Hi,
the format of the bitmap is the same as the one of text.bmp in winamp 2 skins (or numbers.bmp for a "digits" font)
(see http://www.winamp.com/nsdn/winamp/skinn ... c/main.php)
As long as you respect this layout, the size of the characters doesn't matter.
The Text control has a 'color' attribute (it's not a characteristic of the font itself, you may want to reuse the same font in different places, with different colors).
By the way as for bitamp fonts I thought I had implemented something more generic, but in fact you are right the image must have exactly the same dimension as in winamp skins.
