ABCpdf .NET PDF Component Documentation - XTransform Rotate Function. Rotate about a locked anchor point (angle in degrees).

Rotate Function

Rotate about a locked anchor point (angle in degrees).

Syntax

[C#]
void Rotate(double angle, double anchorX, double anchorY)

Params

Name	Description
angle	The angle to rotate in degrees.
anchorX	The horizontal coordinate about which the rotation should be applied.
anchorY	The vertical coordinate about which the rotation should be applied.

Notes

This method rotates the world space about a locked anchor point. The angle is specified in degrees anti-clockwise.

Example

Here we add a number of chunks of text rotated at different angles about the middle of the document.

using var doc = new Doc();
doc.FontSize = 48;
doc.TextStyle.Indent = 48;
for (int i = 1; i <= 8; i++) {
  int angle = i * 45;
  doc.Pos.String = "302 396";
  doc.Transform.Reset();
  doc.Transform.Rotate(angle, 302, 396);
  doc.AddText($"Rotated {angle}");
}
doc.Save("rotate.pdf");
