Extract Images from PDF C#

Contents
[ ]

Images are held in each page’s Resources collection’s Images collection. To extract a particular page, then get the image from the Images collection using the particular index of the image.

The image’s index returns an XImage object. This object provides a Save method which can be used to save the extracted image. The following code snippet shows how to extract images from a PDF file.

// For complete examples and data files, please go to https://github.com/aspose-pdf/Aspose.PDF-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_AsposePdf_Images();

// Open document
Document pdfDocument = new Document(dataDir+ "ExtractImages.pdf");

// Extract a particular image
XImage xImage = pdfDocument.Pages[1].Resources.Images[1];

FileStream outputImage = new FileStream(dataDir + "output.jpg", FileMode.Create);

// Save output image
xImage.Save(outputImage, ImageFormat.Jpeg);
outputImage.Close();

dataDir = dataDir + "ExtractImages_out.pdf";

// Save updated PDF file
pdfDocument.Save(dataDir);
