Crate flow_texpack 

flow-texpack is a program that will allow you to generate texture atlas from input images (BMP, HDR, JPG, PNG, TGA, TIFF, WEBP). The application generates both texture atlas and descriptions file that can be read by a game.

Usage

Show available options:

flow-texpack -h

or

flow-texpack --help

Examples

Generate from input data/characters and data/tiles, write output to out/atlas and enable the options: premultiply pixels by their alpha channel, trim excess transparency off the textures, remove duplicate textures from the atlas, enable rotation of textures 90 degrees clockwise, pad each texture by 2 pixels and finally enable verbose output mode.

flow-texpack -i data/characters data/tiles -o out/atlas -m -t -u -r -p 2 -v

Enable load filter so that only TGA images are included in the texture atlas:

flow-texpack -i data/tiles -o out/atlas --load-filter tga -v

Enable rect heuristic AreaFit:

flow-texpack -i data/tiles -o out/atlas --rect-heuristic area-fit -v

Enable output atlas size of 2048x2048:

flow-texpack -i data/tiles -o out/atlas --atlas-size pot2048 -v

Read input files/directories from input.txt but exclude all in exclude.txt:

flow-texpack --input-file input.txt --exlude-file exclude.txt -o out/atlas -v

Adjust atlas size automatically so that texture will fit:

flow-texpack -i data/characters -o out/atlas --adjust-size -v

Adjust texture size so that it will fit given atlas size:

flow-texpack -i data/characters -o out/atlas --adjust-fit -v
