L_LTIMGEFX_API L_INT L_OilifyBitmap(pBitmap, uDim, uFlags)

pBITMAPHANDLE pBitmap;

pointer to the bitmap handle

L_UINT uDim;

dimensions of the neighborhood (uDim x uDim), in pixels

L_UINT32 uFlags;

flags

Applies an oil-painting effect to the bitmap.

Parameter

Description

pBitmap

Pointer to the bitmap handle that references the bitmap to be affected.

uDim

Dimensions of the neighborhood used for filtering (uDim x uDim), in pixels.

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.

You control the effect by specifying the size of the neighborhood that is used for calculating the pixel value. For example, for 8x8, pass 8 in the uDim parameter. You increase the size of the neighborhood in order to decrease the amount of detail in the resulting image.

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

This example loads a bitmap and oilifies it.

L_INT OilifyBitmapExample(L_VOID) 
{ 
   L_INT nRet; 
   BITMAPHANDLE LeadBitmap;   /* Bitmap handle to hold the loaded image. */ 
   /* Load the bitmap, keeping the bits per pixel of the file */ 
   nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image2.jpg")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
   if(nRet !=SUCCESS) 
      return nRet; 
   /* Oilify with neighborhood of 5 x 5 */ 
   nRet = L_OilifyBitmap(&LeadBitmap, 5 , 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; 
}
