TCanvas.Width property
The
Width of the Canvas.
Declaration
property Width: Integer read GetWidth;Description
Width is a read-only
Integer property which contains
the horizontal dimension in
Pixels for the canvas drawing area.
Height and
Width determine the limits for the
2-dimensional coordinate system used to access the Pixels on the drawing
surface.
The value for the property is determined by calling the
GetDeviceSize routine using the Handle for the class
instance. The property value is 0 (zero) when Handle has not
been assigned (contains 0).
Use Height to get the vertical dimension for the drawing surface.
Changing the value for Height or Width in TCanvas is not allowed. These
values are controlled using the capabilities in an image format or output
device, and are normally handled in classes which implement the canvas.
