Image Processing Reference
Here is the procedure to create a single-color image frame:
• Open the girl-color.png image, which is in the SampleImages folder on
• Access the Image > Canvas Size menu item to increase the width or height
of the canvas to the desired size. Press Enter . The chain icon should be
closed (default) so that the sides of the canvas will adjust proportionately.
Click the Center button and then click Resize to enlarge the canvas.
• You can optionally add an alpha channel (right-click menu in the Layers
dialog) to the background layer of your image. Add a new layer underneath
the existing one and colorize it; white or any other color will do.
