TCanvas.Pen Property

Specifies the kind of pen the canvas uses for drawing lines and outlining shapes.

Pascal

property Pen: TPen;

C++

__property TPen Pen;

Description

Set Pen to specify the pen to use for drawing lines and outlining shapes in the image. The value of Pen is a TPen object. Set the properties of the TPen object to specify the color, style, width, and mode of the pen.

Note: Setting the Pen property assigns the specified TPen object, rather than replacing the current TPen object.
