AngleParams Table
The AngleParams table contains properties
used by the
CMeasureAngles class. This table is used to
change properties using the class
SetParams method.
The reference table below lists the angle
measurement properties and their update status. For each property
in the top half of the table, there exists a corresponding update
status flag in the lower half of the table. The name of the update
status flag prefixes the property name with the word Set. For example, the property bCentroid has the update status flag bSetCentroid. Normally, the update status flag is
set to false. But to change it using
the AngleParams table, you must the the status flag to
true. Create an AngleParams
table containing only the properties you wish to change. Then call
the class
SetParams method with the AngleParams
table as its parameter.

the object has positive (true) or negative (false) values relative
to the background.

Specifies whether the centroid is computed for
transferring angle markers from one image to the next.
|
|
bUseDockingPane
|
false
|
Specifies whether to list angle measurements (the
included angle, etc.) in a docking pane (true) instead of a
measurement window (false).

Example
Suppose an image window exists on the Mira screen
and you have a collection of approximate coordinates of objects for
which you wish to compute the distances and angles between them.
You wish to improve the approximate coordinates by computing the
center at each vertex and at each endpoint. The script below
enables centroid computation at both the vertex and each endpoint,
and sets the drawing color and line thickness before drawing the
angles on the image.
