photoMimeType
The MIME type of a photo asset.
Declaration
attribute String photoMimeType;Discussion
The MIME type is either as detected from a network request for the asset (if the MIME type was provided as a URL on photoSrc) or as provided by the developer prior to assigning a prepared ArrayBuffer to photoSrc.
This property, while writable, behaves as read-only if the photo was obtained through a network request to a string URL set on photoSrc. In this case, writes to this property are ignored.
However, if the intent is to assign an already loaded ArrayBuffer to photoSrc, you must set this property to the correct MIME type beforehand. This type is usually image/jpeg, but can vary if you provide a different image format. In that case, the property defaults to the value image/jpeg.
