134 Painting and Drawing
Check Contiguous to erase only within-tolerance pixels connected to
each other; when unchecked, all in-range pixels are erased.
Check Use All Layers to take color boundaries on other layers into
account, although erasure happens only on the current layer.
Antialias smooths the boundary between the erased area and the
remaining area.
Erasing using pen tablets
During retouching, areas of your image can be erased by brushing out, either by
using your mouse or, if available, a pen tablet. For tablet users, PhotoPlus
supports pressure sensitivity, with tablet calibration and key assignment possible
directly from within the program (via Pressure Studio).
Using patterns
The Pattern Tool lets you paint a pattern directly onto your canvas. In
effect, it "clones" any pattern bitmap you’ve selected while providing the
flexibility to paint wherever you wish, and control opacity, blend mode, and so
on. Like the Clone Tool, the Pattern brush picks up pixels from a source—in this
case, the bitmap pattern—and deposits them where you’re drawing. You can
choose a pre-defined, tiled bitmap pattern from the Patterns dialog, or define
your own patterns.
As an example, patterns can be used effectively as a painted background, perhaps
when creating web graphics.
