PyGame bitmap and texmap fonts

Classes

class _PyGameFontProvider( TTFFontProvider ):

Singleton for creating new PyGameBitmapFonts

__init__( self )

create( self , fontStyle , mode = None )

Create a new font for the given fontStyle and mode

enumerate( self , mode = None )

Iterate through all available font-keys (whether instantiated or not)

This uses the wxFontEnumerator class to provide a list of font names from the wxPython system, (with all names lowercased).

key( self , fontStyle , mode = None )

Calculate the key for the fontStyle

match( self , fontStyle , mode = None )

Attempt to find matching font-file for our fontstyle

Should match any name passed into addFontFile, as well as the short filename for the font.

class PyGameBitmapFont( NoDepthBufferMixInBitmapFontMixInFont ):

A PyGame-provided Bitmap Font

__init__( self , fontStyle = None , filename = None , size = None )

createChar( self , char , mode = None )

Create the single-character display list

createCharTexture( self , char , mode = None )

Create character's texture/bitmap as a Numeric array w/ width and height

This uses PyGame and Numeric to attempt to create an anti-aliased luminance texture-map of the given character and return it as (data, width, height).

lineHeight( self , mode = None )

Retrieve normal line-height for this font

lists( self , value , mode = None )

Get a sequence of display-list integers for value

Basically, this does a bit of trickery to do as-required compilation of display-lists, so that only those characters actually required by the displayed text are compiled.

NOTE: Must be called from within the rendering thread and within the rendering pass!

textureToList( self , array , metrics , mode = None )

Compile Numeric Python array to a display-list

XXX: use a single texture and coordinates for texmap version

special case ' ' so that it's not rendered as an image...
