"The default mode is compression of one or more PNG/BMP/TGA/JPG files to a .basis file. Alternate modes:\n"
" -unpack: Use transcoder to unpack .basis file to one or more .ktx/.png files\n"
" -validate: Validate and display information about a .basis file\n"
" -info: Display high-level information about a .basis file\n"
" -compare: Compare two PNG/BMP/TGA/JPG images specified with -file, output PSNR and SSIM statistics and RGB/A delta images\n"
" -version: Print basisu version and exit\n"
"Unless an explicit mode is specified, if one or more files have the .basis extension this tool defaults to unpack mode.\n"
"\n"
"Important: By default, the compressor assumes the input is in the sRGB colorspace (like photos/albedo textures).\n"
"If the input is NOT sRGB (like a normal map), be sure to specify -linear for less artifacts. Depending on the content type, some experimentation may be needed.\n"
"\n"
"Filenames prefixed with a @ symbol are read as filename listing files. Listing text files specify which actual filenames to process (one filename per line).\n"
"\n"
"Options:\n"
" -opencl: Enable OpenCL usage\n"
" -opencl_serialize: Serialize all calls to the OpenCL driver (to work around buggy drivers, only useful with -parallel)\n"
" -parallel: Compress multiple textures simumtanously (one per thread), instead of one at a time. Compatible with OpenCL mode. This is much faster, but in OpenCL mode the driver is pushed harder, and the CLI output will be jumbled.\n"
" -ktx2: Write .KTX2 ETC1S/UASTC files instead of .basis files. By default, UASTC files will be compressed using Zstandard unless -ktx2_no_zstandard is specified.\n"
" -ktx2_no_zstandard: Don't compress UASTC texture data using Zstandard, store it uncompressed instead.\n"
" -ktx2_zstandard_level X: Set ZStandard compression level to X (see Zstandard documentation, default level is 6)\n"
" -ktx2_animdata_duration X: Set KTX2animData duration field to integer value X (only valid/useful for -tex_type video, default is 1)\n"
" -ktx2_animdata_timescale X: Set KTX2animData timescale field to integer value X (only valid/useful for -tex_type video, default is 15)\n"
" -ktx2_animdata_loopcount X: Set KTX2animData loopcount field to integer value X (only valid/useful for -tex_type video, default is 0)\n"
" -file filename.png/bmp/tga/jpg/qoi: Input image filename, multiple images are OK, use -file X for each input filename (prefixing input filenames with -file is optional)\n"
" -alpha_file filename.png/bmp/tga/jpg/qoi: Input alpha image filename, multiple images are OK, use -file X for each input filename (must be paired with -file), images converted to REC709 grayscale and used as input alpha\n"
" -multifile_printf: printf() format strint to use to compose multiple filenames\n"
" -multifile_first: The index of the first file to process, default is 0 (must specify -multifile_printf and -multifile_num)\n"
" -multifile_num: The total number of files to process.\n"
" -q X: Set ETC1S quality level, 1-255, default is 128, lower=better compression/lower quality/faster, higher=less compression/higher quality/slower, default is 128. For even higher quality, use -max_endpoints/-max_selectors.\n"
" -linear: Use linear colorspace metrics (instead of the default sRGB), and by default linear (not sRGB) mipmap filtering.\n"
" -output_file filename: Output .basis/.ktx filename\n"
" -output_path: Output .basis/.ktx files to specified directory.\n"
" -debug: Enable codec debug print to stdout (slightly slower).\n"
" -verbose: Same as -debug (debug output to stdout).\n"
" -debug_images: Enable codec debug images (much slower).\n"
" -stats: Compute and display image quality metrics (slightly slower).\n"
" -tex_type <2d, 2darray, 3d, video, cubemap>: Set Basis file header's texture type field. Cubemap arrays require multiples of 6 images, in X+, X-, Y+, Y-, Z+, Z- order, each image must be the same resolutions.\n"
" 2d=arbitrary 2D images, 2darray=2D array, 3D=volume texture slices, video=video frames, cubemap=array of faces. For 2darray/3d/cubemaps/video, each source image's dimensions and # of mipmap levels must be the same.\n"
" For video, the .basis file will be written with the first frame being an I-Frame, and subsequent frames being P-Frames (using conditional replenishment). Playback must always occur in order from first to last image.\n"
" -framerate X: Set framerate in .basis header to X/frames sec.\n"
" -individual: Process input images individually and output multiple .basis/.ktx2 files (not as a texture array - this is now the default as of v1.16)\n"
" -tex_array: Process input images as a single texture array and write a single .basis/.ktx2 file (the former default before v1.16)\n"
" -comp_level X: Set ETC1S encoding speed vs. quality tradeoff. Range is 0-6, default is 1. Higher values=MUCH slower, but slightly higher quality. Higher levels intended for videos. Use -q first!\n"
" -fuzz_testing: Use with -validate: Disables CRC16 validation of file contents before transcoding\n"
"\nUASTC options:\n"
" -uastc: Enable UASTC texture mode, instead of the default ETC1S mode. Significantly higher texture quality, but larger files. (Note that UASTC .basis files must be losslessly compressed by the user.)\n"
" -uastc_level: Set UASTC encoding level. Range is [0,4], default is 2, higher=slower but higher quality. 0=fastest/lowest quality, 3=slowest practical option, 4=impractically slow/highest achievable quality\n"

" -mip_scale X: Set mipmap filter kernel's scale, lower=sharper, higher=more blurry, default is 1.0\n"
" -mip_filter X: Set mipmap filter kernel, default is kaiser, filters: box, tent, bell, blackman, catmullrom, mitchell, etc.\n"
" -mip_renorm: Renormalize normal map to unit length vectors after filtering\n"
" -mip_clamp: Use clamp addressing on borders, instead of wrapping\n"
" -mip_fast: Use faster mipmap generation (resample from previous mip, not always first/largest mip level). The default (as of 1/2021)\n"
