Extract images from PDF in C++

Save an embedded image resource from a PDF page as JPEG using Aspose.PDF for C++.

Extract the first image from page 1

Export one image from the first page resource collection.

The input must have page 1 and at least one image resource on it. The example does not iterate over all images.

1. Open the input PDF as a Document.
2. Select page 1 and retrieve its first XImage resource.
3. Open a writable output stream.
4. Save the image using JPEG encoding.
5. Close the stream.
