• When Preserve Transparency is disabled, erasing or deleting images restores
transparency to the area and reveals the underlying image.
• When Preserve Transparency is enabled, erasing or deleting images reveals the
document’s paper color. In effect, erasing or deleting with Preserve Transparency
enabled is the same as painting or filling with the document’s paper color.
Erasing part of a layer (the top-right wing of the butterfly) with the
Preserve Transparency check box disabled restores transparency (left).
When the option is enabled, erasing reveals the paper color (right).
You can create a layer mask based on the layer’s transparency. A layer mask defines
which areas of a layer are visible in the document window. For more information, see
“Creating Layer Masks” in the Help.
To preserve layer transparency
• On the Layers palette, enable the Preserve Transparency check box.
You can also load a layer’s transparency to a selection. On the Layers palette,
hold down Control and click the layer (Mac OS), or right-click the layer
(Windows), and choose Select Layer Transparency. For more information
about selections, refer to “Selections” in the Help.
Working with Floating Objects
You can make a selection on a layer using the Rectangular Selection, Oval Selection,
Lasso, or Magic Wand tool. Selections on layers function in the same way as selections
on the canvas — you can use them to constrain brush strokes, to isolate an area of the
layer for applying an effect, or to choose an area of the layer to cut or copy. For more
information about working with selections, see “Selections” in the Help.
