How can I select the convex hull of an existing selection in Photoshop. In other words, how does one fill the holes in a selection in Photoshop?
Consider a donut shape. You use the wand to create a selection of the donut shape, but the hole of the donut remains unselected. Is there a tool or sequence of actions to fill the "donut holes" in a selection, preserving the precision of the outermost selection lines?
This same question was asked previously, but for Gimp.
