Display flags
A 32-bit integer containing flags that describe how the text should be drawn.
Overview
The following flags are defined:
- Don’t auto scale
Controls text scaling. If this flag is set to
1, the text media handler reflows the text instead of scaling when the track is scaled. This flag’s value is0x0002.- Use movie background color
Controls background color. If this flag is set to
1, the text media handler ignores the background color field in the text sample description and uses the movie’s background color instead. This flag’s value is0x0008.- Scroll in
Controls text scrolling. If this flag is set to
1, the text media handler scrolls the text until the last of the text is in view. This flag’s value is0x0020.- Scroll out
Controls text scrolling. If this flag is set to
1, the text media handler scrolls the text until the last of the text is gone. This flag’s value is0x0040.- Horizontal scroll
Controls text scrolling. If this flag is set to
1, the text media handler scrolls the text horizontally; otherwise, it scrolls the text vertically. This flag’s value is0x0080.- Reverse scroll
Controls text scrolling. If this flag is set to
1, the text media handler scrolls down (if scrolling vertically) or backward (if scrolling horizontally; note that horizontal scrolling also depends upon text justification). This flag’s value is0x0100.- Continuous scroll
Controls text scrolling. If this flag is set to
1, the text media handler displays new samples by scrolling out the old ones. This flag’s value is0x0200.- Drop shadow
Controls drop shadow. If this flag is set to
1, the text media handler displays the text with a drop shadow. This flag’s value is0x1000.- Anti-alias
Controls anti-aliasing. If this flag is set to
1, the text media handler uses anti-aliasing when drawing text. This flag’s value is0x2000.- Key text
Controls background color. If this flag is set to
1, the text media handler does not display the background color, so that the text overlay background tracks. This flag’s value is0x4000.
