Fontconfig and freetype support #13

Closed creemama closed 3 years ago

creemama commented 3 years ago

Before this commit, when running convert commands overlaying text on an image, ImageMagick would output the following warning:

convert: delegate library support not built-in '...' (Freetype) @ warning/annotate.c/RenderFreetype/1873

Even though text would render on the output image, the text looked pixelated. Adding fontconfig and freetype to ImageMagick fixes this.

See the following link for more info: https://web.archive.org/web/20210621064448/https://legacy.imagemagick.org/discourse-server/viewtopic.php?t=21070
