Simon Cropp	564348631f	use var where apparent (#972 ) * use var where apparent * use var where apparent * should use Rgb24	7 years ago
Brian Popow	6fcfe09c38	Feature: Bitmap RLE undefined pixel handling (#927 ) * Add bitmap decoder option, how to treat skipped pixels for RLE * Refactored bitmap tests into smaller tests, instead of just one test which goes through all bitmap files * Add another adobe v3 header bitmap testcase * Using the constant from BmpConstants to Identify bitmaps * Bitmap decoder now can handle oversized palette's * Add test for invalid palette size * Renamed RleUndefinedPixelHandling to RleSkippedPixelHandling * Explicitly using SystemDrawingReferenceDecoder in some BitmapDecoder tests * Add test cases for unsupported bitmaps * Comparing RLE test images to reference decoder only on windows * Add test case for decoding winv4 fast path * Add another 8 Bit RLE test with magick reference decoder * Optimize RLE skipped pixel handling * Refactor RLE decoding to eliminate code duplication * Using MagickReferenceDecoder for the 8-Bit RLE test	7 years ago

Brian Popow	3431ad321e	Add support for encoding 8-bit bitmaps	7 years ago
Brian Popow	b0f6b73faa	Add support for encoding 16 bit per pixel bitmaps (#899 ) * Implemented encoding of 16 bits per pixel bitmaps * Add unit tests for 16 bit encoding and Bgra5551 conversion * Add additional Bgra5551 pixel conversion tests * Add Bgra5551 tests for Short2/4 and HalfVector2/4 * Use scaled vector conversion	7 years ago
Brian Popow	fcc7e5b257	Bitmap encoder writes V3 header as default (#889 ) * Bitmap encoder will now write a V3 header as default. Introduces a new encoder option `SupportTransparency`: With this option a V4 header will be written with BITFIELDS compression. * Add 4 and 16 bit images to the Identify test * Add some useful links for bitmap documentation * Add 32 bpp images to the Identify test * Added further information on what will change for the encoder, if SupportTransparency is used.	7 years ago
Jason Nelson	48bac7b334	Update metadata names (#879 )	7 years ago
Brian Popow	1996831667	Decoding Bitmaps with BITFIELDS masks (#796 ) * decoding bitmaps with Bitfields masks * added testcases for Bitfields bitmaps * added parsing of the complete bitmap V4 header to get the color masks infos for the BITFIELDS compression * writing now explicitly a Bitamp v3 header (40 bytes) * added test image for issue #735 * fixed rescaling 5-bit / 6-bit to 0 - 255 range * BitmapEncoder now writes BMP v4 header * using MemoryMarshal.Cast to simplify parsing v4 header * added testcases for bitmap v3, v4, v5 * Bitmap encoder writes again V3 header instead of V4. 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
