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 semitransparency of the selection,
allowing you produce just the fill you want.
Limiting and Preventing Leakage
In complex drawings, lines don’t always meet. This can create fill leaks into areas you
don’t want to be filled — sometimes through the whole image. You can’t always tell if
there’s a leak just by looking at your image. If you click a small area and see the
prompt, “Now Looking for Extent of Fill,” there’s probably a leak, and Corel Painter is
preparing to fill a bigger area than you had in mind. In this case, you can abort the fill.
You can limit leakage to a specific rectangular area. In typical cartoon line work,
unbounded areas — for example, hair, tail feathers, and brush bristles — sometimes
must be filled. By limiting leakage to a specific area, you can close off these items. You
can also close leaks by copying the lines to a selection (refer to “To copy lines to a
selection” on page 165), saving the selection to a channel, editing the channel, and
then reloading it to the selection. For more information about editing channels, refer
to “Managing and Editing Channels” in the Help.
To abort a fill
• Press Command + . (period) (Mac OS), or Ctrl + . (period) (Windows).
If you don’t catch the fill in time, choose Edit menu > Undo Paint Bucket
Fill, or press Command + Z (Mac OS), or Ctrl + Z (Windows), to undo a fill
that has leaked outside of the boundaries.
To limit leakage
1 Choose the Paint Bucket tool from the toolbox.
2 On the property bar, click the Fill Cell button or the Fill Image button.
3 Drag to create a rectangle that just covers the area you want to fill.
