Overview

ComPDFKit PDF SDK supports drawing lines, polylines, and polygons with measurement information in PDF documents. This allows measuring distances, perimeters, and areas of specified sections in the document. By setting a scale factor, for example, defining one inch on the PDF document to correspond to one foot in actual distance, you can measure the actual dimensions of objects in architectural design drawings.
