PdfGraphics.RotateTransform(Single) Method

Rotates the coordinate system clockwise to the specified angle relative to its origin.

Namespace: DevExpress.Pdf

Assembly: DevExpress.Pdf.v23.2.Drawing.dll

NuGet Package: DevExpress.Pdf.Drawing


public void RotateTransform(
    float degree


Name Type Description
degree Single

Angle of rotation in degrees.


This method multiplies the transformation matrix of the PdfGraphics object by a rotation matrix. Elements of the rotation matrix are derived from the degree parameter.


Coordinate system transformations (e.g., system rotation) are not taken into account for the following methods:

The code sample below rotates the coordinate system and draws shapes in the initial and rotated coordinate systems.

Rotates the Coordinate System

using DevExpress.Pdf;
using System.Drawing;

using (PdfDocumentProcessor processor = new PdfDocumentProcessor())
    PdfPage page = processor.AddNewPage(PdfPaperSize.A4);
        using (PdfGraphics graphics = processor.CreateGraphics())
            // Draw a green rectangle.
            using (var brush = new SolidBrush(Color.Green))
                graphics.FillRectangle(brush, new RectangleF(0, 0, 300, 200));

            // Rotate the coordinate system clockwise by 90 degrees.

            // Draw a blue rectangle in the rotated coordinate system.
            using (var brush = new SolidBrush(Color.Blue))
                graphics.FillRectangle(brush, new RectangleF(0, -350, 300, -200));

            // Add graphics content to the document page.
            graphics.AddToPageForeground(page, 72, 72);
