Painting and drawing with the Art Media tools : Using the Crayon tool
 
Using the Crayon tool
Crayon is a dry media similar to chalk but with a wetter feel that prevents powdering. The tool has infinite pigment loading. As applied by the Crayon tool , its dry pigment tends to penetrate the canvas texture proportional to the pressure with which you apply it. This is due to Corel PaintShop Pro mimicking a solid tool head. The pigment leaves a slightly waxy volume that can smear for a short distance as it is painted over. Crayons do not have a bristle component to the stroke, instead presenting a flat or angled tool surface. The body of the stroke tends to have a fall-off and break up affected strongly by the canvas texture. However, crayon pigment is less transparent than chalk and does not powder.
Crayon is a little more shiny than pastel, smears itself slightly less, but does apply a tiny amount of matter to the canvas and can smooth over bumps if used repeatedly. This is because the volume that is laid down is viscous enough to fill dents but also dense enough to prevent large-range smearing.
Crayon tool options
Edit workspace 
Crayon tool options include
Shape — defines the shape of the crayon tip
Size — defines the size of the tool head in pixels
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
Trace check box — allows the Crayon tool to select the pigment color by sampling the data below the center of the tool regardless of the layer type.
Important! When you hold down the mouse button to begin the stroke, note that a single sample is performed and the resulting color is used for the duration of the stroke.
