THE LINE ROI GUI

1. Cursor Information

The positional coordinates of the cursor is displayed in the information bar at the bottom of the GUI. Also, the minimum and maximum values are displayed.

2. Other functions

• The "Stats..." button is used to calculate a statistical analysis of the ROI image. The results will be displayed in the STATISTICS GUI.
• The ROI profile may be exported and printed using the "Print..." button. A PRINT DIALOG GUI is invoked, and options include saving the file (by default a postscript file is created, printed and then deleted).

3. An Example

This example shows a horizontal line profile (the image is of a chest of plastic draws) and the corresponding LINE ROI GUI. The line profile displayed in this GUI is (like most of DIVA's line plotting GUIs) capable of zooming - see below.

4. Zooming Option

Click, drag and release to zoom into the line profile. This technique can be repeated (the minimum x-range is 5 pixels). Click and release to return to the original range.

The minimum and maximum values are updated to the zoomed
