5.3. Show All

The Show All command appeared in GIMP 2.10.14. It makes all pixels visible that are outside the canvas and that are normally not part of the image. This allows you to drag new layers and images outside the canvas temporarily to work with them.

5.3.1. Activating the Command

You can access this command from the main menu through ViewShow All.

5.3.2. Basic principles about the Show All Command

When you just open an image, the canvas size is the same as the image size, and applying the Show all command, of course, gives nothing since there is no pixel outside the canvas. So, enlarge the layer using the Scale tool.

Layer enlarged. Command not checked.

Show All

Layer enlarged. Command checked.

When the Show all command is unchecked, pixels spilling off the canvas boundary are not visible.

When the command is checked, all pixels outside the canvas are visible (if the layer size is enough). You can see:

  • The canvas boundary as a red dotted line. You can paint outside the canvas, in the limit of the layer. Changes made outside the canvas are not exported with the image, unless you enlarge the canvas size using Canvas Size.

  • The layer boundary as a yellow dotted line.

  • A large checkerboard area indicating there is no pixel.

    The checkerboard area is infinite: whatever the image window size, it persists.

5.3.3. Using the Show All command

We will clone from a new image onto the image.

  • Open your image, check Show All, and enlarge layer.

  • Open the new image. A new layer is created for this new image. Click and drag this new layer onto your image. Use Move tool to put the new image outside canvas.

  • Make new layer active. Use Clone tool and Ctrl-click on the new image to make it the source.

  • Make image layer active. Paint on your image to clone the source. You see that pixels in checkerboard area are cloned.
