Reflects the bitmap on an ocean surface.
Parameter | Description | |
pBitmap | Pointer to the bitmap handle that references the bitmap to reflect. | |
uAmplitude | Wave magnitude, in pixels. | |
uFrequency | Number of repeated waves. | |
bLowerTrnsp | Flag that indicates the transparency direction. Possible values are: | |
Value | Meaning | |
TRUE | Transparency increases as you move from the bottom of the bitmap to the top of the bitmap, line by line. | |
FALSE | Transparency increases as you move from the top of the bitmap to the bottom of the bitmap, line by line. | |
uFlags | Reserved for future use. Must be 0. |
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.
If the bitmap has a region, the effect will be applied on the region only.
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.
To update a status bar or detect a user interrupt during execution of this function, refer to L_SetStatusCallback.
To obtain this effect, the following settings were used with the function:
uAmplitude=15
uFrequency=20
bLowerTrnsp=TRUE
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.
