SELECTING
A selection is a specific area of the image that can be edited or to which an effect can be applied. A selection can be the whole image or part of an image.
Definitions: | |
Marquee | Rotating dotted lines that outline the selected area. |
Feathering | Softens the edges of a selected area and causes the image to fade into the background. |
Floating Selection | A selection that resides just above the image. Floating a selection enables you to select without affecting the original image. The Layers palette indicates a floating selection with the label "Floating Selection." |
Standard Selection | A selection of part of the image. Moving or modifying a standard selection modifies the image. Paint Shop Pro provides options that enable you to float and defloat a selection. |
Antialias | Selected edges can appear jagged. Antialiasing smoothes the edges. |
Matting | When you move a selection, some of the pixels around the edges are also moved. Matting removes these pixels. |
Defringe | Causes nonfeathered pixels to bleed outward, creating a smooth transition from the selected area to the surrounding area. |
Alpha Channel | Used to save selections with the image. Selections can also be saved to disk. |
Sample Merged | When Sample Merged is selected, the Selection tool selects from all layers of the image. When Sample Merged is not selected, only the active layer is affected. |
Match Mode | Method used to select an area by using the Magic Wand. The choices are RGB value, Hue, Brightness, or Pixels. |
Tolerance | Specifies how close a match must be (the type of match is specified in the Match Mode field). A tolerance of zero requires an exact match. A tolerance of 200 provides the maximum amount of leeway in determining whether there is a match. |
Brightness | The amount of white contained in a pixel. |
Paint Shop Pro provides three tools for making a selection: the Selection tool, the Freehand tool, and the Magic Wand.

The Freehand Tool
The Freehand tool provides three selection methods: the freehand method, the point-to-point method, and the Smart Edge method. With the freehand method, you use the pointer to draw the area you want to select. With the point-to-point method, you create a selected area consisting of straight lines. The Smart Edge method is used to create a selection along a border of contrasting color or light.
