Bitmap fonts as easy as text. Color is changeable with the color statement. This was made only for one font (at time), but can be expanded to use multiple fonts. For example, replacing img_font, img_char and Fontstring$ for arrays. This is for monospaced fonts only. Here is a sample bitmap font ;==================================================================== ; Project: Use Bitmapfonts to replace text ; Version: 1.0 ; Author: Dan ; Email: ... ; Copyright: PD ; Description: As simple as text x,y,txt$. ; Replace Text To textf. ; Use Color r,g,b to change the font Color ; Create fonts with the FontString$ (for example with fony: http://hukka.ncn.fi/?fony ) ; Textf function is using the backbuffer to render text. Change this on need. ;==================================================================== Global FontString$="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!?$%^&()_+-=;'#:@~,./<>?\\|" Global img_font, img_char img_font=LoadAnimImage("MyAmigaFont8x8x89.png",8,8,0,89) img_char=CreateImage(ImageWidth(img_font),ImageHeight(img_font)) MaskImage img_font,$ff,$ff,$ff ;Set Foreground color (of the font) as mask, so the font color can be changed with color statement !
