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