Example

This example loads a bitmap and applies temperature bitmap filter.

L_INT TemperatureBitmapExample(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("cannon.jpg")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
    if(nRet != SUCCESS) 
        return nRet ; 
 
    /* Apply temperature bitmap filter */ 
    nRet = L_TemperatureBitmap(&LeadBitmap, 100, 0) ; 
 
    if(nRet !=SUCCESS) 
    { 
        //free bitmap 
        if(LeadBitmap.Flags.Allocated) 
            L_FreeBitmap(&LeadBitmap); 
        return nRet ; 
    } 
 
    nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.BMP")), &LeadBitmap, FILE_BMP, 24, 0, NULL) ; 
 
    //free bitmap 
    if(LeadBitmap.Flags.Allocated) 
        L_FreeBitmap(&LeadBitmap);
