| Name | Type | Description |
|---|---|---|
| biSize | WORD | Total length of this struct, in bytes. |
| biWidth | LONG | Number of pixels in each raster (row) of the bitmap. |
| biHeight | LONG | Number of rasters (rows) in the bitmap. |
| biPlanes | WORD | Number of bit planes. Always = 1. |
| biBitCount | WORD | Number of bits per pixel (bit depth): 1, 4, 8, 9-16-bit gray level, or 24, 32. |
| biCompression | DWORD | Type of compression, or 0 (IG_BI_RGB) if bitmap not compressed. IG_BI_RGB, IG_BI_RLE, IG_BI_CMYK. |
| biSizeImage | DWORD | Total number of bytes in bitmap (necessary if bitmap is compressed; may be 0 if bitmap is IG_BI_RGB). |
| biXPelsPerMeter | LONG | Pixels per meter horizontally if known (else 0). |
| biYPelsPerMeter | LONG | Rows per meter vertically if known (else 0). |
| biClrUsed | DWORD | Number of entries in the color palette that are actually used. (The number of unique pixel values that occur.) If 0, it is assumed all palette entries are used. |
| biClrImportant | DWORD | Number of palette entries considered important. If 0, all are important. |
