keyboard_arrow_downMeasure area distance & perimeter in PDF with JavaScript
This JavaScript sample lets you calculate area dimensions, measure between lines or trace perimeters in PDFs. The scale of measurement can be customized based on requirements and calculations are displayed as a comment annotation. This functionality is commonly used in construction software to measure the amount of material required during 'Take-off'. This sample works on all browsers (including IE10) and mobile devices without using plug-ins. To see an example visit Measurement tools demo.
