i make this tool for my ds to make loading texture easier...
|
|
desgined for my personal use only....
|
|
its not really optimized and use really minimal error checking
|
|
|
|
please use something more stable like ptexconv or grit instead!
|
|
|
|
since ptexconv and grit just simply convert image data into loose Binary
|
|
i tried to create header with the metadata information of the image
|
|
|
|
the idea is to simply load image data without worrying about image metadata.
|
|
the metadata contain basic stuff like width, height, format, etc...
|
|
|
|
color palette are embedded in the file.
|
|
a palette hash is provided. this can be used to comparing
|
|
whether another image uses the same palette
|
|
|
|
usage: sillyimage -i <input image> -o <output dir> [options]
|
|
|
|
options:
|
|
-i, --input input files [required] [may be repeated]
|
|
-o, --out output directory [required]
|
|
-h, --help shows help message and exits
|
|
-v, --version prints version information and exits
|
|
-f, --format texture format { rgb256, rgb16, indexed4, indexed16, indexed256, indexed32a3, indexed8a5 } [default: "rgb16"]
|
|
|
|
binary format:
|
|
[string] sillyimg (0x676D69796C6C6973 in hex or 7452728928599042419 in decimal (uint64))
