virtual L_INT LBitmap::ConvertUnsignedToSigned(uFlags)
Converts an unsigned bitmap to signed.
Flag that indicates how to process bits outside the low bit to high bit range. Possible values are:
|PROCESS_RANGE_ONLY||[0x0001] Shift data by adding half the range to each pixel without changing bits outside the (LowBit-HighBit) range.|
|PROCESS_OUTSIDE_RANGE||[0x0002] Shift data by adding half the range to each pixel and set to zero all bits outside the (LowBit-HighBit) range.|
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function updates MaxVal and MinVal different values with new values that consider bitmap new sign. Also LBitmapBase::IsPixelsSigned() value will be set to one.
This function supports 12 and 16-bit grayscale images. Support for 12 and 16-bit grayscale images is available only in the Document/Medical toolkits.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
