Require a simple drawing to pdf on the fly. Drawing consists of two arcs (centre point and angles the same for both arcs), the ends of which are joined to each other by straight lines. The data will be in an xml file and consists of the 2 radii and angle. The xml file may have multiple sets of data and thus pdf may have the same number of pages. It is required that when the user prints from a page the drawing is printed at actual size
As an alternative to this method, the drawing may occur on the webpage with a button to print. The printed drawing must be actual size, the screen version need not be.
