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 centroid radius when the vertex is adjusted to the centroid coordinates. |
nTrackingSearchRadius |
15 |
Specifies the tracking radius when transferring angle marker coordinates to the next image in the image set. |
bCentroid |
false |
Specifies whether the vertex coordinate is updated to centroid coordinates before drawing on the image. |

false |
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). |

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.
|
-- attach an image window |
|
-- leave script if no image window |
|
|
|
-- get the top-most or only image |
|
-- leave script if no image |
|
|
|
-- create a CMeasureAngles object |
|
-- setup an AngleParams table |
|
-- use a comma after each "name=value" pair |
|
-- enable centroid for vertex |
|
|
|
-- enable centroid for endpoints |
|
|
|
-- enable new marker color |
|
|
|
-- enable new line thickness |
|
|
|
|
|
-- set the new properties |
|
|
|
-- vertex coordinates |
|
-- first endpoint coordinates |
|
-- second endpoint coordinates |
|
-- Add an angle marker to the image |
