L_PlasmaFilterBitmap

Summary

Applies color patterns that blend into each other like plasma.

Syntax

#include "l_bitmap.h"

L_LTIMGSFX_API L_INT L_PlasmaFilterBitmap(pBitmap, pPlasmaInfo, uFlags)

Parameters

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle that references the bitmap on which to apply the effect.

pPLASMAINFO pPlasmaInfo

Pointer to a PLASMAINFO structure that contains information about the plasma effect.

Returns

Value	Meaning
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 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.

Example

The following example applies a diagonal plasma effect by adding and blending color patterns onto the given image

L_INT PlasmaFilterBitmapExample(L_VOID) 
{ 
   L_INT nRet; 
   PLASMAINFO PlasmaInfo; 
   BITMAPHANDLE LeadBitmap; 
 
   nRet = L_LoadBitmap(MAKE_IMAGE_PATH(TEXT("Image2.jpg")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
   if (nRet != SUCCESS) 
      return nRet; 
 
   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); 
   if (nRet != SUCCESS) 
      return nRet; 
 
   nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL); 
   if (nRet != SUCCESS) 
      return nRet; 
 
   //free bitmap 
   if (LeadBitmap.Flags.Allocated) 
      L_FreeBitmap(&LeadBitmap); 
 
   return SUCCESS;
