bitblt is a (possibly) faster sprite blitter for Gamebuino with support for gray pixels.
Signature:
void bitblt( const uint8_t* sprite, int8_t x, int8_t y, bool hide_grey );- sprite: the pointer to sprite data generated with bbltenc
- x: the horizontal screen coordinate
- y: the vertial screen coordinate
- hide_grey: if
true, grey pixels will appear white; iffalse, grey pixels will appear black
bbltenc creates a C byte array with sprite data suitable to use with bitblt from a PNG image.
It uses a different format for sprites that takes 2 + width * ( ( height + 7 ) / 8 ) * 2 bytes for an image with width * height pixels.
Usage:
$ bbltenc -h
USAGE: bbltenc [ -n array_name ] [ -o output_path ] input_path
-n array_name set the generated array name (default = sprite)
-o output_path set the name of the generated file (default = stdout)
input_path set the name of the PNG image
- bitblt: Probably some, if you find one let me know: @leiradel
- bbltenc: Only handles 32 bpp PNGs with alpha channel
