# BMP Suite Reference Images

File | bpp | Comments | Reference
--- | --- | --- | ---
g01bw.bmp | 1 | black and white palette (#000000,#FFFFFF) |
g01wb.bmp | 1 | white and black palette (#FFFFFF,#000000). Should look the same as g01bw, not inverted. |
g01bg.bmp | 1 | blue and green palette (#4040FF,#40FF40) |
g01p1.bmp | 1 | 1-color (blue) palette (#4040FF) |
g04.bmp | 4 | basic 4bpp (16 color) image |
g04rle.bmp | 4 | RLE compressed. |
g04p4.bmp | 4 | 4-color grayscale palette |
g08.bmp | 8 | basic 8bpp (256 color) image |
g08p256.bmp | 8 | biClrUsed=256, biClrImportant=0 [=256] |
g08pi256.bmp | 8 | biClrUsed=256, biClrImportant=256 |
g08pi64.bmp | 8 | biClrUsed=256, biClrImportant=64. It's barely possible that some sophisticated viewers may display this image in grayscale, if there are a limited number of colors available. |
g08rle.bmp | 8 | RLE compressed. |
g08os2.bmp | 8 | OS/2-style bitmap. This is an obsolete variety of BMP that is still encountered sometimes. It has 3-byte palette entries (instead of 4), and 16-bit width/height fields (instead of 32). |
g08res22.bmp | 8 | resolution 7874x7874 pixels/meter (200x200 dpi) |
g08res11.bmp | 8 | resolution 3937x3937 pixels/meter (100x100 dpi) |
g08res21.bmp | 8 | resolution 7874x3937 pixels/meter (200x100 dpi). Some programs (e.g. Imaging for Windows) may display this image stretched vertically, which is the optimal thing to do if the program is primarily a viewer, rather than an editor. |
g08s0.bmp | 8 | bits size not given (set to 0). This is legal for uncompressed bitmaps. |
g08offs.bmp | 8 | bfOffBits in header not set to the usual value. There are 100 extra unused bytes between palette and bits. |
g08w126.bmp | 8 | size 126x63 (right and bottom slightly clipped) |
g08w125.bmp | 8 | size 125x62 |
g08w124.bmp | 8 | size 124x61 |
g08p64.bmp | 8 | 64-color grayscale palette |
g16def555.bmp | 16 | 15-bit color (1 bit wasted), biCompression=BI_RGB (no bitfields, defaults to 5-5-5) |
g16bf555.bmp | 16 | 15-bit color, biCompression=BI_BITFIELDS (bitfields indicate 5-5-5) |
g16bf565.bmp | 16 | 16-bit color, biCompression=BI_BITFIELDS (bitfields indicate 5-6-5) |
g24.bmp | 24 | 24-bit color (BGR) |
g32def.bmp | 32 | 24-bit color (8 bits wasted), biCompression=BI_RGB (no bitfields, defaults to BGRx) |
g32bf.bmp | 32 | 24-bit color (8 bits wasted), biCompression=BI_BITFIELDS (bitfields indicate BGRx) |
