Abstract
Recovering data points from scanned or photocopied graphs by hand is time consuming, prone to error, and it requires patience and a steady hand. An alternative is to use g3data-a program that reads many common image file types and allows accurate estimation of data point coordinates from the graphs contained in these files. Limits of the software are discussed, and validation of its accuracy using graphs with known data values is presented.Mesh：
