#include "ltwrappr.h"

#include "LTCPDFComp.h"

L_INT LPDFCompressor::InsertNormal(pBitmap)

pointer to an LBitmapBase object

Compresses the specified image, without segmenting it, and inserts the image in the PDF file in memory.

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

Returns

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.

Example

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