on the options bar. Click once on a white pixel on the canvas. Most of
the white pixels are removed up to the point where white pixels mix
with the edges of the brushstroke (see Figure 8.4). The checkerboard
pattern represents transparency (areas where there are no pixels).
You can adjust the
size and opacity of
the checkerboard
pattern in the appli-
cation preferences
under transparency

7. Press Cmd+Z to undo the Magic Eraser. Toggle off the Brushstroke
layer by clicking its eye icon in the Layers panel. Select Shape 1 in
the Layers panel. Choose Layer a New a Background From Layer.
The transparency surrounding the blue rectangle is replaced by white
pixels; the layer is locked and renamed Background.
8. Toggle on the Brushstroke layer and select the layer by clicking the
word Brushstroke . The white pixels on the Brushstroke layer again
obscure the new Background layer.
You can toggle a
layer's visibility
without selecting the
layer.
9. Open the blend mode drop-down in the Layers panel and select
Multiply (see Figure 8.5). You can now see both the brushstroke and
the rectangle through the white pixels on the Brushstroke layer.
You'll learn more about blend modes later in this chapter.
