Configure PDF image and text stamps in C++

Use Stamp to create image, PDF-page, and text stamps with placement, rotation, transparency, and page selection.

These examples use Aspose::Pdf::Facades::Stamp. Supply the required image or stamp PDF file; the PDF-page sample uses page 1 of the stamp source.

The snippets are independent example functions with their SDK includes and example namespaces. Configure the Aspose.PDF for C++ SDK, supply the input resources referenced by the sample, and choose writable output paths. The examples retain the source field names, page indexes, coordinates, and options.

Stamp workflows
