Insert(RasterImage) Method

Summary

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

Syntax

C++/CLI

Python

public void Insert( 
   RasterImage image 
)

public: 
void Insert(  
   RasterImage^ image 
)

def Insert(self,image):

Parameters

image
Image to be inserted in the PDF file.

Remarks

This method does not use MRC segmentation on the image being inserted into the PDF file. Use the SetCompression method to specify the compression for the segments. For more information, refer to Creating a Compressed PDF File.

Example

This example inserts an image into a PDF document by using user Segments.
