L_LTIMGSFX_API L_INT L_PlasmaFilterBitmap(pBitmap, pPlasmaInfo, uFlags)
Applies color patterns that blend into each other like plasma.
Pointer to the bitmap handle that references the bitmap on which to apply the effect.
Pointer to a PLASMAINFO structure that contains information about the plasma effect.
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.
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 for the PLASMAINFO structure:
|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 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.
Required DLLs and Libraries
The following example applies a diagonal plasma effect by adding and blending color patterns onto the given image
nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image2.jpg")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL);
PlasmaInfo.uStructSize = sizeof(PLASMAINFO);
PlasmaInfo.uShift = 0;
PlasmaInfo.uOpacity = 50;
PlasmaInfo.uSize = 300;
PlasmaInfo.uFlags = PLSTYP_DIAGONAL | PLSCLR_RGB2;
nRet = L_PlasmaFilterBitmap (&LeadBitmap, &PlasmaInfo, 0);
nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL);
