The Visual Spatial Editor provides the following useful features, some of which have not been mentioned until now:
-
With the
Image Cut Levels
button (second right button above the display window) the intensity scaling of the displayed image can be changed.
-
Changes made in the pointing table will also cause an update of the pointing markers in the image display.
-
Vice versa, pointing changes made in the image display (e.g. dragging one or more pointing positions) will also update the pointing table.
-
When a row is selected in the pointing pattern table, the corresponding FOV marker in the image display is selected.
-
The coordinates for the pointing pattern can be in either absolute or relative (to the source) coordinates.
-
If offset coordinates have been selected, a change of the source coordinates field causes all the FOVs on the image to move. When absolute coordinates are selected, the positions of the FOVs do not change even though the source coordinates change.
-
The
FieldSourceEditor
panel informs the user how many Targets are using the FieldSource. When the FieldSource is used by more than one target a warning icon will be displayed. Editing the FieldSpec parameters will affect all Targets that have this FieldSource attached. When a Target is selected and the FieldSource is used by more than one target, the
Edit Only This
button appears along with the information. To only edit the FieldSource parameters for the target which is displayed, click this. This duplicates the parameter set and attaches the FieldSource only to the target which is edited.
-
With the middle cursor button, distances in the image display can be measured.
