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.
You can crop irregular data regions from image files.
To crop an irregular data region:
Open the image in the Image window.
Choose Model | Edit Polygon to open the Edit Polygon window.
Choose a selection tool and 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). |
Click Do It to copy the polygons. Then view the range of Z sections to make sure that all of the data is included in the polygon on each section.

From the softWoRx main menu, choose Edit | Cut Mask.
In the Input field, enter the Image window number. Then click Details to open the Region Details window and enter the Z or T sections to include. Click Close.
In the Cut Mask window, choose which wavelengths to include. In Create Mode, choose one of the following modes and specify whether to act on the inside or the outside of the polygons.
Choosing Data cuts all of the data inside or outside of each polygon and copies it to the output destination.
Choosing Mask creates an output file with only 1's and 0's representing either the inside or the outside of the polygons.
In the Threshold field, set a background intensity to remove from the selection. (For example, setting a threshold of 200 selects only data with an intensity value greater than 200.)
Note With Trim Output selected, the smallest area containing all the polygons is the area written to the output window. With Trim Output deselected, the size of the file has the same x-y dimensions as the original file, but only the part defined by polygons has intensity. |
