Jorge Rodriguez e05ebdbf1e My guess is people who care about premultiply also care about color space. ago%!(EXTRA string=11 years)
Jorge Rodriguez d75488b0e8 Do the multiply inline, it should be a tad faster and not corrupt our data. ago%!(EXTRA string=11 years)
Jorge Rodriguez 13acfca829 I had the whole premultiply thing backwards. ago%!(EXTRA string=11 years)
Jorge Rodriguez 21c7c8f5d9 Another stab at the api, offering classes of functions for different common tasks. ago%!(EXTRA string=11 years)
Jorge Rodriguez 8063ea0952 Specify a channel as having premultiplied alpha and use it to un-premultiply all other channels before resampling. ago%!(EXTRA string=11 years)
Jorge Rodriguez a32fa8b4df This to-do item done. ago%!(EXTRA string=11 years)
Jorge Rodriguez daf325dc03 Sub pixel source area test cases. No problems. ago%!(EXTRA string=11 years)
Jorge Rodriguez aae1c7ca41 ZOOM AND ENHANCE! ago%!(EXTRA string=11 years)
Jorge Rodriguez 1b2d104e00 Some error conditions. ago%!(EXTRA string=11 years)
Jorge Rodriguez 35cb95b803 Allow for specifying a sub-region of the source image to use. Downsampling only, currently. ago%!(EXTRA string=11 years)
Jorge Rodriguez 52ac93225a C<99 ports ago%!(EXTRA string=11 years)
Jorge Rodriguez fdc979e48b Some minor ports for Linux. No idea how it worked at all in Windows with STB_RESIZE_IMPLEMENTATION instead of STB_RESAMPLE_IMPLEMENTATION. ago%!(EXTRA string=11 years)
Jorge Rodriguez c5de2f3298 Test channels. ago%!(EXTRA string=11 years)
Jorge Rodriguez 985ac75251 When doing a perfect po2 nearest neighbor downsample don't allow -0.5 and 0.5 to both contribute to a texel or you'll get a double tap. ago%!(EXTRA string=11 years)
Jorge Rodriguez c2449acc3e Tests for edge behavior ago%!(EXTRA string=11 years)
Jorge Rodriguez 59cb71ea18 Fix float conversion. ago%!(EXTRA string=11 years)
Jorge Rodriguez 6625259959 Try to keep integer precision by briefly casting to double while decoding and encoding. ago%!(EXTRA string=11 years)
Jorge Rodriguez 11897fbf96 More fixing shorts. ago%!(EXTRA string=11 years)
Jorge Rodriguez 1fcbe0daaf Fix shorts. Add test cases for shorts. ago%!(EXTRA string=11 years)
Jorge Rodriguez 7ead9a748d Fix. Ring buffers are a height value. ago%!(EXTRA string=11 years)
Jorge Rodriguez 043fa28c11 Same deal with height. ago%!(EXTRA string=11 years)
Jorge Rodriguez ebe0473d8b Add a test suite to do a bunch of different resizes to find problems. One problem found was an incorrect calculation of texel support how many margin texels needed when downsampling. When downsampling we need to spread out the support of each contributing texel, so to compensate you need more margin texels. ago%!(EXTRA string=11 years)
Jorge Rodriguez 68f93b72d5 Update documentation and add helper functions. ago%!(EXTRA string=11 years)
Jorge Rodriguez 5b40906271 My perf testing code. ago%!(EXTRA string=11 years)
Jorge Rodriguez d96c97298c This is still faster than the function pointer solution, and neater. ago%!(EXTRA string=11 years)
Jorge Rodriguez 3a3e06029e This is definitely faster than the function pointer solution. ago%!(EXTRA string=11 years)
Jorge Rodriguez 9bd5abb52d Both versions run within the margin of error on my machine so we'll go with the simpler one. ago%!(EXTRA string=11 years)
Jorge Rodriguez 5dff80ed31 Trying some different strategies for optimizing the decoder. The code in #ifdef 1 is slightly faster by my measurements, but a whole lot uglier. ago%!(EXTRA string=11 years)
Jorge Rodriguez 05f775e977 Merge branch 'master' of https://github.com/BSVino/stb ago%!(EXTRA string=11 years)
Jorge Rodriguez 1fcf30ada0 Fix a math error. ago%!(EXTRA string=11 years)
Jorge Rodriguez e2ac4f6505 More resample ideas ago%!(EXTRA string=11 years)
Jorge Rodriguez ef3a460ec4 Some better looking horners save another multiplication. ago%!(EXTRA string=11 years)
Jorge Rodriguez 7d47582578 Support for 16 and 32 bit integer images, and float images. ago%!(EXTRA string=11 years)
Jorge Rodriguez 6c8cac0a66 Support for sRGB color space. ago%!(EXTRA string=11 years)
Jorge Rodriguez 41dc4c476c In some situations with certain filter kernels with negative values it's possible to generate valid results > 1.0, so saturate it before we write it to make sure it doesn't overflow. Also fix incorrect filter radius while downsampling. ago%!(EXTRA string=11 years)
Jorge Rodriguez af1ed58f51 Add wrap, fix reflect so it doesn't wrap. ago%!(EXTRA string=11 years)
Jorge Rodriguez 8723567439 Add edge reflect mode. ago%!(EXTRA string=11 years)
Jorge Rodriguez 6cd81d4dd5 Put the polynomials in horner form to save a multiplication. ago%!(EXTRA string=11 years)
Jorge Rodriguez fb2f8df5cc Add mitchell filter. ago%!(EXTRA string=11 years)
Jorge Rodriguez 69af963c42 Add catmull rom filter. Also, move the debug asserts for values <= 1 to the very end of the process. This will make these bugs a lot harder to find, but because some filter kernels have negative values it's possible for the buffers to have values > 1 up until the point where it's converted back to an int. ago%!(EXTRA string=11 years)
Jorge Rodriguez 12acf87eec When downsampling start the buffer loop at -filter_texel_margin to make sure that all contributors get their taps in at the ring buffer. ago%!(EXTRA string=11 years)
Jorge Rodriguez 155c71fb90 Reorder these loops because I think we get a cache win if we write the entire ring buffer entry at once. ago%!(EXTRA string=11 years)
Jorge Rodriguez 01fb58d6b4 Add a bicubic filter. ago%!(EXTRA string=11 years)
Jorge Rodriguez a95da9ee1d Unroll the multiply-add loops. At the cost of a function pointer dereference we get a whole lot of conditionals eliminated. Should be a solid win once the debug asserts are gone. ago%!(EXTRA string=11 years)
Jorge Rodriguez 7abd4ccf34 Support for filters with larger support. Initial support for edge behavior. ago%!(EXTRA string=11 years)
