Vector PrortJe
Procedures
Selecting the vector profile ~urement facility brings up the profile
display and creates a ~urement line (with the identifier 'Prof). This
line may be moved on the stored image and each end positioned
individually.
When the line is dropped the trace on the profile display describes the
grey levels lying under the line. Note that the lefnnost point of the line is
the leftmost position on the proflle display.
The profile display has a pair of cursors which may be IOOved
horizontally. The grey level at each cursor position is displayed on the
profile display.
Associated with the measurement line is an annotation panel loaded
from file PROF.ANN containing the profile width ~urement
parameter which is the distance (along the measurement line) reflected
by the cursor spacing.
As with other ~ment objects if the profile line crosses into
another zone the measurement is invalidated and displayed as zero. A
warning BEEP is given.
The nonl1al operational procedures for measurement objects apply to these
~ure~nt objects:-
In Move mode the individual objects may be DX>ved about the image
In Edit mode selecting the object causes the 'handles' for the object to
be displayed. these may be dragged or moved using the 'precision'
technique described in the On-line Help. The object may be deselected
either by selecting escape on the popup menu or. if the popup menu is
displayed. by clicking the right mouse button over the image.
