Arrange mosaic images

The relative order of the images that compose a mosaic can be modified in order to control the way they overlap. There are four operations available to arrange mosaic images. 

To apply any of these operations, make sure the mosaic tool is active and select the image whose position is to be modified by clicking on it. Select more images by clicking on each of them while pressing Shift. The selected images are shown with a surrounding red box as depicted in Figure 1. To apply the desired operation, select it from the Mosaic main menu, or from the context menu that appears when right clicking on a selected image. Figure 1 shows the effect of bringing an image to front.
