Extract pages Leave feedback

GroupDocs.Merger allows to extract pages from source document. The result is a new document that contains only specified pages from the source document.

Warning

Specify at least one page number. Calling ExtractPages without page numbers (for example, with new ExtractOptions()) throws GroupDocsMergerException (“There are no page numbers to extract.”).

Here are the steps to extract document pages:

• Initialize ExtractOptions class with page numbers that should appear in the resultant document;
• Instantiate Merger object with source document path or stream;
• Call ExtractPages method and pass ExtractOptions object to it;
• Call Save method specifying file path to save resultant document.

The following code sample demonstrates how to extract document pages by specifying exact page numbers:

string filePath = @"c:\sample.pdf";
string filePathOut = @"c:\output\result.pdf";

ExtractOptions extractOptions = new ExtractOptions(new int[] { 1, 4 }); // Resultant document will contain pages 1 and 4

using (Merger merger = new Merger(filePath))
{
    merger.ExtractPages(extractOptions);
    merger.Save(filePathOut);
}

The following code sample demonstrates how to extract document pages by specifying page numbers range:

string filePath = @"c:\sample.pdf";
string filePathOut = @"c:\output\result.pdf";

ExtractOptions extractOptions = new ExtractOptions(1, 3, RangeMode.EvenPages); // Resultant document will contain page 2
using (Merger merger = new Merger(filePath))
{
	merger.ExtractPages(extractOptions);
    merger.Save(filePathOut);
