The Line Tool
Use the Line Tool to add straight lines to your images. This tool also measures the distance of the line you draw. Line annotations can be helpful for outlining areas, highlighting roads, pointing at objects, designating paths or routes, or pointing to an object to which a text note might apply. You can add straight lines or lines with corners and multiple parts.
Note: Before creating the annotation, you can change default properties with the Line color and Line weight toolbar buttons. (You can also change these properties by clicking Preferences->Defaults tab.)
To annotate an image with a line:
1 Click the Line Tool. The application switches to drawing mode. (The cursor changes to a crosshair.)
2 Click the location in the image at which to start the line. The point you clicked is marked.
3 For multi-segment lines, click the next point. A line connects the segment between the last two points. Repeat this step until all line segments (except the last one) are drawn.
4 Double-click the last point to end drawing mode.
The annotation is listed as "Line" in the default annotations folder in the Workspace panel along with a small square showing the line color. The line distance is shown in the Status Bar. The annotation properties come from application settings ("Preferences" button, "Defaults" tab). You can change an annotation's properties (color, opacity, weight, and description in the Workspace panel) at any time by using the Properties panel.
