ValueMemberDescription
0x00000000Background The segment uses one color that represents the image background.
0x00000001OneBit The segment is a 1BPP image.
0x00000002OnBitBW The segment is a 1BPP black and white image.
0x00000003TwoBit The segment is a 2BPP image.
0x00000004TwoBitGray The segment is a 2BPP gray scale image.
0x00000005Gray The segment is a gray scale image.
0x00000006Picture The segment is a picture.
0x00000007TwoBitBW The segment is a 2BPP black and white image.
0x00000008OneColor The segment has only one color.
