Dab Types
Dab types are media application
methods. Corel Painter produces
“computed” brush strokes using
rendered dab types that are computed
during the stroke.
Earlier versions of Corel Painter used
“dab-based” media application, where
brushes apply small dots of media to
create brush strokes. With Spacing
between dabs set small, strokes appear
smooth. Zoom in close enough, and
you can probably tell that the brush
stroke is made up of tiny dabs of color.
Make a rapid brush stroke or set
spacing between dabs large, and
strokes can become trails of dots.
Rendered dab types create continuous,
smooth-edged strokes. They’re fast
and less artifact prone than dab-based
media application. In fact, you can’t
draw fast enough to leave dabs or dots
of color showing in a stroke, because
they’re just not there. Rendered dab
types allow rich new features, that
were not possible with dab-based
media application.
The Scratchboard Pen illustrates the smooth
stroke that can be accomplished with the Corel
Painter rendered Dab Types.
Corel Painter brushes use one of the
following dab types.
• Circular (dab-based)—Circular
dabs are controlled by the sliders in
the Size and Angle areas of the
Stroke Designer.
• Single Pixel (dab-based)—A
Single Pixel dab consists of one
pixel only. You can’t change its
size. You’ll use single pixel brushes
most often when you zoom in for
editing at the pixel level.
• Static Bristle (dab-based)—Bristle
dabs are controlled by the sliders in
the Size area of the Stroke
Designer. When you select the
Static Bristle dab type, the preview
grid displays a bristly profile.
• Captured (dab-based)—Captured
dabs are dab shapes you create and
capture. Refer to “Capturing
Brush Dabs” on page184.
