Top Previous Next |
The DTWAIN_SetPixelType function sets the current Pixel Type (Color) and Bit Depth (Bits Per Pixel) that will be used when acquiring an image.
DTWAIN_BOOL DTWAIN_SetPixelType (
Parameters Source An open TWAIN Source.
PixelType Current pixel type.
BitDepth Current bit depth or DTWAIN_DEFAULT.
bSetCurrent Determines whether to set the current or default pixel/bit depth.
Return Values The return value is TRUE if successful. Otherwise FALSE is returned.
Comments The DTWAIN_SetPixelType function sets the current pixel color and bit depth for the next acquired image. On successful return of DTWAIN_SetPixelType, the PixelType is the pixel type, and BitDepth is the bit depth or DTWAIN_DEFAULT if the default bit depth is to be used.
If bSetCurrent is TRUE, the current pixel type is set. Note that the bit depth current/default set type is determined by the BitDepth argument, not by bSetCurrent.
The pixel type can be any of the Pixel Type Constants. The bit depth is a LONG number denoting the number of bits per pixel.
TWAIN State Transitions The Source must be in State 4. or higher
Prerequisite Function Call(s)
