Many surface control effects let you use paper as the control medium.

<a name="1015742"> </a>Filling Images Based on Color
</h3>
<p id="1015814" class="Body">
<a name="1015814"> </a>You can use the Paint Bucket tool to fill image areas based on pixel color. This method can be used on the canvas or in a channel. Corel Painter fills areas based on color boundaries and the current Tolerance and Feather settings.
</p>
<p id="1015827" class="Body">
<a name="1015827"> </a>Tolerance sets the amount of variance allowed from the color of the pixel you click on. With Tolerance set low, the Paint Bucket fills only contiguous pixels that are very close to the color of the pixel you click on. With Tolerance high, the Paint Bucket fills a greater range of colors.
</p>
<p id="1015832" class="Body">
<a name="1015832"> </a>Feathering softens the edges of the fill by controlling the fill opacity for pixels with colors outside the Tolerance range. With Feather set to zero (the default), only pixels in the Tolerance range are filled. With Feather set low, pixels with colors just outside the Tolerance range receive partial fill. Increasing the Feather setting increases the range of colors that receive partial fill. Pixels with colors further from the Tolerance range receive a more transparent fill. Typically, when Feather is high, Tolerance is set low.
</p>
<p id="1015929" class="Body">
<a name="1015929"> </a>The Lock Out Color feature protects areas of a given color from accidental filling. You can choose a color that will not accept filling when clicked with the Paint Bucket. Black is the default locked-out color.

</h3>
<p id="1015786" class="Body">
<a name="1015786"> </a>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.

<p id="1016683" class="Body">
<a name="1016683"> </a>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 <a href="12-Selections4.html#1014518">"Creating an Auto Selection"</a>. You can also control how well the Paint Bucket respects the selection by setting the mask threshold.

<p id="1014577" class="ToDoBody">
<a name="1014577"> </a>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.

<p id="1016052" class="ToDoBody">
<a name="1016052"> </a>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.

<p id="1016168" class="Body">
<a name="1016168"> </a>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.
</p>
<p id="1016169" class="Body">
<a name="1016169"> </a>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.
</p>
<p id="1017303" class="Body">
<a name="1017303"> </a>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.
</p>
<p id="1017373" class="Body">
<a name="1017373"> </a>You can also close leaks by copying the lines to a selection (refer to <a href="06-Painting14.html#1016648">"To copy lines to a selection:"</a>), saving the selection to a channel, editing the channel, and then reloading it to the selection.
