James Jackson-South	2fcba54a3e	Faster Jpeg Huffman Decoding. (#894 ) * Read from underlying stream less often * Update benchmark dependencies * Experimental mango port Currently broken * Populate table, 64byte buffer Still broken. * Baseline, non RST works * 15/19 baseline tests pass now. * Optimize position change. * 18/19 pass * 19/19 baseline decoded * Can now decode all images. * Now faster and much cleaner. * Cleanup * Fix reader, update benchmarks * Update dependencies * Remove unused method * No need to clean initial buffer * Remove bounds check on ReadByte() * Refactor from feedback	7 years ago
James Jackson-South	0a78af5bdb	Cleanup General Convolution (#887 ) * Remove multiple premultiplication. * Use in DenseMatrix everywhere. * Make private * Dont convert vector row on first pass * Remove incorrectly assigned alpha. * Remove boxing. * Use correct min row. * Reorder parameters * Correctly handle alpha component. * Update tests * Use dedicated methods over branching.	7 years ago

Additional fields for V4 are zero anyway. * added parsing of special case for 56 bytes headers * using the alpha mask in ReadRgb32BitFields() when its present * added support for bitmasks greater then 8 bits per channel * using MagickReferenceDecoder reference decoder for the test with 10 bits pixel masks * changed bitmap constants to hex * added enum for the bitmap info header type * added support for 52 bytes header (same as 56 bytes without the alpha mask) * clarified comment with difference between imagesharp and magick decoder for Rgba321010102 * BmpEncoder now writes a V4 info header and uses BITFIELDS compression * workaround for issue that the decoder does not decode the alpha channel correctly: For V3 bitmaps, the alpha channel will be ignored during encoding * Fix #732	7 years ago
