Overview

The ComPDF SDK supports drawing annotations of lines, polylines, and polygons with measurement information in PDF documents to measure distances, perimeters, and areas of specified parts in the document. By setting a scale, such as specifying that one inch on the PDF document corresponds to one foot in actual distance, you can measure the actual dimensions of objects in architectural design drawings.
