Using Paint Shop Pro, if you zoom in far enough on an image, you can see the squares. The colors available to you while you are working with Paint Shop Pro are the active colors . The width and height can be set in pixels, inches, or centimeters. The dimensions you set determine the physical size of the image. You can later change the image size by using the Resize dialog box.
Resolution refers to the number of pixels per inch or the number of pixels per centimeter.
As an example, if you have a 300-600 dots per inch printer, create your image at 75 to 150 pixels per inch. In addition to specifying the width, height, and resolution, you must also specify image characteristics such as background color and image type. Your selection in the Background Color field will become the color of the canvas on which you will create your image. Your field choices are foreground or background color, white, black, red, green, blue, or transparent. You determine the foreground and background colors.
