L_PicturizeBitmapSingle

#include "l_bitmap.h"

L_LTIMGEFX_API L_INT L_PicturizeBitmapSingle(pBitmap, pThumbBitmap, uCellWidth, uCellHeight, uLightnessFact, uFlags)

pBITMAPHANDLE pBitmap;	pointer to the bitmap handle
pBITMAPHANDLE pThumbBitmap;	pointer to the thumbnail bitmap handle
L_UINT uCellWidth;	thumbnail width
L_UINT uCellHeight;	thumbnail height
L_UINT uLightnessFact;	lightening or darkening value
L_UINT32 uFlags;	flags

Picturizes the specified bitmap using the specified thumbnail image.

Parameter	Description
pBitmap	Pointer to the bitmap handle that references the bitmap to be picturized.
pThumbBitmap	Pointer to the bitmap handle that references the bitmap used to create the thumbnail.
uCellWidth	Width of the thumbnail bitmap.
uCellHeight	Height of the thumbnail bitmap.
uLightnessFact	Value that represents how much to lighten the thumbnail bitmap. Valid values are between 0 and 1000. This value is divided internally by 1000. Values between 0 and 499 darken the image. Values between 500 and 1000 lighten the image.
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.

The image, or selected region, is broken down into rectangles of size uCellWidth x uCellHeight. For each rectangle, the thumbnail image is corrected to approximate that rectangle, and inserted in the original image. Note that every rectangle is replaced with the same image.

The uLightnessFact parameter can be used to change the lightness of the big image by changing the lightness of each rectangle.

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Supportfor 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 picturize it with the same bitmap.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT PicturizeBitmapSingleExample(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("IMAGE1.CMP")), &LeadBitmap, sizeof(BITMAPHANDLE), 0, ORDER_BGR, NULL, NULL); 
   if(nRet !=SUCCESS) 
      return nRet; 
   /*Picturize the bitmap */ 
   nRet = L_PicturizeBitmapSingle(&LeadBitmap, &LeadBitmap,20,15,200, 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; 
}
