basis_universal/basisu_tool.cpp
Rich Geldreich 33996b1a5f Important: Changing the Basis file version, so any existing files will need to be recompressed! 
Adding new fields to the basis header: texture type and framerate. Texture type may be 2D, 2D array, video, volume, or cubemap array. The compressor makes sure that anything other than pure 2D follows certain constraints (cubemap arrays must have a multiple of 6 input images, videos/texture array images all must have the same resolution/# of mipmaps, etc.)
When unpacking cubemaps, the -unpack command now writes cubemap .KTX files which various tools like PVRTexTool support.

"The default mode is compression of one or more PNG 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"
" -compare: Compare two PNG images specified with -file, output PSNR and SSIM statistics and RGB/A delta images\n"
"\n"
"Important: By default, the compressor assumes the input is not sRGB. If the input is sRGB (diffuse/albedo textures, images, etc), be sure to specify -srgb for much better compression.\n"
"\n"
"Options:\n"
" -file filename.png: Input image filename, multiple images are OK, use -file X for each input filename (prefixing input filenames with -file is now optional)\n"
" -alpha_file filename.png: 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"
" -srgb: Use perceptual colorspace metrics for significantly higher rate distortion performance on sRGB textures. Don't use on non-sRGB inputs.\n"
" -q X: Set quality level, 1-255, default is 128, lower=better compression/lower quality/faster, higher=less compression/higher quality/slower, default is 128\n"
" -output_file filename: Output .basis/.ktx filename\n"
" -output_path: Output .basis/.ktx files to specified directory\n"
" -debug_output: Enable codec debug print to stdout (slightly slower)\n"
" -debug_images: Enable codec debug images (much slower)\n"
" -compute_stats: Compute and display image quality metrics (slightly slower)\n"
" -slower: Enable optional stages in the compressor for slower but higher quality compression\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.)"
" -framerate X: Set framerate in header to X/frames sec\n"
"\n"
"More options:\n"
" -max_endpoint_clusters X: Manually set the max number of color endpoint clusters from 1-8192, use instead of -q\n"
" -max_selector_clusters X: Manually set the max number of color selector clusters from 1-7936, use instead of -q\n"
" -y_flip: Flip input images vertically before compression\n"
" -normal_map: Tunes codec parameters for better quality on normal maps (no selector RDO, no sRGB)\n"
" -no_alpha: Always output non-alpha basis files, even if one or more inputs has alpha\n"
" -force_alpha: Always output alpha basis files, even if no inputs has alpha\n"
" -seperate_rg_to_color_alpha: Seperate input R and G channels to RGB and A (for tangent space XY normal maps)\n"
" -no_multithreading: Disable OpenMP multithreading\n"
"\n"
"Mipmap generation options:\n"
" -mipmap: Generate mipmaps for each source image\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_smallest X: Set smallest pixel dimension for generated mipmaps, default is 1\n"
" -mip_srgb: Convert image to linear before filtering, then back to sRGB\n"
"\n"
"Backend selector RDO codec options:\n"
" -no_selector_rdo: Disable backend's selector rate distortion optimizations (slightly faster, less noisy output, but lower quality per output bit)\n"
" -selector_rdo_thresh X: Set selector RDO quality threshold, default is 1.25, lower is higher quality but less quality per output bit (try 1.0-3.0)\n"
"\n"
"Hierarchical virtual selector codebook options:\n"
" -global_sel_pal: Always use vitual selector palettes (instead of custom palettes), slightly smaller files, but lower quality, slower encoding\n"
" -no_auto_global_sel_pal: Don't automatically use virtual selector palettes on small images\n"
" -no_hybrid_sel_cb: Don't automatically use hybrid virtual selector codebooks (for higher quality, only active when -global_sel_pal is specified)\n"
" -global_pal_bits X: Set virtual selector codebook palette bits, range is [0,12], default is 8, higher is slower/better quality\n"
" -global_mod_bits X: Set virtual selector codebook modifier bits, range is [0,15], defualt is 8, higher is slower/better quality\n"
" -no_endpoint_refinement: Disable endpoint codebook refinement stage (slightly faster, but lower quality)\n"
" -hybrid_sel_cb_quality_thresh X: Set hybrid selector codebook quality threshold, default is 2.0, try 1.5-3, higher is lower quality/smaller codebooks\n"
"\n"
"Set various fields in the Basis file header:\n"
" -userdata0 X: Set 32-bit userdata0 field in Basis file header to X (X is a signed 32-bit int)\n"
" -userdata1 X: Set 32-bit userdata1 field in Basis file header to X (X is a signed 32-bit int)\n"
"\n"
"Various command line examples:\n"
"basisu -srgb -file x.png -mipmap -y_flip : Compress a mipmapped x.basis file from an sRGB image named x.png, Y flip each source image\n"
"basisu -validate -file x.basis : Validate x.basis (check header, check file CRC's, attempt to transcode all slices)\n"
"basisu -unpack -file x.basis : Validates, transcodes and unpacks x.basis to mipmapped .KTX and RGB/A .PNG files (transcodes to all supported GPU texture formats)\n"
