#include "l_bitmap.h"
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.
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.
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:
Member | 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 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
Win32, x64.
The following example applies a diagonal plasma effect by adding and blending color patterns onto the given image
