Does anyone know how to set the threshold for the theoretical bounding box in Photoshop 6? What I mean by this is that when pixels on a layer fall below a certain opacity, they're not recognised as as part of that layer by the bounding box that is used when transforming etc. This also affects selections - when you control/command click to select the pixels of a layer, any pixel below the opacity threshold will not be included within the visible marquee that indicates the selection (though it will actually be selected - you can see this by going into quick-mask mode). Is it possible to re-define that transparency threshold so that faint tints etc can be transformed without having to insert a bit of opaque paint somewhere on the layer? Cheers, Paul.
