Canvas size

The Canvas Size command in the Image menu allows you to alter the dimensions of an image. However, unlike the Image Size command, this is done without changing the resolution. In effect, when the width or height is reduced the image is cropped, and when it is increased transparent pixels are added to fill up the extra space. (Note that the image canvas is usually surrounded by a gray area if the canvas is smaller than the image window. This gray area is inaccessible to the Photopaint tools. Increasing the canvas size creates a newly accessible area, hence allowing you to add a caption, say, to the bottom of a scanned photograph.)

  1. In the "Canvas Size" dialog you can make changes in the Width and Height boxes. Note that the amount of space required for the image is shown just above.

  2. In the Anchor box there is a grid of nine squares which helps you to choose where the image will be located on a resized canvas. Since changing the canvas size results in either a cropping or expansion of the canvas, there are two basic uses of the anchor grid:

Once you are satisfied with the width, height and anchor grid setting click on OK to implement the changes.
