Scale a canvas plane

Scaling resizes the canvas (including the content of its image layers) by changing its width, height, or resolution (pixels per in/cm). The new width and height can either be specified in pixels or in real world units (in/cm).

Scaling is always done with respect to the center point.

If you only want to change your view of a canvas plane, do not move, resize or scale it.

See Change your view of a canvas plane.

You can also move or scale an individual image layer.

See Move, scale, or rotate an image layer.

To scale a canvas plane

In the Construction Plane Editor (Windows > Editors > Construction Plane Editor) or from the lister on the window’s title bar, click on the canvas you want to scale.
Choose Canvas > Resize Canvas to open the control window.
Set Resize Mode to Scale.
If you do not want to maintain the aspect ratio (width to height ratio), turn off Lock Aspect Ratio.
Change any of the following values:
- Width and/or Height in pixels
- Width and/or Height in real-size units (in or cm)
- Pixels per in/cm (resolution)
A black outline shows where the edges of the resized canvas will be.
Press the Accept button.
A confirm box appears warning that resizing cannot be undone.
Click OK in the confirm box.
The canvas is scaled with respect to its center point. The content of the image layers is also scaled to fit the new canvas size.
