Digitizing Printed Graphs Using C++

Abstract

Occasionally, tabulated data is required where only graphical data is available. In such cases, obtaining tabulated data by hand can be time consuming. The C++ code described in this report provides a method for converting from graphical to tabulated data. It records mouse clicks to capture axis and graph information and then performs a transformation from screen coordinates to graph coordinates. The origin of the graph need not be present, and the axes can either be linear or logarithmic. Axes that are rotated and/or skewed are accounted for.
