png2spd

A PNG image to C64 sprite converter

The python script converts a PNG image file into a SpritePad compatible binary file. It can be used to convert sprites for the Commodore 64.

Usage

png_to_spd(input_file, output_file, sprite_width, sprite_height)

input_file: name of the PNG image. Image must be (24X)(21*X) pixels

output_file: name of the sprite file (usually ends with .spd)

sprite_width: usually 24, which is the width of a hires C64 sprite

sprite_height: usually 21, which is the height of a hires C64 sprite

Example

spritesheet_to_spd("spritesheet.png","sprites.spd", 24, 21) loads a PNG file called spritesheet.png and exports it as sprites.spd in C64 SpritePad format.

Note: This script can easily be included into your make file, making it quite convenient to update sprites in an image editor (I use Asesprite) and save the bitmap file into the project folder of your C64 production. At compile time, the script takes the newest image file and converts it into a binary sprite file.

Dependencies

Uses Pillow image manipulation library
