92 Manipulating Images
The Modify item on the Select menu (or right-click on selection) provides a
submenu with the above options, along with other intelligent selection options:
• Grow and Similar both expand the selection by seeking out pixels
close (in colour terms) to those in the current selection. Grow only
adds pixels adjacent to the current selection, while Similar extends the
selection to any similar pixels in the active layer.
Both options use the tolerance setting entered for the Magic Wand
Tool on the context toolbar. As the tolerance increases, a larger region
is selected. Typically when using these tools, you'll start by selecting a
very small region (the particular colour you want to "find" in the rest
of the image).
• Choose Border to create a new selection as a "frame" of a specified
pixel width around the current selection.
• The Invert option selects the portion of the active layer outside the
current selection. Unselected pixels become selected, and vice versa.
