Namespace: DevExpress.Pdf
Assembly: DevExpress.Pdf.v19.2.Drawing.dll
Declaration
Remarks
The PdfGraphics class contains all graphics content that allows an application to draw on the document.
The PdfDocumentProcessor.CreateGraphics() method creates a new PdfGraphics object. Use the PdfGraphics class object to create an image (PdfGraphics.DrawImage), text (PdfGraphics.DrawString), and other graphic elements.
The PdfGraphics
class uses the world coordinate system. See the Coordinate Systems topic for more information on coordinate systems used in the PdfDocumentProcessor.
Refer to the PDF Graphics section for more information on available graphics.
