Canvas Size
The Canvas Size command allows you to increase or decrease an image’s canvas size. Increasing the canvas size adds space around an existing image. Decreasing an image’s canvas size crops into the image.
1. Do one of the following:
 Choose Image > Canvas Size
 Click the Canvas Size button on the toolbar
2. Use the following options:
Width
The horizontal dimension.
Height
The vertical dimension.
Units
Choose the units of measurement. You can select between Pixel, %, Inch and Centimeter.
Keep aspect ratio
Use this option if you want the image width / height aspect ratio to be fixed during resizing. If this option is checked, then typing a new Width value will maintain a proportional Height value, and vice versa.
Color
Select a fill color for horizontal or vertical dimensions larger than the image dimensions.
Transparent
This option allows you to choose a transparent background.
Anchor
This option allows you to specify which sides of the canvas to add to or delete from. By default, the center anchor is selected, indicating that changes to the size of the canvas are made on all sides.
