Canvas > Resize Canvas

Crops, expands, scale, or moves a canvas plane.

To resize a canvas plane by cropping or expanding it, choose Canvas > Resize Canvas.

Black manipulators appear on the edges of the canvas. Crop or expand the canvas by moving any of the manipulators on the edges or corners of the canvas. Blue crosshairs indicate the horizontal and vertical center lines.

To move the position of the resized canvas, drag the center cross. As you move the outline of the canvas around, it will subtly snap to the center line when you get close to it, and the blue line will appear when you are on top of that horizontal or vertical center line.

To provide numeric input,or to scale the plane, choose Canvas > Resize Canvas ❒ to access the control window.

Resize Canvas Control Options

Resize Mode: Scale – Resize the canvas (including the content of its images layers) by changing its width or height). Scaling is always done with respect to the center point.

Crop/Expand – Resize the canvas by “cutting” or “adding” material around its edges, relative to an anchor point. The resolution (pixels per in/cm) does not change. The content of the image layers does not change size but gets cropped along with the canvas. This is the default behavior.

Image Pixels

Width: Width of the canvas in pixels
Height: Height of the canvas in pixels

Image Size

This section displays only when Resize Mode is set to Crop/Expand.

Unit: Choose either Inches or Millimeters as the world size units for the two measurements below.
Width: True width of the canvas in the units given by Unit.
Height: True height of the canvas in the units given by Unit.
Pixels per in/cm: Resolution of the canvas (given by length in pixels divided by true length). Changing the resolution modifies the true image size Width and Height accordingly. The Width and Height in pixels are not affected.

This option only appears when Resize Mode is set to Scale.

Aspect Ratio

Lock Aspect Ratio: If this option is checked (default), the aspect ratio (width to height ratio) of the canvas is maintained when either the width or height of the canvas is modified.

Anchor

This section displays only when Resize Mode is set to Crop/Expand.

Vertical: Choose Top, Center, or Bottom to specify what part of the canvas remains fixed as it is cropped or expanded in the vertical direction.

This option only appears when Resize is set to Crop/Expand.
