#include "l_bitmap.h"
L_LTIMGSFX_API L_INT L_BumpMapBitmap(pBitmapDst, pBumpBitmap, pBumpData, uFlags)
Pointer to the bitmap handle referencing the destination bitmap. This bitmap will be updated by the function.
Pointer to the bitmap handle referencing the Bump bitmap.
Pointer to a BUMPDATA structure that contains information about the bump parameter.
Reserved for future use. Must be 0.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in the Document and Medical Imaging 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.
