81464a6d6b Changing the ETC1S->BC4 and ETC1S->ETC2 EAC transcoders so they convert from the source red channel, not source green. Source red makes more sense when transcoding to BC4/BC5, especially when the source texture only has color slices. BC4 is red, and BC5 is red/green. This change makes no difference if the source texture slices are grayscale. Rich Geldreich 2019-05-10 22:04:40 -07:00

c7e14a97fa - Fixing minor block artifacts on pure 2 color B&W blocks when transcoding to BC1/BC7. This was caused by the ETC1S blocks using extreme ETC1S settings: codetable 7 (the one with the largest intensity deltas), using blocks with selectors that took up the full range (0-3), but the blocks only actually used the two outlier colors (0 and 3 only). The ETC1S->BC1/BC7 table based format conversion system doesn't realize that only the outlie colors were going to be used (i.e. not all 4 colors, just the outer 2), and so the quality of the transcoded block suffered because pure black could not be mapped. In BC7 mode, we now switch to pure BCT (block truncation coding) for any blocks with <= 2 unique colors, independent of their selectors. - Adding -csv_file option, to generate .csv files for mass benchmarking/testing - Adding -no_ktx option, to avoid writing large .KTX files while unpacking - Fixing printf() format issue when one of the -multifile options wasn't correct Rebuilt compiled javascript transcoder Rich Geldreich 2019-05-09 10:44:38 -07:00

130eb9f115 Major compression performance/quality improvements, for a 15-35% or so decrease in file size for the same Y PSNR/SSIM. The basis file format has changed due to these optimizations. Increasing the max codebook size to 16K vs. 8K, for a major increase in the max achievable quality. Adding exception catching to command line tool. Enabling debug iterators on MSVC. Refining command line options, adding "-individual" flag to create multiple .basis files (vs. a texture array). Changing default colorspace to sRGB, because that's probably the best default. -linear disables this and uses linear colorspace metrics. PNG reader in 32-bit builds checks the size of the file before loading to avoid out of memory exceptions. Rich Geldreich 2019-05-07 15:52:29 -07:00

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.
