Sets the bits per pixel to be used when transferring images from the current TWAIN source.
L_LTTWN_API L_INT L_TwainSetImageBitsPerPixel(hSession, nBitsPerPixel)
Handle to an existing TWAIN session. This handle is obtained by calling the L_TwainInitSession or L_TwainInitSession2 function.
Number of bits per pixel to set. For more information on possible values, refer to the TWAIN specification.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function internally sets the bits per pixel capability ICAP_BITDEPTH. For more information on this capability, refer to the TWAIN specification.
To obtain the current bits per pixel value, call the L_TwainGetImageBitsPerPixel function
This function should be called after calling the L_TwainStartCapsNeg function and before calling the L_TwainEndCapsNeg function.
For an example, refer to L_TwainSetImageUnit.
