Standard Edition

Update V3.7c

Bitmap2LCD is a software tool for programming small Graphic LCDs in embedded systems and a programmable text and graphic processing tool.

Bitmap2lcd generates GLCD FONTS from UNICODE and ANSI SYSTEM FONTS  ( fonts currently installed in Windows ) and from EDITABLE FONTS, chars and symbols you can create yourself. Chars of a System Font can be exported to EDITABLE FONTS to be freely editable.

Font Chars can also be stretched. ( See below, the panel above the displayed Character A )
