It sounds like you might have a virus on your machine. So, we think this program code may be useful when you deal with lines and big arrays of points.I'd try the method "Try to restore the clipboard contents from the registry" which is the second one listed in this post: This allows you to save your work, and return to it later. You also have an opportunity to save the Workspace. You may use Clipboard to output data or a special procedure 'Export to text file'. To digitize area use Operations →Digitize area menu. You can also make the grid be shifted in such a way, that it will pass through a specific X (or Y) value. You can choose the type of grid (X grid or Y grid), and set the distance between grid lines. Data points are set at the intersection of grid with the line. This method works for any type of lines, including dashed lines. Digitize area: The second way is to set digitizing area. To choose starting point click left mouse button, or click right mouse button to additionally choose direction for line tracing. To trace the line use Operations =>Auto trace lines menu or context menu ('Auto trace lines' item). Choose the starting point, and the program will trace the line, stopping at it's end. Auto trace lines: This method is designed to digitize solid lines. GetData Graph Digitizer includes two algorithms for automatic digitizing. Main features of GetData Graph Digitizer are: - supported graphics formats are TIFF, JPEG, BMP and PCX - two algorithms for automatic digitizing - convenient manual digitizing - reorder tool for easy points reordering - save/open workspace, which allows to save the work and return to it later - obtained data can be exported to the clipboard - export to the formats: TXT (text file), XLS (MS Excel), XML, DXF (AutoCAD) and EPS (PostScript). GetData Graph Digitizer is a program for digitizing graphs, plots and maps. Program GETDATA Graph Digitizer (looks more suitable for our purposes. We managed to test some free available program codes. From our point of view including to the Exfor-Digitizer procedures of automatic or semi-automatic digitizing will allow to simplify significantly this process. Plots containing a great amount of points and solid lines are most complicated for digitizing. So we are rather interested in the development of different techniques of data digitizing. 90 percents of compilation in our center is obtained by data digitizing.
