<p id="1013168" class="Body">
<a name="1013168"> </a>With the Corel Painter computed brushes, you can brush on gradients, which are gradual transformations of one color into another. Refer to <a href="05-Color11.html#999686">"Using Gradients"</a> for more information. The Corel Painter computed brushes can also brush on patterns (repeating designs). Refer to <a href="04-Textures4.html#1007986">"Using Patterns"</a> for more information.
</p>
<p id="1012644" class="Body">
<a name="1012644"> </a>When you paint with a pattern, you can adjust the pattern's scale. Scale affects a pattern brush stroke in a special way-it determines the resolution of the painted patterns. Small scale causes blurry computed brush strokes. Large scale causes sharper strokes. Here's why:
</p>
<p id="1012646" class="Body">
<a name="1012646"> </a>The brush stroke is always drawn as the entire pattern, sized to fit in the current dab size. Scaling the pattern down very small (say to 20%), makes the brush stroke appear blurry, because the dab is significantly bigger than the pattern. Scale the pattern up to 100% and the dab is as clear as it can get. Settings over 100% have no effect on the appearance of the brush stroke.
</p>
<p id="1012647" class="Body">
<a name="1012647"> </a>Here's how to picture what's going on:
</p>
<p id="1017004" class="Body">
<a name="1017004"> </a>Imagine that the current pattern is 100 pixels across and the current brush size is fifty pixels across. With the pattern set to 100%, Corel Painter shrinks 100 pixels into a 50 pixel area, which is easy for it to do without visible loss of accuracy. If you scale the pattern up to 200%, it looks just as clear as the original, and fitting it into the 50-pixel brush size creates a brush stroke that looks the same as when the pattern was scaled at 100%. Scale the pattern to 50% and the original will be the same size as the brush, so still there is no difference in the resulting brush stroke.
</p>
<p id="1012653" class="Body">
<a name="1012653"> </a>Now, keep scaling downward. As the size of the pattern is scaled below the size of the brush, Corel Painter must increase the size of the pattern to fit the 50 pixel area of the brush stroke. When images are scaled up, after being first scaled down, the image becomes blurry. This is especially noticeable if you scale the pattern well below brush size. At 20%, the pattern now only consists of 20 pixels and has lost eighty percent of the original data. When Corel Painter expands that to 50 pixels (the brush stroke size), the loss of data becomes very visible. Smaller scale settings result in even blurrier brush strokes. Go down to 2%, and the pattern is only 2 pixels across and is able to contain, at most, four colors (two across and two down). When Corel Painter expands that to fit the brush stroke, you won't see any of the original pattern, just a fairly uniform color, across the dab.
