L_PlasmaFilterBitmap

#include "l_bitmap.h"

L_LTIMGSFX_API L_INT L_PlasmaFilterBitmap(pBitmap, pPlasmaInfo, uFlags)

pBITMAPHANDLE pBitmap;

pointer to the bitmap handle

pPLASMAINFO pPlasmaInfo;

pointer to a structure

L_UINT32 uFlags;

flags

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.

uFlags

Reserved for future use. Must be 0.

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 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("ImageProcessingDemo\\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;
