virtual L_INT LBitmapBase::IsGrayScale()
Returns an indicator that shows the kind of grayscale palette, if any, that a bitmap has.
GRAY_NO |
[0] Not grayscale. |
GRAY_ORDEREDNORMAL |
[1] Normally ordered grayscale (dark to light). |
GRAY_ORDEREDINVERSE |
[2] Reverse ordered grayscale (light to dark). |
GRAY_NOTORDERED |

Grayscale images can be 1-bit, 4-bit, 8-bit, 12-bit or 16-bit. With a 1-bit image, you can use this function to check for inversion (for example, white lines on a black background) caused by an inverted palette.
Support for 12 and 16-bit grayscale images is only available in the Document/Medical toolkits.
