300 Corel PaintShop Pro X7 User Guide
• Traditional — selects pixels that match red, green, and blue
values, with a bias toward lightness variations. This match mode
is therefore more discriminating than the RGB Value match
mode.
• All Opaque — selects all pixels that are not completely invisible
(that is, having an opacity value of 1 or greater). Choosing this
option disables the Tolerance control.
• Opacity — selects pixels that match the opacity value of the
pixel you click.
3 Check the settings of the following controls on the Tool Options
palette, and modify them if necessary:
• Tolerance — controls how closely the selected pixels match the
pixel you click in the image. At low settings, only similar pixels
are chosen; at high settings, a wider range of pixels is selected.
• Feather — softens the edges of a selection by specifying a fade
width (0 to 200 pixels)
• Use all layers — searches for matching pixels across all layers in
the image
• Contiguous — selects only pixels that connect to the pixel you
click
• Anti-alias — produces a smooth-edged selection by partially
filling in pixels along the edge, making them semitransparent.
You can use this option inside or outside the selection marquee.
4 Click the image area that contains the pixels you want to match.
The selection marquee surrounds all matching pixels.
You can change the number of pixels you select by undoing the
selection, adjusting the Tolerance setting, and making a new
selection.
