Brian Popow	039eae6a99	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	7fda30d01d	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	fca697206a	Update metadata names (#879 )	7 years ago
Brian Popow	a2c4b2d5d8	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	07aa4f9316	Respecting fileHeader Offset, skipping bytes if necessary (#819 )	7 years ago
Brian Popow	2c62112017	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	0d68e6d09d	Added support for RLE4 encoded bitmaps (#812 )	7 years ago
Brian Popow	84ba4bbf0d	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
