This tool is able to convert a font of png format to binary font format and c raw data for RetroArch rgui and mame2003plus.
1 Install libraries
to build in linux environment
sudo apt install libsdl1.2-dev libsdl-image1.2-dev
to build in windows environment (msys2 mingw64)
pacman -S mingw-w64-x86_64-SDL
pacman -S mingw-w64-x86_64-SDL_image
2 Make binary
make
3 Convert png file to c
./png2c
./png2c bitmap_cyrillic.png
bitmap_cyrillic.h - c raw data file and
bitmap_cyrillic.bin - RetroArch binary font file are generated.
/* FontName = bitmap_cyrillic.png */
/* generated with png2c by trngaje */
#define FONT_WIDTH 6
#define FONT_HEIGHT 10
static const unsigned char bitmap_bin[] = {
0x02, 0x01, 0x7C, 0xC1, 0x17, 0x7C, 0x00, 0x00,
0x80, 0x02, 0x7C, 0xC1, 0x17, 0x7C, 0x00, 0x00,
