Resolution Digital images consist of a grid of square pixels. Each image has a size measured in two dimensions, such as 900 pixels wide by 600 pixels high. But pixels don’t have a set size in physical correctly in every GIMP installation. 3.2 Main Windows The GIMP user interface is now available in two modes: • multi-window mode, • single window mode. When you open GIMP for the first time, it opens above shows the most basic arrangement of GIMP windows that can be used effec- tively. You can notice two panels, left and right, and an image window in middle. A second image is partially masked. The left

like this: Figure 5 From the menu shown in Figure 5, you can probe further down into more choices. For example, to make sure the image is full-color, you should move the mouse to select "Filters pixels from Image D where Image B is white. The composite window will have pull- down menus for your choices. Look at the titlebars to find which actual images correspond to Images A, B, and D.
