Use the Edit Polygon tool to select irregular data regions. This tool is applied differently than the tools for selecting rectangular regions. While selecting rectangular regions is usually used within other tools, the Polygon Editor stands alone. You must use the Polygon Editor tool with Cut Mask if you want to then apply another tool only to the selected region.
To select an irregular data region:
Open the image in the Image window.
Choose Model | Edit Polygon to open the Edit Polygon menu.
Choose a selection tool (e.g.,
)
from the Edit Polygon menu. Then press and hold the left mouse button
to draw a polygon around the area of interest.
To copy this region across wavelengths, time points, or through Z sections, choose Edit | Propagate Polygons from the Edit Polygon menu and enter the appropriate ranges.
Tip You can also select time points. You can select ranges or you can enter selected points (e.g., 1, 3-5, 20-25). |
5. Click Do It to copy the polygons. Then view the range of Z sections or time points to make sure that all of the data is included in the polygon on each section.
Tip You can change selected
points on a polygon using the |
button. You can move a selected polygon by selecting it
with the 
tool
and dragging it to a new location.
