OpenGLContext.scenegraph.text._toolsfont

fonttools-based direct extraction of TTF outlines

Most of the complexity of this module has been refactored into the ttfquery package, which provides for finding system fonts, generating registries of available fonts, querying metadata regarding a particular font/glyph etc.

Classes

class Font( object ):

Holder for metadata regarding a particular font

XXX Note: currently there is no distinction between the Context-specific metadata and the generic descriptions of the fonts. For instance, there is no reason that the underlying glyph metadata needs to be queried for each quality level of a given font (only the outlines need to be regenerated), and the outlines themselves are not actually dependent on the context, so they can be shared across contexts, with only the display lists not being shareable.

__init__( self , filename , encoding = None , glyphClass = None , quality = 3 )

Initialize the font

filename: a file source from which to load the .ttf file, must be a simple local filename, not a URL or font-name.
encoding: the TrueType encoding specifier, the specifier is two elements, a PlatformID and a platform-specific ID code (sub encoding). http://developer.apple.com/fonts/TTRefMan/RM06/Chap6name.html#ID the default should be the Unicode Roman if I've done my homework correctly.

(0,0) or (0,3) -- Unicode (default or Unicode 2.0 semantics respectively), I have no fonts with which to test this encoding. (3,1) -- Latin-1 Microsoft encoding, while (1,0) should be the Mac-Roman encoding. You will almost certainly want (3,1) on windows, and I'm guessing (1,0) on Mac. glyphClass -- the class used for creating new glyphs, if not provided, self.defaultGlyphClass is used. quality -- rendering quality for the font, the number of integration steps for each quadratic curve in the font definition.

__repr__( self )

Provide a representation of the Font

_countGlyphs( self , string )

_createGlyph( self , character , quality )

Load glyph outlines from font-file (called via withFont)

_createGlyphs( self , set )

Create glyphs for the sequence of passed characters (called via withFont)

_generalMetadata( self )

Load general meta-data for this font (called via withFont)

Guess the appropriate encoding, query line height, and character height.
