Resizing Images and the Canvas in Painter 12

Resizing Images and the Canvas in Painter 12

You can change the physical dimensions of an image by resizing the canvas and the image together, or by resizing the canvas area only. It is important to understand the distinction between the two resizing techniques.

When you resize the canvas and image together, the image dimensions and resolution change, but the image appearance does not. For example, if you resize an image at 300 ppi to 150 ppi, the image size may be smaller, but it looks the same.

The image was resized by modifying the resolution.

Alternatively, when you resize only the canvas area, both the image dimensions and appearance change. For example, if you increase the size of the canvas, a border appears around the image. If you decrease the size of the canvas, the edge of the canvas is trimmed. In addition, the image resolution is affected.

The canvas area is resized in order to apply an empty border around the edge of an image.

It is also important to note that the size of the onscreen image is affected by the pixel height and width, the zoom level, and the monitor settings. As a result, the image will be displayed as a different size onscreen than when it is printed.

To resize the canvas and image content together

1. Select Canvas Resize.
To avoid distortion by maintaining the width-to-height ratio of the image, enable the Constrain File Size check box.

2. In the New Size area, type values in the Widthand Heightboxes.

If you enable theConstrain File Size check box, you need to type values only in the size box; the other values are adjusted automatically.
If you choose pixelsor percentas the unit and enter a value, the Constrain File Size check box is automatically disabled. Increasing the image dimensions significantly may cause the image to appear stretched and pixilated.

To resize the canvas area

1. Choose CanvasCanvas Size. 2 In the Canvas Size dialog box, specify the number of pixels you want to add to any side of the canvas.


To reduce or trim the canvas size, specify entries as negative values.
