C# lib for processing font files - TTF (TrueType),

问题:

Any known C# library or project out there that can understand the TTF file format? Most questions Ive seen regarding this are attempting to do custom rendering, but I'm more interested in a font editor type of application.

回答1:

Don't know what you want to do exactly, but WPF has a cool GlyphTypeface Class that is quite abstract and quite independent.

This is how you can start with:

GlyphTypeface ttf = new GlyphTypeface(new Uri(@"c:\windows\fonts\verdana.ttf"));

There are also the GlyphRun Class and the GlyphRunDrawing Class.

Otherwise, if you're looking for the big picture, open-source, you can also check the FreeType Project, available here: http://freetype.org/

and access advanced typography data.

(such as GDEF,GSUB,GPOS) etc.

The below image shows some screen snapshot,

compare then lib's rendering glyph 'B'

1. (left) : glyph from the lib without Hinting

2. (middle) : Windows's GDI with clear type (from notepad)

3. (right): glyph from the lib with True Hinting

snap 2: I'm developing auto-hint, and grid fitting.

test it out, and feel free to comment, fork, discuss.

There is a .net wrapper for FreeType available here: https://github.com/Robmaister/SharpFont
