FOXIT READER 5.1
The Measure Tools enable you to measure distances and areas of objects in PDF
documents. The measure tools are especially useful when you need to know the
distances or areas associated with objects in a form or computer-aided design
(CAD) drawing or when you want to measure certain areas of a document
before sending to a professional printer. The measure tools are available to
Reader users only if the PDF creator enables measuring functionality.
When you use a measure tool, the tool dialog box displays the measurements of
the line segments you draw.
Measuring the objects
Choose Comments > Measure Tools > [measure tool name], or click the
measure tools on toolbar, and do any of the following:
Select the Distance Tool
to measure the distance between two points.
Click the first point, move the pointer to the second point, and click again.
The measurements will appear on the page.
Select the Perimeter Tool
to measure a set of distance between
multiple points. Click the first point to start, and then click each point you
want to measure. Double-click the last point to end measuring.
Select the Area Tool
to measure the area within the line segments that
you draw. Click the first point to start, and then click each point you want to
measure. After you have clicked at least two points, click the first point or
double-click the last point to complete the area measurement.
Note: You can also choose to complete or cancel measurement by right-clicking
and choosing options from the context menu.
After selecting the measuring tool, do any of the following in the pop up dialog
To change the scaling ratio (such as 1:2) on the drawing areas, specify the
appropriate numbers in the tool dialog box. If necessary, change the unit of
measurement next to this ratio.
Check Measurement Markup in the tool dialog box if you want the lines you
draw to appear as a comment. You can put the pointer over the
measurement with the Hand tool selected so that you can view the
measurement and annotation you have drawn.
