Hi,

I'm trying to render color Emoji with PANGO and Noto Color Emoji Font.
However, the rendered Emoji become black & white.

The Emoji is supposed to be like this:

How to reproduce:

This is the command:

Code: Select all

convert -background white -size 600x50 \
pango:"<span font=\"Noto Color Emoji\" size=\"24576\">🦖</span> <span font=\"Noto Sans CJK TC\" size=\"24576\" color=\"green\">T-Rex in Traditional Chinese is 暴龍</span>" \
pango.jpg

This is the debug message:

Code: Select all

convert -debug all -background white -size 600x50 pango:"<span font=\"Noto Color Emoji\" size=\"24576\">🦖</span> <span font=\"Noto Sans CJK TC\" size=\"24576\" color=\"green\">T-Rex in Traditional Chinese is 暴龍</span>" pango.jpg

The Unicode of the T-Rex Emoji is \u{1f996} (in case the character lost for whatever reason). The T-Rex Emoji is an Unicode 10 Emoji added recently. The Noto B&W Emoji doesn't support it so I'm pretty sure the Emoji was rendered with Noto Color Emoji. (The issue applies to old Emoji too.)

How may I render the Emoji with color?

Thanks a lot

Your IM version is over 100 versions old. Your Pango is old also. I am using IM 6.9.9.20 and pango @1.40.11_0. You might try upgrading. Also can you zip your font and post it to some free hosting service such as dropbox.com and put the URL here. That way we can try to test it on current version. Alternately, provide a link to the font.

What is your platform? I am not sure those color fonts work on anything but Linux. Not Mac or Windows.

I tried using 6.8.9.9 Q16 Mac OSX

Code: Select all

convert -background white -size 600x50 \
pango:"<span font=\"/Library/Fonts/NotoColorEmoji\" size=\"24576\">🦖</span>" \

And do not even get the shape of your desired font.

In your code above, it just shows a square for the character. Is that correct or has it been changed from what you wanted for the character needed?

I compared the character you provided will mine, the character is correct.

May I know what is the proper way to upgrade / install Imagemagick and PANGO?

You may need the freetype 2.5 or higher delegate. But I have had no success with that on my Mac

See
https://github.com/googlei18n/noto-emoji/issues/36
https://www.freetype.org

FreeType 2.5

2013-06-19
FreeType 2.5 has been released. A major new feature is support for color embedded bitmaps (eg. color emoji), contributed by Behdad Esfahbod on behalf of Google. Additionally, Adobe's CFF engine is now the default, which makes a good reason to change from the 2.4.x to the 2.5.x series.

Sorry I do not know about installing on Linux. See

http://www.imagemagick.org/script/download.php
http://www.imagemagick.org/script/insta ... e.php#unix
http://www.imagemagick.org/script/advan ... lation.php

If you install from source, you will need to install all your needed delegates manually and before installing ImageMagick.

On Linux, it is best to use some RPM.

Try a color background and see if that makes any difference. Just not white/gray/black. So for example try -background pink. Perhaps ImageMagick sees the white background and thinks the image should be grayscale.

If that works, try

Code: Select all

convert -background white -size 600x50 -set colorspace sRGB \
pango:"<span font=\"Noto Color Emoji\" size=\"24576\">🌏</span> <span font=\"Noto Sans CJK TC\" size=\"24576\" color=\"green\">Earth in Traditional Chinese is 地球</span>" \
