Transect Drawing Controls
Overview

The transect drawing controls are a version of the Drawing Controls that allows you to view, create, and modify the transect lines that are used in the Transect Views. This option can be found in the Main Display window under the Display->Draw Transect menu item or through the Transects menu in the Transect View.

This display control is a representation of the set of transects that are defined by the transect resource. Not only does it have its own state (that can be saved in a bundle, for example), but it also writes out any transects you may create or change into your local McIDAS-V state directory in a transects.xml file. This transects.xml file (if one is created) is carried over from session to session. Therefore, if you draw transects in one session and save the transects (via the File->Save or Automatically update transects items), the same transects will appear in subsequent sessions when you open the Transect Drawing Control widget.

In this control, there is only one shape that you can draw, a Transect Line. This control also shows a non-editable Transect Shape which displays the full transect line used by any Transect Views, called the "Active Transects". There are also a set of transect lines that are non-editable that are from the system transects property. For an active transect, if the Transect View that it represents has a max distance set then the transect will show this max distance as a rectangular box.

The Transect Drawing Control window consists of three tabs: Controls, Style, and Shapes.

The Controls tab allows for the user to draw features in the Main Display window:

The Style tab controls the appearance of the transect lines in the Main Display window:

These menu options apply to the shapes listed in the Controls tab. Once modifications have been made in this tab, they will be applied to the next transect you draw in the Main Display window, without changing any transects already created. Note that Font and Justification are not valid options for this control, since there is no text component in the Controls tab.

The Shapes tab lists all of the graphical elements:

Double-clicking on an element in the Shapes tab will show its properties editor, which consists of two tabs: Properties and Points.

The Properties tab gives general information about each transect:

You can modify a latitude/longitude value here by double-clicking in one of the cells for latitude or longitude, entering a new value, clicking in another cell, and clicking Apply or OK. The new latitude/longitude values will be applied to the endpoints of your transect line in the Main Display window.
