You can constrain the fill to a
rectangular area by dragging with the
Paint Bucket tool.
To choose a lock-out color:
1 On the Colors palette, choose the
color you want protected.
2 Double-click the Paint Bucket tool
in the toolbox.
3 In the Lock Out Color dialog box,
click Set.
The color swatch updates to the
new color, and the Lock Out Color
check box is enabled.
Filling Cells
You can use the Paint Bucket tool to
fill the interior of areas bounded by
lines. This is especially good for
producing solid fills of regions
bounded by anti-aliased lines.
If you want to fill regions completely,
without affecting the lines, you can
first copy the lines to a selection.
Then, when you fill the cells, the lines
are protected. For information about
the method used to copy lines to a
selection, refer to “Creating an Auto
Selection” on page 208. You can also
control how well the Paint Bucket
respects the selection by setting the
mask threshold.
Cartoon animators used to paint lines first and
then fill them by painting on the back of the
cell.
To copy lines to a selection:
1 Choose Select menu > Auto
Select.
2 In the Auto Select dialog box,
choose Image Luminance from the
Using pop-up menu.
3 Click OK.
Corel Painter creates a selection
that will protect the dark lines.
When you protect anti-aliased or
non-black lines in this way, the
lines in the selection have varying
levels of transparency—depending
on the pixel luminance. The Mask
Threshold lets you compensate for
the semi-transparency of the
selection to get just the fill you
want.
To set the mask threshold for the
Paint Bucket:
1 Double-click the Paint Bucket tool
in the toolbox.
2 In the Lock Out Color dialog box,
move the Mask Threshold slider.
This slider controls how well the
Paint Bucket respects the selection.
At zero, the fill will overrun the
selection boundaries. Higher
threshold values force the fill to
respect the boundaries. The
appropriate threshold setting
depends on the softness of your
lines. You’ll have to experiment
with the Mask Threshold slider
settings until the fill is limited to
the area within the line.
