#include "l_bitmap.h"
L_LTIMGSFX_API L_INT L_BumpMapBitmap(pBitmapDst, pBumpBitmap, pBumpData)
pBITMAPHANDLE pBitmapDst; |
/* pointer to the bitmap handle */ |
pBITMAPHANDLE pBumpBitmap; |
/* pointer to the bitmap handle */ |
pBUMPDATA pBumpData; |
/* pointer to a structure */ |
Adds a three-dimensional texture pattern created by applying the bump image to the destination image.
Parameter |
Description |
pBitmapDst |
Pointer to the bitmap handle referencing the destination bitmap. This bitmap will be updated by the function. |
pBumpBitmap |
Pointer to the bitmap handle referencing the Bump bitmap. |
pBumpData |
Pointer to a BUMPDATA structure that contains information about the bump parameter. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
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 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.
