The Align tool is useful to align the image layers with various image objects. When this tool is selected, the mouse pointer turns to a small hand. By clicking on an element of a layer in the image, you choose the layer which will be moved (with Shift + click, you can choose several layers to be aligned); this focalised layer has small squares in corners. Various buttons in the dialog allow you to select how the layer will be moved. And you can select the image object (other layer, selection, path...) the selected layer will be aligned on. This object is called target.

Overview

The available tool options can be accessed by (double)-clicking the align Tool icon.

Align
Relative to:

This is the target - the image object the selected layer will be aligned on.

  • First item: the first selected item when selecting multiple layers holding the Shift key. Note that there is no “first item” when you select multiple layers using rubber-banding.

  • Image: the image is used as a target.

  • Selection: the minimal rectangular region covering the active selection.

  • Selection: the minimal rectangular region covering the active selection.

  • Active Channel:

  • Active Path: This option is not yet handled.

These buttons become active when a layer is selected. When you click on one of these buttons, you align the selected layer with left edge, horizontal middle, right edge, top edge, vertical middle, or bottom of the target.

Distribute

These options seem to differ from the “Related to ” options only by the possibility to set an offset. This offset is the distance which will separate the selected layer(s) from the target once the alignment is performed. It can be positive or negative and is expressed in pixel. Distribute add this offset to the left edges, horizontal centers, right edges, top edges, vertical centers, or bottoms of targets.

Offset

This entry controls the amount of displacement that could be given to the desired alignment effect (in pixel) regarding the target. The default value is 0; it can be positive or negative.
