Count Tool
The Count tool places a markup for each mouse click, associating a running total of counts with each markup as it is placed. It is somewhat similar to Sequences in the Tool Chest, except that it places a pre-configured (and usually less obtrusive) symbol on the PDF and keeps a running tally, per page, of each item counted, whereas Sequences count on the PDF, do not keep a running tally, and treat each markup placed separately rather than grouping them in the Markups list.
Counting Objects in a PDF
-
Count or press SHIFT+ALT+C. - Select the Properties panel and set the Count measurement's appearance, if desired.
- This and other properties are also available on the Properties toolbar when a Count markup is selected.
- If you are going to place Count measurements across multiple pages and will need to be able to get a total across all pages, change the Subject on the Properties panel to something unique and easily identifiable. This is because Count measurements are automatically split up by page when they are placed; using an identifiable Subject will make it easier to get a total across those pages by sorting the Markups list by Subject.
- Click each object in the PDF to be counted.
- Press ESC after placing the last Count markup to stop counting.
Viewing a Running Total
In multi-page PDFs, Count measurement groups are automatically split up by page. You can easily view the running total of any Count measurement by selecting it on the PDF. The corresponding entry in the Markups list will be highlighted automatically and the count total can be seen in the Count column.
Tip: To be able to get a count total across multiple groupings, give each group the same, easily identifiable Subject on the Properties panel and sort the Markups list by subject.
Count Measurements and the Markups List
Running totals for Counts appear in the Count column of the Markups list.
Note that Count measurement groups are automatically split up by page. Giving each of the groups the same, easily identifiable Subject on the Properties panel will make it easier to get a total across multiple pages; just sort the Markups list by Subject.
Changing a Count Measurement's Appearance
The appearance of a Count measurement is configurable, including the symbol used as well as its color, scale, and opacity.
To change the appearance of a Count measurement, select it and click the 
Properties panel. Several properties will also be available on the Properties toolbar when the markup is selected.
Appearance Properties
Scale: Sets the size of the Count symbol.
Color: Sets the color of the Count symbol.
Opacity: Sets the opacity of the Count symbol from 0 (invisible) to 100 (opaque).
Symbol: Determines the symbol placed on the PDF to represent the Count.
