Example
This example shows how to programmatically create a document with graphics using the PDF Document Creation API.
To generate a document using the Document Creation API:
- Create an empty document with no pages by calling one of the PdfDocumentProcessor.CreateEmptyDocument overload methods (e.g., using a file path).
- Create PDF graphics represented by an instance of the PdfGraphics class, calling the PdfDocumentProcessor.CreateGraphics method. To access PdfGraphics, you need to reference the DevExpress.Pdf.Drawing assembly.
- Draw the graphic content (e.g., an image, a string, lines, polygons) by calling the corresponding Draw method.
- Render a page with created graphics by calling the PdfDocumentProcessor.RenderNewPage method.
