SVGFonts
This library parses the SVG-Fonts format which is in XML, so it is easy to manipulate by hand (See http://www.w3.org/TR/SVG/fonts.html).
Features:
- Complete implementation of the SVG-Font format
- Outline generation with elimination of holes for easy extrusion
- Kerning (i.e. the two characters in "VA" have a shorter distance than in "VV")
- Rasterization with with antialiasing (subsampling with 256 grey values) (soon)
- Font-Cache
Usage:
You can convert your favourite font (i.e. .ttf) into a .svg file with fontforge (the menu item under
"Save All"). If a font converted on your own doesn't work, try the repair options, and if this still
doens't work edit the file by hand or even cooler: help me with a patch to make this library more robust.
Remember that a lot of fonts are not allowed to be distributed freely.
Example:
src/Test/Font.hs generates a Collada file that can be read with tools like blender.
The data that is passed to genCollada is represented with a data type that I use for all my libraries to allow easy combination.
The main function to generate a visual representation of a string is:
displayString :: String -> (Int,Int) -> Props -> Transf -> Mode -> Spacing -> O -> V -> V -> P -> TexMap -> [Geometry]
The list [AObj] can contain various data:
- Textures that can be used directly by OpenGL (TextureObject)
- Names of texture files in the fontcache (collada-output needs this)
- Extruded or non extruded outlines
