L_LTIMGSFX_API L_INT L_PlasmaFilterBitmap(pBitmap, pPlasmaInfo)
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
pPLASMAINFO pPlasmaInfo; |
/* pointer to a structure */ |
Applies color patterns that blend into each other like plasma.
Parameter |
Description |
pBitmap |
Pointer to the bitmap handle that references the bitmap on which to apply the effect. |
pPlasmaInfo |
Pointer to a PLASMAINFO structure that contains information about the plasma effect. |
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.
As an example, suppose you call the L_PlasmaFilterBitmap function, using a uOpacity value of 0, which means that no image is to be used, and you use the following settings:
Parameter |
Value |
uShift |
0 |
uOpacity |
0 |
uSize |
1000 |
uFlags |
PLSTYP_RANDOM1 | PLSCLR_RGB2 |
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.
