I'm trying to convert a glyph from the Mac OS X "Apple Color Emoji.ttf" font to a PNG.

convert -font ./Apple\ Color\ Emoji.ttf -background none -pointsize 96 label:$x $x.png

$x refers to the label. The above generates a blank image. Any thoughts on what I might be doing wrong?

It should work, giving black letters. What version of IM are you using?

bash-3.2$ convert --version
Version: ImageMagick 6.7.7-6 2013-03-27 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC
Features: OpenCL

Also, I'd like the resulting image to have the same colors as the glyph.

Despite the apparent date, 6.7.7 is an ancient version. I suggest you upgrade and try the command again.

I just downloaded and compiled/linked the latest source:

Version: ImageMagick 6.8.4-2 2013-03-28 Q16 http://www.imagemagick.org

I'm still seeing just blank images, (or white if I remove the -background none option.)

This particular font is a color font with embedded bitmaps: http://typographica.org/typeface-review ... lor-emoji/

... a color font with embedded bitmaps ...

Ah. Doubtless that's the issue.

I'm getting the same problem with ImageMagick 6.9.2-10
Is it possible that since 2013 ImageMagick still not support these kind of fonts ?

As far as I know, those color emojis are not fonts that IM supports. Typical fonts are .ttf and a few others.

ImageMagick relies on the Freetype delegate library to render TrueType fonts. If Freetype cannot read the font, there is no hope that ImageMagick will be able to render the characters. ImageMagick cannot read AppleColorEmoji.ttf. Try it with the Freetype library utilities. If it can read it-- that would indicate a bug in ImageMagick.

From what I know freetype support Apple color emoji TTF font since version 2.5.2

We tried a couple of font renderers available on Linux and they failed to grok Apple color emoji TTF. We'll keep investigating and see if we can find a solution.

How can I simple test if freetype support the Apple color emoji font well ??
I didn't find a sample application to use for test freetype font support

Freetype includes a separate download for their demos. Fedora, for example, includes these in the repos as freetype-demos. Use one of the demo programs to verify if Freetype can grok your TTF file. If so, we can assume the rendering problem is with ImageMagick.

I found these references that clearly state that freetype support the coloured emojis font.

I finally tested using ftview and it worked.
