Add text and images to PDF pages in C++

Use PdfFileMend to place images and formatted text on PDF pages and configure compositing or word wrapping.

In AddImage01 through AddImage04, inputFile is an image path and the function creates a new PDF page. Text examples accept a PDF path. AddText03 appends three pages before adding text to pages 1 and 3.

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.

PdfFileMend workflows

Add an image to a new PDF

Create a new one-page PDF and add inputFile as an image in the rectangle (10, 650, 110, 750).

  1. Create PdfFileMend.
  2. Create or open the Document and prepare its pages as shown.
  3. Bind the PDF input with Facade::BindPdf().
  4. Place the image with PdfFileMend::AddImage().
  5. Save the resulting PDF with PdfFileMend::Save().
