LBitmapBase::IsGrayScale

#include "ltwrappr.h"

virtual L_INT LBitmapBase::IsGrayScale()

Returns an indicator that shows the kind of grayscale palette, if any, that a bitmap has.

Returns

Comments

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.
