Members
wStructSize
Size, in bytes, of the structure.
wImageFlags
Image flags. This member can be a combination of one (and only one) color format value and other attribute values.
The color format can be one of these values:
| SO_BGRCOLOR | Pixel values are RGB color values (24-bit only); bytes are stored consecutively in the order B,G,R. |
| SO_BLACKANDWHITE | Pixels are black or white (1 bit per pixel only). |
| SO_COLORPALETTE | Pixel values are indexes into the color palette for the bitmap. |
| SO_GRAYSCALE | Pixel values are gray scale values. |
| SO_RGBCOLOR | Pixel values are RGB color values (24-bit only); bytes are stored consecutively in the order R,G,B. |
Other attributes can be a combination of these values:
| SO_BOTTOMTOTOP | The image is provided in scan lines from the bottom up. The default is top to bottom. |
| SO_WHITEZERO | For gray scale images and black and white images only, a pixel with a value of zero is a white pixel, and increasing pixel values become darker. By default, a value of zero is defined as a black pixel with increasing values becoming lighter. |
wImageWidth
Horizontal width, in pixels, of the image.
wImageLength
Vertical length, in pixels, of the image.
wTileWidth
Horizontal width, in pixels, of the tile.
wTileLength
Vertical length, in pixels, of the tile.
wBitsPerPixel
Number of consecutive bits that define the pixel color. The number is currently limited to 1, 4, 8, or 24.
wNPlanes
Color planes. This member must be 1.
wHDpi
Horizontal resolution, in pixels per inch, of the display on which the image originated. If the resolution is not known, this member can be zero.
wVDpi
Vertical resolution, in pixels per inch, of the display on which the image originated. If the resolution is not known, this member can be zero.
