I want to generate a
.PNG image for every glyph in a
.TTF font file. How do I do that?
You can use Python with FontForge, it has a Python 2.7 interpreter.
On Windows: after installing FontForge, locate the "bin" in installation path and add it to the Windows system path, in my case it is:
c:\Program Files (x86)\FontForgeBuilds\bin\
This dir contains
ffpython.exe so after adding it to PATH you can directly
.py script in console.
> ffpython myscript.py
To export all glyphs you can use this simple script:
import fontforge F = fontforge.open("perpetua.ttf") for name in F: filename = name + ".png" # print name F[name].export(filename) # F[name].export(filename, 600) # set height to 600 pixels
This may be an old question, but I found the following batch file works with ImageMagick 7:
@ECHO OFF set f=wingding.TTF set ps=400 set bg=white set ext=png set s=600x600 set alpha=A B C D E F G H I J K L M N O P Q R S T U V W Z Y Z set num=0 1 2 3 4 5 6 7 8 9 For %%X in (%alpha% %num%) do ( convert -font %f% -pointsize %ps% -size %s% -background %bg% label:%%X %%X.%ext%) pause exit
NOTE: This conversion only works with a limited selection of font characters. It works well for all capital letters. Just install ImageMagick and make sure it is in your environment path. Include "legacy" commands in your installation.
This online app does just that very easily and visual - although is not open source :( it could help to quickly generate transparent glyphs pngs from given ttf to quickly test. and a manifest of all the glyphs dimensions and features: http://kvazars.com/littera/
fontforge has switched to a python scripting language. Create a file exportGlyphs.py:
import os from fontforge import * font = open(os.sys.argv) for glyph in font: if font[glyph].isWorthOutputting(): font[glyph].export(font[glyph].glyphname + ".png")
Then run fontforge as:
fontforge -script exportGlyphs.py YOURFONT.ttf
Bingo. A whole bunch of .png files for each glyph.
