Usually, image class was intended to be used for this purpose but unfortunately, its design was not very useful. In its most simple usage, Bitmap class just display a given BitMap. However, you can also tell it to do automatic color remapping to match the current display context and you can define a transparent color to make the BitMap appear on any background. Bitmap.mui/MUIA_Bitmap_Bitmap NAME MUIA_Bitmap_Bitmap -- (V8 ) [ISG], struct BitMap * FUNCTION This attribute specifies a pointer to a struct BitMap. Note that specifying only a BitMap isn't enough, you have to tell MUI about the pixel width and height with MUIA_Bitmap_Width and MUIA_Bitmap_Height too. SEE ALSO MUIA_Bitmap_Width, MUIA_Bitmap_Height, MUIA_Bitmap_Transparent, MUIA_Bitmap_SourceColors, MUIA_Bitmap_MappingTable Bitmap.mui/MUIA_Bitmap_Height NAME MUIA_Bitmap_Height -- (V8 ) [ISG], LONG FUNCTION Define the pixel height of the BitMap. Note: By default, the bitmap object has a minimum size of 1 pixel and an unlimited maxium size. If the space is too small to hold your BitMap, it will be clipped. Usually, you will use MUIA_FixWidth and MUIA_FixHeight with BitMap objects to make them always exactly as big as the bitmap. SEE ALSO MUIA_Bitmap_Bitmap, MUIA_Bitmap_Width, MUIA_Bitmap_Transparent, MUIA_Bitmap_SourceColors, MUIA_Bitmap_MappingTable Bitmap.mui/MUIA_Bitmap_MappingTable NAME MUIA_Bitmap_MappingTable -- (V8 ) [ISG], UBYTE * FUNCTION Address of an array of UBYTEs, one for each color of the source BitMap. MUI will remap the BitMap according to the contents of the array. Since MUI applications usually don't know about their display environment, this tag is rarely used. Instead, MUIA_Bitmap_SourceColors can be used to allow context sensitive color remapping. SEE ALSO MUIA_Bitmap_Bitmap, MUIA_Bitmap_Height, MUIA_Bitmap_Width, MUIA_Bitmap_Transparent Bitmap.mui/MUIA_Bitmap_SourceColors NAME MUIA_Bitmap_SourceColors -- (V8 ) [ISG], ULONG * FUNCTION This attribute defines the color palette of the source BitMap. If specified, MUI will try to locate these colors on the current screen and remap the BitMap accordingly. You can e.g. specify some great looking 8-color images for several buttons of your application and MUI will ensure they look fine even on 4-color screens or on screens with completely different colors. When running Kickstart V39 or higher, MUI will use ObtainBestPen() to find or create your colors. Below V39, a simple color-map search is performed to find the best matching entry, but no colors will be changed. The source palette is specified with an array of ULONGs, three entries per color, 32bits per gun. EXAMPLE /* MagicWB-like palette for an 8-color image */ const ULONG aboutlogo_colors[24] = { 0xaaaaaaaa,0xaaaaaaaa,0xa0a0a0a0, 0x00000000,0x00000000,0x00000000, 0xffffffff,0xffffffff,0xffffffff, 0x66666666,0x88888888,0xbbbbbbbb, 0x99999999,0x99999999,0x99999999, 0xbbbbbbbb,0xbbbbbbbb,0xbbbbbbbb, 0xbbbbbbbb,0xaaaaaaaa,0x99999999, 0xffffffff,0xbbbbbbbb,0xaaaaaaaa }; SEE ALSO MUIA_Bitmap_Bitmap, MUIA_Bitmap_Height, MUIA_Bitmap_Width, MUIA_Bitmap_MappingTable, MUIA_Bitmap_MappingTable Bitmap.mui/MUIA_Bitmap_Transparent NAME MUIA_Bitmap_Transparent -- (V8 ) [ISG], LONG FUNCTION If specified, MUI will consider this color of the BitMap to be transparent. A mask plane will be generated and used for blitting, the background will shine through.

Note: By default, the bitmap object has a minimum size of 1 pixel and an unlimited maxium size. If the space is too small to hold your BitMap, it will be clipped. Usually, you will use MUIA_FixWidth and MUIA_FixHeight with BitMap objects to make them always exactly as big as the bitmap.
