"Available options:\n"
" -r # Maximum resolution, where # is a power of 2. For example, 256 pixels would be \"-r 8\"\n"
" -s Stretch the image when non-pot or mismatched size, as opposed to fitting it within.\n"
" -c # Defines the number of colors in the palette, counting from 1. Maximum 256.\n"
" -o Opaque mode. Do not make the first color in the image palette transparent.\n"
" The background of letterboxed images is internally set to the first palette color,\n"
" so using this setting with different image sizes will cause visible bars to appear\n"
" unless you combine it with the -s option, which will always fill the canvas for each\n"
" frame. The same is true for all imported frames which contain an alpha channel.\n"
" -d Don't run COMPIMG, don't delete temporary files. Useful if COMPIMG is broken for some\n"
" reason, or if you want to customize the command line options given to it.\n"
// " -l Enable Lanczos filtering when scaling the image.\n" //point filter unimplemented
//" -w Specify the number of subdivisions to make horizontally per frame.\n"
//" Use this if you are importing a spritesheet. Each cut is perfectly even.\n"
//" Note that this process happens AFTER importing each image, and will be\n"
//" applied to each one separately. DO NOT use this to combine a spritesheet"
//" with individual frames or you will have a very, very bad time."
//" -h Same as -w, but vertical. If used with -w, KAvEAT will create each chunk\n"
//" from each row left-to-right first, not each column top-to-bottom.\n"
