Crunchitize is a tool to assist in making Crunch compressed DXT textures. It currently converts PNG images, and by default makes them pre-multiplied to be friendly to pixi.js. If it finds a .json file with the same name as a converted .png, it also modifies that json file's meta.image property to point at the new texture file instead of the (assumed) png. Crunchitize can resize your images for you, but the output texture must have dimensions that are each a multiple of 4.
-f, --files Glob path or path to .txt file list of glob paths to .pngs to process.
-q, --quality Quality of crunch output, 0-1. Default is 0.5.
-pm, --premultiplied If the input pngs should be converted to premultiplied alpha images first. Default is true.
-n, --noise Strength of noise to apply to image before processing, from 0-1 (small numbers suggested). Default is 0.
--format 'crn' for .crn, or 'dds' for .dds. Default is 'crn'.
-d, --deleteInput If the input pngs should be deleted after being converted. Default is false.
-r, --resize How to resize input images to be multiple of 4 dimensions. Options are 'scale' to scale up, 'border' to add transparency to the right and bottom. The default is to not resize, and skip invalid images.
crunchitize -f path/to/my.png
crunchitize -f path/to/folder/ -q 1
crunchitize -f path/to/folder/ --format dds
list.txt:
path/to/my.png 0.8
path/to/other.png 0.3 scale
path/to/another.png border
shell:
crunchitize -f path/to/list.txt
