we go in details and we talk about each of these technologies I like just to let you know to get forgot about this one sorry for the easy way the text packages you'll be using text edit sure we heard about this technology and of course for unicode MLT the multilingual text engine introduced on mac OS 9 a volleyball on carbon lip and on 10 so before we talk about these technologies like just to make a quick reminder why unicode is important unicode is an interest in industry and internet sound or even windows uses it and no unicode is not a monopolar it's the only way to win the new languages there is no more room in worse scrapes to handle more languages unicode is the solution if you want to enter the new extension for a big five points and hong kong extension handle latino of extended character sets for Roman or Latino access the new trees that have been defying the gsx 213 standard the only way to do that is to use actually and to encode you the documents in unicode i'll give you a quick example right now for the characters are just appear this car shows a part of extended Roman character set right now if you click your text the only way to render these characters use five different encoding but means if your applications want to burn in Hungary you need to fight like you know a different sound than the one that is sitting on the US system but means to support its characters need five different phones with Unicode only one front and i'll show you back in the demo is sufficient and the phone tech Geneva for instance is already set up for that before we go to the demo I'd like to introduce Deborah Goldsmith who will be talking about the different drug technologies there is a manager of international toolbox which owns the three technology thanks actually so Dhabi I talked a little bit about the system components that an application can use to support Unicode and I'd like to talk about those in a little bit more detail to put them in context here's a diagram of the flow of data in a Unicode application first of all you have information coming into the program either coming from the network or disk possibly the internet if it's in a legacy encoding you need to use P ec to convert it into unicode if it's coming from the keyboard or some other input device use TSM the text services manager to process the input and make it available to the application after your application has done its processing use up to e apple type services for unicode imaging to lay out and prepare the text for display and then finally you can use quick draw or courts on mac OS 10 to display the characters now i'm going to talk about each of the technologies in a little bit more detail first of all the text services manager which has been in Mac OS for quite a while since 71 at least I think it was their first for support of asian languages but over time it's been taking on more and more functions right now it is the only way to receive unicode input and you application so it's necessary if you want to get unicode directly from input sources as i already mentioned it supports input of asian languages that require input methods but it also supports other kinds of tech services examples include spelling checkers hyphenation and even speech recognition and starting in mac OS 8.5 TSM added support for one byte languages as well as the double by asian script new with mac OS 10 in carbon law TSM now supports the carbon event model so you can continue to receive input from TSM using apple events as you have in the past or you can now use the carbon event model instead and TSM also takes care of matching up Unicode and non-unicode applications with Unicode and non-unicode input sources so your application doesn't have to worry about whether a particular keyboard or input method produces Unicode or legacy character set outputs TSM will take care of converting it for you into the form you need the text encoding converter is another important component there's a problem the internet the mac OS and windows all use different character sets and not only that each of them has many many different character sets all of these character sets are different and encode characters in a different way and if you just try to use data that's in one character set and assume it's a different character set you're going to get garbage the solution is the text encoding converter which has been available in mac OS and say point one TC will convert between many different character sets and Unicode as well we've spent a great deal of time working on Tec in order to make sure that when it's converting from one character set to another that it preserves as much of your data as it possibly can and if there isn't an exact match between two different character sets p ec will try to find the best possible representation and we think it has the best conversion accuracy in the computer industry Tec seems to have been very popular it's used by many different applications including Microsoft Office Internet Explorer and outlook express Eudora power mail and many more the Unicode utilities were new in mac OS 8.6 and were extended in mac OS 9 they're equivalent to the international text utilities and the script manager which has been in the mac OS for a long time but there the equivalent versions for Unicode text they support operations like collation namely comparison and ordering or sorting of text in human languages they support text breaking finding boundaries between texts units like words lines or even clusters of characters in addition they provide access to information about characters such as whether they're left to right or right to left or upper or lower case and these come from the unicode 3 point out character properties database and finally unlike the script manager in international utilities which use the model of a script code and a region code which are unique to the Macintosh the Unicode utilities use a new locale model which is very similar to the way that java and unix systems handle international processing actually your apple type services for unicode imaging is our solution for drawing unicode text it was introduced in mac OS 8.5 and we've been extending it and improving it with each new release and we continue to do that actually is the only solution on the mac OS for direct imaging of unicode that is handling all of the unicode standards not just small pieces of it it provides a larger character and language repertoire covering new languages that you can't do any other way plus parts of existing languages that are hard to get to using quick draw so the example you see on the screen has tied Vietnamese Greek and a few other characters I'll describe in a moment the first part of the example is all from the lucid a font that's part of Mac OS 10 that's all in one font handling a Vietnamese and Greek as well as Roman of course the characters at the end our characters that are in The Times font which has been shipping on the Mac OS for many years but those characters can't be gotten to through quick draw their characters that are in Unicode and in the windows character set but not in the Mac character set so even though they're in the font there's no way to get to them many times I get emails from people using Windows systems and they have characters like this in them and it's not possible to display them except now with Unicode and actually actually also supports the full Unicode bi-directional model which is very complicated supporting languages like Hebrew and Arabic and four languages like Arabic and indic languages like devanagari actually supports complex rendering of text actually has other features besides access to more languages for example for Asian text in quick draw double by text is required to have all the same width for every character so every kanji Arcana in Japanese for example has to be the exact same with with absolutely you can have proportional double by text different glyphs can be different widths in addition actually supports something we've had many requests for from our age and developers namely vertical text the same features of XV which support complex scripts like Arabic or tie or devanagari also support advanced typography for Roman languages so you can get advanced typographic effects so we haven't been sitting still with us we've been adding new features and new for Mac OS 10 our API for accessing the outlines of glyphs and glyph metrics and this is specifically meant for applications that have used ATM to do this in the past since ATM is not available on Mac OS 10 in the future we plan to do much more to actually we're working on it very actively the first thing we're going to do is lessen its reliance on Apple layout tables so right now to do the advanced type of graphic effects or certain kinds of language support you have to have apple advanced typography tables and your font we're going to continue to support those because we think they handle those functions very well but we want to make actually work better with more different kinds of funds so the first thing we're going to do is make it able to do advanced layout and language support using fonts that have no layout tables at all because that's what most of the funds out there have no layout tables at all in addition there are more and more opentype fonts coming on to the market and we want to support those as well and take advantage of the layout tables and those fonts so that's something we're going to be working on for future versions of absolutely also in addition there are many developers such as those working on high-end page layout applications who need very fine control over the layout process and the positioning of the glyphs in their applications and we are going to be adding a low level layout API to absolutely which will give those developers the control they need and those are all coming in future releases and weren't working on them right now so now I'm going to turn the stage back over to za PA so he can talk about the multilingual text engine thank you there you are thanks a lot all right the mechanical text angina so as they were described this is how your unica deprecation will look right now if you are to use these technologies what MIT is going to do for you is going to try to shield you from the complexity of dealing with like you know all these technologies it's a unicode text engine and let's see what is exactly energy energy the replacement for texted it and that's important so that it's a replacement for text that it I said it twice a complete unicode text back edge and when I second technical text package because we do unicorn put unicode layout and unique display we don't lose information during the process of rendering the text from the input to the rendering it's easy to adapt and we have simple code actually for like you know proving that and i encourage you we have like some documentation slide to show like to see like you know the network's project that we have it's one set of CP eyes and supported on three different environments on my quest and of course nine and carbon liver but ten nine and carbon liebe so that means you can come back go back to nigeria and start aquino checking out the demo but we are you can start coding online just to find out if actually this is correct this is a good technology for your application and one you use vp is the same API is are going to work on carbon lib and then on ten transparency okay getting confused it's written in English provide my elect invite on stage John Harry Joyner is vertically the forum LT been working on a Mickey for a couple of years now and we show you exactly what MIT can do for you from a graphical point of view and from a legal point of view all right so this is DP for with couple of an instant this application is apollyon you'll find it in the system demo folder it's using right now click dro rendering an s3 for like Virginia Code layout here when you create a new document what's happening that you get this default window okay at that point MLP created with one call the handlers of a drag and drop the Hendra for TSM for your application can enter two by Scripps so now you have to spend time in studying the TSM handlers we get them fired by default the scroll bar we handle like you know active scoring as well so this is important to notice this is one code txn new object and there's going to do all these things for you all right so there's my little cheat sheet here a big difference we've like what you used to for instance if you simple text or like the creature quick cortex that here the Fox menu is organized by phone family and here for instance an instance i create korea is like both volatile okocha different representation of this form so here the font menu is created automatically by MLT it's once again one API you pass the menu handle and we're gonna build up the hierarchical font menu for you something new if you that Sue is that phones now have like we're more information so not only you know the Unicode information with their as well advanced typographic features and you have to set of features you have first ones that are represented here and your phone variations so here fault XP are for instance as like different representation for like the glyphs this representation are formulated by the phone designer the phone designer decided well I'm going to do an instant of a skia phone that's going to be represented light or extended or bold super bored so here once again at that point your application calls one API and MNT the text engine is going to handle for you what the current selection change change vertex do the reflow free flow is needed we do the brake line let's see now why did I code is important and by disorder when you're going to use the MLT you get like all rights we support and all the unicode support so here we have a vietnamese phylum diciendo misfire is included in munich odom in this case it access a lot of the characters are in textedit drummond character set this file cannot be rendered with quick Joe Tex for the very simple reason that most of this character cannot be included if you use a mac OS room and character set so for instance on the right of the screen we have like simple texture here we're going to try to drag and drop part of the text to simple text and what could we see at that point so first what happened in your application you gotta click you send the click event to TX and click at that point nht is going to enter the race we're going to find out it's a drag and drop we're going to explore different flavors to the drag manager for the drag manager and over application can understand it and in this case what we did is that we exported from unicode and blood three style to something that simple tests can understand which is mac OS Roman texts proof that information and here we can see that you know during the transition will CC of code as good TC reason you cannot render a certain character so you can see for instance on the second line n a TC has been sufficiently clever to find out that in fact it could decompose the Unicode character in to mac OS Roman characters but then of course after the M you can see that this glyph doesn't exist and cannot be rendered with credo text so we place it here with a question mark so what's the source here that we're using this is busy diagram there from that using a mac OS 10 and this boat has like you know all the extended character sets for ramen plus many other glyphs on and we can / during the Q&A if you want after so we access the romantic extended character set which is good but one thing important for customers to in of Japan market is like all these extensions to for instance big thigh and the new geez x2 13 have been talking about using Unicode and using at three and of course when you the mid kids transparent for you give you access to this nigg lifson and here for instance them the three first maguro the first three lines are can be rendered with osaka dos equis aunt has this clip but we can see that the beliefs after cannot be rendered they're just not present in osaka zone and here the thought is oregano which is a new font introduced on the kurdistan and this is the only way you can access this form there is no other way to do that so it didn't talk about the last two lines actually the last two lines of variance of the glyphs represent data in the gsx 2113 standard and the way to access the place actually is that it's just buy some variations and I'll show you why violations are so important features are so important when you distend when you lay out sex down so when using Mickey you can access all the power of h3 and all the power of using Unicode imaging but a nice thing to in using these technologies are the advanced echo graphic features and it is just the wave a text is rendered right now if you go in simple text you take a contact chancery change the size make it a little bit bigger and you type some text this is how it's going to look okay so this is the default behavior and you know you tap the are this is the default or everybody is going to get the same glyph if you copy this text and now we put it in shop volume then you get a nice long squash on the r to the e you get the key know when you get your goes back to the AVL at the end line / and this is the default that you get but then because we do like you know the layout and Atsui processes with texture you get this behavior and I think the text is rendered like you know pretty nicely so we can change the size make it bigger smaller of course and you can go Adam in that's nice [Applause] alright so here on the toilet on the riser you get the usual style so you can select X type some text and as I said now when you're going to be using a messy and because we're using at three we can access all this advanced typography features things that before you could an excess just because we didn't have the api's and that we do text is too limited to do so so here we take like you know we type some text you can see that during the time a drum is typing the text is changing because for instance here the earth is going to change the ligature on the eight is going to move lizard which means the eggs in French are you see the earth changing if you know a little bit of French you know but earth is not written like that in fact there is a distance between the oh and Zoey so how you going to do that so as I said on each phone but Apple has been shipping in the last I don't know many years as a setting of teacher so here what's happening is that shop or you get the current direction from MLT and as to the phone give me the list of all the features that you have and here we are so we have a bunch of topographic features dedicate diacritics vertical position fraction ornaments all these themes of studying the salt so here for instance we can turn on the gift on and hope the letter changes the text is the same we didn't change what store of sex it's just the way the layout is processed now we have a distant set up so I'd sweet very clever to know that the owner yes to be combined so we have of course texting but our liking us washes rarely get root and you can see the nice compartment the s going from to the to the e this is if you'd imagine you application are going to be able to render text like never have been able to do before and it's like you know you have all the power of Unicode you're going to be able to access the two by Scripps voice focusing on how difficult it is to handle this and you're going to be accessing all this feature so another nice feature that we have it sounds like is Kia for instance has been shipping for several years now as like violations inside so if we type some text on and we bring back the typographic features shop for you is going to be asking to the phone to the skiers on give me all the by actions that are storing in the phone and here at that point if we click on variations we have features as well so here just a click on the letter K as we change everything to cut and what is important here is that the text didn't change is just the rendering okay if we select this text and put it in simple text for instance you still have the original text in the keynote small cups and the variation so here he has to type of variations wait and wait and you can see that you know just in real time you can change the way the text is gonna flow you can change the way and you can change the width on so it's kind of important for like you know if doing like you know layout document formatting it's very nice it's like you know your kid what to create some relax and lex pliers you know things for like it's cool you can do a couple of bunch of things so where you get your play with it you know it's in the system demo shop for you you can play you can try with the phones by a bunch of phones that are shipping with my question DP for and play with it to see you have different compartments I mean I think it's going to give you an idea of like watch the technology is about and how you can implement that is new application all right so ma ki gives you access to unicode gives you access to advanced topographic features but as i said to it's a replacement for text edit and people have been asking of course for like many features to add to texted it in this case most of these things are in shop alone so one important thing is invalid objects MLT support embedded objects and it's transparent and if you have been creating simple text files with misfiled and you want it to put a pictures you know annoying it is to create the resource-based 10,000 and put the embedded characters here in the data for call the texture and then of course if you want to satisfy to Japan you have to change it because what's happening is that the see a character is the first bite of the to buy character so you have to change everything again here with one format when you're going to save energy you get pictures sound movies text unico text the features the ligature or the phone valuation and here we just have a movie and we can play you can ship back to your customer so with a new releases wedding like two types for saving this movies which i think you give interested because if the movie is 50 megabyte well if you flatten the movie to the disk when you save your file you're going to get like a file of 50 megs on so a new way to do that is back you know to just set up the reference and that's nice because you can be creating your document you could ship it to your customer and inside you could put a movie that is in fact somewhere on your network so it could be just going like on the internet and aquino loading the file and screaming it so we can see you can save that in your document you can type texts of course here if we open a picture we get a big picture we let's try to get that you know just a piece of it so we're going to copy that so here applications and owning it you passed it in the documents at that point once again one curl txn pays the x10 place is going to check what's in the current scrub board if it's the picture we're going to handle it for you if it's a movie we'll test it if it's takes them with sky resource when you know like you know the West Central Texas think we're going to pass this in the document it's one call for you and here at that point drag and drop something you get a click in your application you pass the click to the checks and object and we're gonna endure if you are scrolling if the click is in the scroll bar we're going to enter it to the beginning of the drag and drop so I think it's pretty powerful before we go to the next in my first slide or maybe the second side I was saying that you know what technologies on 10 are moving forward and now we're trying to implement and using of course like you know all the power of Mac OS 10 and what one of the very nice features of micro strain of course is squats rendering so what I'm going to show you is just something or working on a case not finished but here we're going to be using an LT and when we release this will be using by default quads and your application will see nothing it's just like sitting attack and you'd be switching from quick George Cross rendering so here we have a document with a special version of shop early on and here we can see we can change the key no this is only like you know quad rendering so like what's happening at that point is like you know with triggering a CD context and here we just changing the way the shadow is going to look so we can change the right hands like you know for a shadow we can change the K which is like the coefficient for the transparency of the shadow so here at school we cannot see it so let's trying to change the height so here we change the height you can see the shadow getting away at that point fitting these kind of features is the standard setting of variation it's just once that it's like another strategy which working on you can change the angle so look at that you love angle can we change the coefficient for like the relations like darker and here we can move the shadowrun the texture we can put it like you know far away and here of course if you type texture you can just type and that's it we're reducing quad at that point you get all the night shadow in the next leg behind that so this is coming soon that's fine thank you alright thanks let me go back to my slides now so once again check it out the version that is in vp for system demoed the application is called Jean polio I think the movie supports not enabled in this specific release but you know it's just coming soon you can play with the phones check out see our text entries where earth float x is there you have a bunch of features you can play with that what can I make it do for you so msg is going to be ending the unicode input redditing on the display as a complete package so for instance if you want to do like you know to bite input you're not going to insult gsm enter once again this is created automatically when you create a new TX an object an MLG object it addresses many text edit limitations and other slides on the feature to show you actually like you know a set of features that we support it enters the low-level my address transparently so once again same thing when you create a GX a new object we're going to install the dragon blur we're going to install the scroller if you want to original score boys just as a flag that you pass to the object you want the vertical scroll bar it's another flag oh this thing is going very fast for me which makes adoption very easy and we have sample code once again to show you that it provides easy access to as to advance topographic features sitting at sweta programming features with an LG it's just a matter of setting a stylus abuse it's like setting balls like setting italic all right let's see what every feature last year when I did actually if I talked to a couple of developers and every time you ask them what is the feature that you really need it in a text and giant what if you work to change something yes do 42 killing it I think this is on a timer sorry about that so if you asked to develop I would say that you know no 32k limit and energy of course handles more than 32 k text so you don't have to worry about that the size limitation is only limited to the memory of your application so this is great tabulation support you can now set to start setting for document so you know note icon texted it when you press tab well when you press tab we're gonna have a real tabulation you're not going to space so I'm going to like you know go fast embedded objects with report picture sounds and movies and once again the way to set that is just a matter of like you know one API a handle on the data Wow the handle on the data and that's it you said we keep our own do switch report 32 levels of undo and widows once again just a matter of simple API txn undo GX and we do we support setting for fuji specification support it's one sitting for document well getting pretty button workin sure if i have time weak links calling as i showed in the demo the printing and the clipboard support is done for you we have api's to handle button and if you moving to carbon and 210 for instance you know that you know you have to revise the printing and here with you if you use a milky that would be handled transparently the i/o we introduced a new file format txt mm which is the file format that's going to save that will be safe to be different let's go to support the embedded objects that you will have in your document the Unicode text and all the h3 style attributes so the features of violations and all these things but you can still save of course if you desire if you want to do so a plain unicode file and will do it automatically for you jegs and save you pass a net expect and a flag with the type what you want to save to and which report of course the simple text format so when used a mail key you can see the export data so simple text appleworks microsoft word can understand there are two ways to use energy and the first one is like for text editing you'll be using it for level most texted each field of Molly deter and the second way and we've been adding that because last year we talk to developers and there is one sick the one seed is static display of unicode sex they want one API where we're going to be able to pass a Unicode string and maybe some parameters erect and that state and is going to be displayed and this is VI to use in this case and I talked about that my next slide we have one API now it takes two flavors if you're working on car beneath them you can pass a sphere string or if you're working online you can still pass that you know a unique a pointer and a length there and it takes many options by default you just need to pass the text and the rectangle but if you want you can pass many more and I'll show you that in the next slide the text editing videos for sno tek de tareas on texting it does a lot of things for you with very few calls it report all that sweet style and tags and this is important if you see the earth my garden and this is important because i still give you access to like you know a range of new style and features but you know you couldn't access before so energy with one simple API is going to give you access to all these things it's easy to state and retrieve line word characters from the document once again now you can call an API and get a king of the fifth word on the second line just that it takes care of in line text input the layout and the rendering once again when you initialize the text and shine we're going to install a bunch of Hendra for you and we're going to try to make your life really easy so you can focus on what your application is supposed to do and not the way we should handle text msg is going to handle that for you the tactic before Amenti just as a quick example if you wanted to ender to bite script before you install my god you have to institute gsm hendra then if you want it to a support drag-and-drop you have to insert the dragons or if you wanted to create scoreboard you have to install the scoreboard yourself manager internal crap and of course Latino manager says the IO this is something like 212 lines of code and we have a simple code to show you that and this hinders only basic scrolling basic internal scrub management and very limited 70 panel with the MLT now six lines of code and I swear you have to check it out it's very easy you can compare the two files and find out that you know one code is going to do so much compared with what you have to do before we started it one code which checks any object is going to handle all the dragon's lair all right all the dragon's lair and all the things window genican input to manage the scrap we have to use to AP is the exit convert from publix crap and we're going to take whatever is on the physics Club converted something that your application and in HD can understand and convert to public scrubs is going to take whatever is our internal scrub board of MLT to go to fix weapon this is very cool Jackson save and open same thing you person s a spec Cyrus and Aikido of file type so we're going to find out and we're going to be able to open you txt file simple text files plain unicode files or txt and files and at that point just a matter of calling one API the static text display so people have been asking for that and the ex and Rowena code text box is a solution if you want to display mono style unicode texture by default the only parameters you have to pass are the text or length or CF string depending on what you do ooh which is better so the text a rectangle to do the word wrap and if you want you can pass like you know a bunch of flags in the option structure which are we gonna in the vertical text rotation plushness if you want to justify the texture and if you'd like you can pass your own at freestyle you don't have to if you don't want we'll take whatever is in the queue and grasp or convert the font the font size and the style attribute to something that that's we can understand ok my conclusion slide very difficult think different and unique ID is going more important and I think we're the right technology is now for you to use and to implement easily in Europe gation if you have very specific needs and you need fine control or whether bleach should be displayed use a tree at least the solution it's the only way to display unicode text correctly if you want to return something little bit easier actuation swearinger MLT is the solution MLT is like the text package is going to do so much for you is going to shoot you from like adding to deal with the complexity of a toolbox for the scrolling with the complexity of GSM finding to write scripts and Unicode input once again since unicode this is the only way where things are going it's not only a platform it's windows it's the internet download now and your application at one point is enough to get with unicode so think about our technologies carbon leave nine and ten the same set of api is going to be working pink MLT MLT is great with simple code and show you but in the documentation switching from text edit implementation to MIT is going to reduce the number of lines in your car mlc is going to do like many things but you had to end up by yourself before so it's a nice way to transition to go to carbon nib and move forward to dinner before we go to the 2 i'd like to show you just where you can find more information on the developer.apple.com in the text additional services we have a list of like the current technologies so you'll find info on specific topics like gsm you should like at three MLT TCO text encoding converter there is an energy sdk of the labor i don't know if it's already on the net if it's on the on apple website i saw it last week where the kitchen on sunday and it's great there are latino carbon examples by examples of like how to use MLT how to create the font menu how to use TX a new object how to endure the events even if using carbon event it very nice it is well documented on the road map so yesterday you hope you did go to the carnival valor if you didn't very still like you know i think some refresh some people are going up some slides after that mac OS x on management this is the right place to find out about how the question for management is going to be going they'll be talking about the photo objects API how to access probably like you know the front tables and all these things it's pretty nice quarter quarks will be exposing some of the api's but now you can use on 10 what is the way to go it's a very nice rendering in giant or technologies will be using it if you need more internal please go there advanced printing once again if you move to walk then you know that the printer architecture is changing of course if you use energy that will be transparent for you but if you need to do your own printing please go to availability of information important session 9 12 it is a feedback forum for text and international we have a bunch of Engineers where come by we can talk near those actual specific crimes implementation request it's always good to a feedback on the technologies working on talking about feedback will have I think some balloons in the hole for lunch the International lunch will have like two different tables I think one for phones one for text and 143 please come by if you have like you know once again if you want more information of specific requests or it's like a good way to talk to the engineers that are working on the technologies we have a bunch of people there all right hope you like this of course we have some Q&A
