Jason Nelson	48bac7b334	Update metadata names (#879 )	7 years ago
Brian Popow	892bba1ed1	Add support for Decoding BI_ALPHABITFIELDS (#832 ) * Adds support for BI_ALPHABITFIELDS * Fix for decoding bitmaps with a less than full sized palette	7 years ago
Brian Popow	637f76707b	Respecting fileHeader Offset, skipping bytes if necessary (#819 )	7 years ago
Brian Popow	b03d41bbb9	Adds support for OS/2 version 2 bitmaps (#813 ) * Added support for OS/2 version 2 bitmaps * throw NotSupportedException, if the file header type is not BM * renamed Os2v2 to Os2v2Size * Added BmpThrowHelper similar to the JpegThrowHelper	7 years ago
Brian Popow	1b9979c9ef	Added support for RLE4 encoded bitmaps (#812 )	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
