LPDFCompressor::InsertMRC

#include "LTCPDFComp.h"
L_INT LPDFCompressor::InsertMRC(pBitmap, pPDFOptions)
LBitmapBase* pBitmap; |
/* pointer to an LBitmapBase object */ |
LPPDFCOMPOPTIONS pPDFOptions; |
/* pointer to the PDFCOMPOPTIONS structure */ |
Segments the specified image using MRC segmentation, compresses it, and inserts the image in the PDF file in memory.
Parameter |
Description |
pBitmap |
Pointer to the bitmap object that references the image to be inserted in the PDF file. |
pPDFOptions |
Pointer to the PDFCOMPOPTIONS structure that contains options used to write the image to the PDF file in memory. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
To insert the bitmap without using MRC segmentation, use LPDFCompressor::InsertNormal.
This function calls the LPDFCompressor::ImageCallBack, if LBase::EnableCallBack was set to TRUE, to allow the user to accept or reject the addition of any segment to the PDF document.

Example
This example inserts an image in a pdf document and uses MRC segmentation to segment this image. In this sample we don't need to add a background segment.
class LPDFCompressorKidIM : public LPDFCompressor { protected: L_INT ImageCallBack(L_INT nPage, LPSEGMENTINFO pSegment) { UNREFERENCED_PARAMETER(nPage); if(pSegment->uSegmentType == SEGTYPE_BACKGROUND) return FAILURE; else return SUCCESS; } }; L_INT LPDFCompressor__InsertMRCExample(HWND hwnd) { LPDFCompressorKidIM pdf ; L_INT nRet; LBitmap LEADBitmap; PDFCOMPOPTIONS PDFOptions; PDFCOMPRESSION pdfComp; memset(&PDFOptions,0,sizeof(&PDFOptions)); pdf.EnableCallBack (TRUE); nRet = pdf.Init (); if (nRet != SUCCESS) { MessageBox(hwnd, TEXT("Couldn't initialize pdf compressor"), TEXT("Error"), MB_OK) ; return nRet; } pdfComp.uStructSize = sizeof( pdfComp ); pdfComp.dwFlags = PDFCOMP_1BITCOMPTYPE_ENABLED | PDFCOMP_2BITCOMPTYPE_ENABLED | PDFCOMP_PICTURECOMPTYPE_ENABLED; pdfComp.comp1Bit = PDFCOMP_1BITCOMPTYPE_JBIG2; pdfComp.comp2Bit = PDFCOMP_2BITCOMPTYPE_ZIP; pdfComp.compPicture = PDFCOMP_PICTURECOMPTYPE_JPEG; pdfComp.nQFactor =50; nRet = pdf.SetCompression ( &pdfComp ); if(nRet != SUCCESS) { pdf.Free (); return nRet; } PDFOptions.uStructSize = sizeof(PDFCOMPOPTIONS); PDFOptions. dwFlags = PDFCOMP_FAVOR_ONEBIT | PDFCOMP_WITH_BACKGROUND; PDFOptions.imageQuality = PDFCOMP_IMAGEQUALITY_USER; PDFOptions.outputQuality = PDFCOMP_OUTPUTQUALITY_USER; PDFOptions.uCleanSize = 7; PDFOptions.uBackGroundThreshold = 15; PDFOptions.uCombineThreshold = 100; PDFOptions.uSegmentQuality = 50; PDFOptions.uColorThreshold = 25; nRet = LEADBitmap.Load(TEXT("C:\\Program Files\\LEAD Technologies, Inc\\LEADTOOLS 15.0\\Images\\IMAGE4.CMP")); if(nRet != SUCCESS) { MessageBox(hwnd, TEXT("Failed to load source image \"C:\\Program Files\\LEAD Technologies, Inc\\LEADTOOLS 15.0\\Images\\IMAGE4.CMP\""), TEXT("Error"), MB_OK); pdf.Free(); return nRet; } nRet = pdf.InsertMRC(&LEADBitmap, &PDFOptions); if(nRet != SUCCESS) return nRet; nRet = pdf.Write (TEXT("C:\\Program Files\\LEAD Technologies, Inc\\LEADTOOLS 15.0\\Images\\Output(InsertMRC).pdf")); if (nRet ==SUCCESS) MessageBox( hwnd, TEXT("Result saved to C:\\Program Files\\LEAD Technologies, Inc\\LEADTOOLS 15.0\\Images\\Output(InsertMRC).pdf"), TEXT("Error"), MB_OK); else { MessageBox( hwnd, TEXT("Failed to save result"), TEXT("Error"), MB_OK); return nRet; } pdf.Free (); return SUCCESS; }
