Unlike the Palette Knife, the purpose of the Smear tool is to smear existing pigment, including pigment that has no volume on the canvas, such as pencil. This simulates using a cloth or finger to softening out chalk or pencil strokes on a real-life canvas.
The Smear tool only interacts with pigment already on the canvas, and has no loading of its own. When used on dry pigment, it will have a smudge effect. When used on wet pigment, it will have a smear effect.
This tool's functionality differs from real-life smearing in that its operation changes based on the pigment type you're trying to smear. But it does mimic the various real-life methods used to distort color masses such as fingers on pencil, rags on oil, etc.
Smear tool options include:
Shape: Choices include Round or Square.
Size: Defines the size of the tool head in pixels. Note that you can also adjust the Size setting via the keyboard.
Thickness: Defines the aspect ratio of the tool head.
Rotation: Defines the angle of head rotation in degrees
Head Tracking: Controls whether the tool head bends around the path of the user’s stroke, or remains at a fixed angle.
Like other Paint Shop Pro tools, the Smear tool comes with presets. To use a preset:
In the Tool Options palette, click the Presets button. This displays a list of preset styles.
From the list, choose the desired tool preset.
