In March, Nick asked the following: Using the latest freetype 2.5.3 the Apple Color Emoji.ttf file on a Mac works fine. However freetype fails to load the glyphs using an iPhone's `[email protected]' file.
It looks like either the iphone sbix format used is slightly different, or the png format has been customized...? I've now had a closer look, and I can finally answer it :-) The format of this font's sbix table is indeed different. It uses an `rgbl' graphic type, which is officially unsupported by Apple, according to the recently published sbix specification. https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6sbix.html It shouldn't be too hard to implement the `rgbl' type in FreeType, since it appears to be an uncompressed format with four bytes per pixel, but I doubt that it makes sense, given the fast pace of iOS versions. I suppose that recent emoji fonts of Apple use one of the much more compact formats like `png' that should shrink the font size a lot.
