| "The default mode is compression of one or more .PNG/.BMP/.TGA/.JPG/.QOI/.DDS/.EXR/.HDR files to a LDR or HDR .KTX2 file. Alternate modes:\n" |
| " -unpack: Use transcoder to unpack a .basis/.KTX2 file to one or more .KTX/.PNG files\n" |
| " -validate: Validate and display information about a .basis/.KTX2 file\n" |
| " -info: Display high-level information about a .basis/.KTX2 file\n" |
| " -compare: Compare two LDR PNG/BMP/TGA/JPG/QOI images specified with -file, output PSNR and SSIM statistics and RGB/A delta images\n" |
| " -compare_hdr: Compare two HDR .EXR/.HDR images specified with -file, output PSNR statistics and RGB delta images\n" |
| " -tonemap: Tonemap an HDR or EXR image to PNG at multiple exposures, use -file to specify filename\n" |
| " -version: Print version and exit\n" |
| "\n" |
| "Notes:\n" |
| "\nUnless an explicit mode is specified, if one or more files have the .basis or .KTX2 extension this tool defaults to unpack mode.\n" |
| "\nBy 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" |
| "The TinyEXR library is used to read .EXR images. This library does not support all .EXR compression methods. For unsupported images, you can use ImageMagick to convert them to uncompressed .EXR.\n" |
| "\n" |
| "For .DDS source files: Mipmapped or not mipmapped 2D textures (but not cubemaps) are supported. Only uncompressed 32-bit RGBA/BGRA, half float RGBA, or float RGBA .DDS files are supported. In -tex_array mode, if a .DDS file is specified, all source files must be in .DDS format.\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" |
| " -hdr: Encode input as UASTC HDR (automatic if any input file has the .EXR or .HDR extension, or if any .DDS file is HDR).\n" |
| " -fastest: Set UASTC LDR and HDR to fastest but lowest quality encoding mode (same as -uastc_level 0)\n" |
| " -slower: Set UASTC LDR and HDR to slower but a higher quality encoding mode (same as -uastc_level 3)\n" |
| " -opencl: Enable OpenCL usage (currently only accelerates ETC1S encoding)\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 files (the default). By default, UASTC LDR/HDR files will be compressed using Zstandard unless -ktx2_no_zstandard is specified.\n" |
| " -basis: Write .basis files instead of .KTX2 files (the previous default).\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" |

| " -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 or scaled RGB for HDR), and by default linear (not sRGB) mipmap filtering.\n" |
| " -output_file filename: Output .basis/.KTX2 filename\n" |
| " -output_path: Output .basis/.KTX2 files to specified directory.\n" |
| " -debug or -verbose: Enable codec debug print to stdout (slightly slower).\n" |
| " -debug_images: Enable codec debug images (much slower).\n" |
| " -stats: Compute and display image quality metrics (slightly to much 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" |

| " 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" |
| " -cubemap: same as -tex_type cubemap\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 LDR 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 LDR/HDR encoding level. LDR 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" |
| " UASTC HDR range is [0,4] - higher=slower but higher quality. HDR default=1.\n" |
| " -uastc_rdo_l X: Enable UASTC LDR RDO post-processing and set UASTC RDO quality scalar (lambda) to X. Lower values=higher quality/larger LZ\n" |
| " compressed files, higher values=lower quality/smaller LZ compressed files. Good range to try is [.25-10].\n" |
| " Note: Previous versons used the -uastc_rdo_q option, which was removed because the RDO algorithm was changed.\n" |
| " -uastc_rdo_d X: Set UASTC LDR RDO dictionary size in bytes. Default is 4096, max is 65536. Lower values=faster, but less compression.\n" |
| " -uastc_rdo_b X: Set UASTC LDR RDO max smooth block error scale. Range is [1,300]. Default is 10.0, 1.0=disabled. Larger values suppress more artifacts (and allocate more bits) on smooth blocks.\n" |
| " -uastc_rdo_s X: Set UASTC LDR RDO max smooth block standard deviation. Range is [.01,65536]. Default is 18.0. Larger values expand the range of blocks considered smooth.\n" |
| " -uastc_rdo_f: Don't favor simpler UASTC LDR modes in RDO mode.\n" |
| " -uastc_rdo_m: Disable RDO multithreading (slightly higher compression, deterministic).\n" |
| "\n" |
| "HDR specific options:\n" |
| " -uastc_level X: Sets the UASTC HDR compressor's level. Valid range is [0,4] - higher=slower but higher quality. HDR default=1.\n" |
| " Level 0=fastest/lowest quality, 3=highest practical setting, 4=exhaustive\n" |
| " -hdr_ldr_no_srgb_to_linear: If specified, LDR images will NOT be converted to normalized linear light (via a sRGB->Linear conversion) before compressing as HDR.\n" |
| " -hdr_uber_mode: Allow the encoder to try varying the selectors more for slightly higher quality. This may negatively impact BC6H quality, however.\n" |
| " -hdr_favor_astc: By default the HDR encoder tries to strike a balance or even slightly favor BC6H quality. If this option is specified, ASTC HDR quality is favored instead.\n" |
| "\n" |
| "More options:\n" |
| " -test: Run an automated LDR ETC1S/UASTC encoding and transcoding test. Returns EXIT_FAILURE if any failures\n" |

| " -y_flip: Flip input images vertically before compression\n" |
| " -normal_map: Tunes codec parameters for better quality on normal maps (linear colorspace metrics, linear mipmap filtering, no selector RDO, no sRGB)\n" |
| " -no_alpha: Always output non-alpha basis files, even if one or more inputs has alpha\n" |

| " -separate_rg_to_color_alpha: Separate input R and G channels to RGB and A (for tangent space XY normal maps)\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" |
| " -framerate X: Set framerate in .basis header to X/frames sec.\n" |
