Stereo Scan 440 - DCU

Micron Markers
Two types of micron marker can be placed on the image. fIXed and variable. Both
types of maJt.er show a line and a length. the line size will change according to
the magnification of the image. However the variable marker will change scale
according to the magnification. while the fixed one will not.

I
If multiple zones are displayed, the micron marker will display the magnification
of the zone in which its top left corner appears.
Editing a variable micron marker changes the maximum size limit for the line.
Editing a fixed micron marker allows its fixed size to be changed. If a fIXed
micron marker is inserted into a datazone it will be converted to a normal micron
marker using base magnification.

Point to Point
The point to point measurement facility consists of a pair of related pointers and
a ~urement panel and is selected from the Measure~nt ~nu. The points are
labelled Ph and PnR where n is the number of the instance of the point to point
object (it is possible to have multiple point to point objects concurrently).

I
In the measurement panel the distance between the markers is displayed along
with the angle of the line joining the markers. The angle is defined as the angle
between the line PnR and Pn and the line scan direction. measured in a clockwise
direction (see Figure 2.7).
Either point may be moved by selecting and dragging with the mouse. but this
nM::thod of control has two disadvantages:-
