: How to show boundary of every layer in Gimp? Using Gimp, I am working on a sprite image made of lots of icons, each on a separate layer. I would like to check that there is no overlap

@Murray976

From Gimp documentation:


5.10. Show Layer Boundary

The Show Layer Boundary command enables and disables displaying the
yellow dotted line that surrounds a layer in the image window. The
dotted line is actually only visible when the layer is smaller than
the image window. When the layer is the same size as the image window,
the layer boundary is obscured by the image border.

You can set the default for the layer boundary in the Image Window
Appearance dialog.

5.10.1. Activating the Command

You can access this command from the image menubar


through View → Show Layer Boundary.

There's not a way to directly do what you ask, to my knowledge. There is a way to "link" layers (click next to eye in layers dialog), but this linkage seems to cause only movement (dragging) to operate on the group of layers; all other operations continue to work on a single layer.

If what you want is to see if the rectangular boundaries of each layer overlap any other layer's boundaries, you may be able to do so with some preparatory work. You add a "layer mask" to each layer concerned, probably all white (meaning opaque). You turn off visibility of any background layer so that the gray check pattern of transparency will show. You can then show for each layer the white rectangle where the layer exists by alt-clicking the mask icon in the layer dialog (which appears next to the image icon when the mask is created). Do this for all the layers concerned and see if the rectangles overlap. (alt-click again to go back to normal layer image display.) Basic mask operations are covered in Gimp docs 7.21 - 7.26.
