Part of Lesson Plan: Making Selections with Lasso Tools

Activity Overview / Details

Anti-alias-The smoothness of the selection, achieved by softening the color transition between edge and background pixels.

Contrast- Contrast defines the tool’s sensitivity.  This setting can be a value between 1 percent and 100 percent; higher values detect high contrast edges.

Fastening Point- An anchor along your selection. A very small circle appears on the pointer, indicating you have reached a starting point.

Feather-The amount of blur between the selection and the surrounding pixels.  This setting is measured in pixels and can be a value between 0 and 250.

Frequency- The rate at which fastening points are applied.  This setting can be a value between 0 and 100; higher values insert more fastening points.

Width- The interior width, achieved by detecting and edge from the pointer.  This setting is measured in pixels and can have a value from 1 to 40.
