Syntax

#include "ltwrappr.h"
#include "LTCPDFComp.h"

L_INT LPDFCompressor::InsertNormal(pBitmap)

Parameters

LBitmapBase * pBitmap

Pointer to the bitmap handle that references the image to be inserted in the PDF document.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

To segment an image using MRC segmentation, compress it, and insert the bitmap to the PDF file in memory, call LPDFCompressor::InsertMRC.

Required DLLs and Libraries

LCMRC
LCPDF
LCENC
LCZIB
LTSGM
For a listing of the exact DLLs and Libraries needed, based on the toolkit version, refer to Files To Be Included With Your Application.

Example

This example inserts an image in a pdf document without using MRC segmentation.

class LPDFCompressorKidIN : public LPDFCompressor  
{ 
protected:  
   L_INT ImageCallBack(L_INT nPage, LPSEGMENTINFO pSegment)  
   { 
      UNREFERENCED_PARAMETER(nPage); 
 
      if(pSegment->uSegmentType == SEGTYPE_BACKGROUND) 
         return FAILURE; 
      else 
         return SUCCESS;  
   } 
};
