4 a command-line tool for compressing and decompressing images using the ASTC
27 The encoder supports compression of low dynamic range (BMP, JPEG, PNG, TGA) and
31 The decoder supports decompression of ASTC or KTX format input images into low
40 compression time, and the Peak Signal-to-Noise Ratio (PSNR) between the input
45 The `astcenc` compressor supports generation of images for all three profiles
52 It also supports all of the ASTC block sizes and compression modes, allowing
53 content creators to use the full spectrum of quality-to-bitrate options ranging

64 Binaries are provided for 64-bit builds on Windows, macOS, and Linux.
71 For x86-64 we provide, in order of increasing performance:
73 * `astcenc-sse2` - uses SSE2
74 * `astcenc-sse4.1` - uses SSE4.1 and POPCNT
75 * `astcenc-avx2` - uses AVX2, SSE4.2, POPCNT, and F16C
77 The x86-64 SSE2 builds will work on all x86-64 machines, but it is the slowest
83 * `astcenc-neon` - uses NEON
91 * `x86_64` - uses the `astcenc-sse4.1` build defined above.
92 * `x86_64h` - uses the `astcenc-avx2` build defined above.
93 * `arm64` - uses the `astcenc-neon` build defined above.
125 Invoking `astcenc -help` gives an extensive help message, including usage
131 Compress an image using the `-cl` \ `-cs` \ `-ch` \ `-cH` modes. For example:
133 astcenc -cl example.png example.astc 6x6 -medium
135 This compresses `example.png` using the LDR color profile and a 6x6 block
136 footprint (3.56 bits/pixel). The `-medium` quality preset gives a reasonable
138 point for compression. The output is stored to a linear color space compressed
143 * `-cl` : use the linear LDR color profile.
144 * `-cs` : use the sRGB LDR color profile.
145 * `-ch` : use the HDR color profile, tuned for HDR RGB and LDR A.
146 * `-cH` : use the HDR color profile, tuned for HDR RGBA.
150 specify the `-decode_unorm8` flag. This will ensure that the compressor uses
155 Decompress an image using the `-dl` \ `-ds` \ `-dh` \ `-dH` modes. For example:
157 astcenc -dh example.astc example.tga
168 Review the compression quality using the `-tl` \ `-ts` \ `-th` \ `-tH` modes.
171 astcenc -tl example.png example.tga 5x5 -thorough
173 This is equivalent to using using the LDR color profile and a 5x5 block size
174 to compress the image, using the `-thorough` quality preset, and then
184 Efficient real-time graphics benefits from minimizing compressed texture size,
193 The compression speed can be controlled from `-fastest`, through `-fast`,
194 `-medium` and `-thorough`, up to `-exhaustive`. In general, the more time the
