Limiting and Preventing Leakage

In complex drawings, lines don’t always meet, which can cause the fill to leak into areas that you don’t want 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, 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.

To undo a fill

•

To undo a fill, do one of the following:

•

Choose Edit

Undo Paint Bucket Fill.

•

Press Command + Z (Mac OS), or Ctrl + Z (Windows).

To limit leakage

Choose the Paint Bucket tool

from the toolbox.

On the property bar, click the Fill Cell button

or the Fill Image button

Drag to create a rectangle that just covers the area you want to fill.

If there is no leak, only the area within the lines is filled. If there is a leak, the fill goes outside the area, but not beyond the constraints of your rectangle.

To close a leak

Copy the lines to a selection.

Choose Select

Save Selection.

In the Save Selection dialog box, choose New from the Save To pop-up menu.

Click OK.

A new channel is displayed in the Channels panel.

In the Channels panel, display and select the channel.

Click the Brush Selector on the Brush Selector bar.

In the Brush Library panel, choose the same brush you used to create the lines.

In the Color panel, set Black as the current main color.

Paint in the channel to close the gaps.

Choose Select

Load Selection.

In the Load Selection dialog box, choose the modified channel from the Load From pop-up menu.

Enable the Replace Selection option to replace the original with the edited version.

If you want to adjust the mask threshold, double-click the Paint Bucket tool

in the toolbox, and move the slider.

The channel does not have to be selected to contain the fill. If you deselect the channel in the Channels panel, the loaded selection is still in effect.

Edit the channel to close leaks. Remember to load the channel back into the selection after editing.
