image
Image to be inserted into the PDF file.
options
The PdfCompressorOptions structure that contains the options to be used to write the image to the PDF file.
image
Image to be inserted into the PDF file.
options
The PdfCompressorOptions structure that contains the options to be used to write the image to the PDF file.
Segments the specified image using Mixed Raster Content (MRC segmentation) and then compresses it and inserts it into the PDF file.

Syntax

Visual Basic (Declaration) 
Overloads Public Sub Insert( _
   ByVal image As RasterImage, _
   ByVal options As PdfCompressorOptions _
) 
Visual Basic (Usage)Copy Code
Dim instance As PdfCompressor
Dim image As RasterImage
Dim options As PdfCompressorOptions
 
instance.Insert(image, options)
C# 
public void Insert( 
   RasterImage image,
   PdfCompressorOptions options
)
C++/CLI 
public:
void Insert( 
   RasterImage image,
   PdfCompressorOptions options
) 

Parameters

image
Image to be inserted into the PDF file.
options
The PdfCompressorOptions structure that contains the options to be used to write the image to the PDF file.

Example

This example inserts an image to pdf document and uses the MRC to make a proper segment for this image.

Remarks

This method will use segmentation for inserting the image into the Pdf file. If the SetCompression method is used, the segments will be compressed using the compression options specified by the method's PdfCompressorCompressionTypes structure.
