DIGITIZE07

DIGITIZE07(filename) displays an image and allows the user to digitize points using the mouse, similar to MATLAB's built-in GINPUT and other digitizers available at Matlab Central's File Exchange.

The main new feature of this version is that points are draggable; this permits fine tuning of already digitized points using the zoom feature. Other features adopted from previous versions include:
- Import previously digitized points
- Export digitized points to the workspace or file
- Interactively change the marker color, size, and shape
- Pin digitized points (i.e. toggle draggable mode)
- Delete unwanted points by right-clicking on the point
- Fully interactive GUI: Errors are reported to dialog boxes rather than to the Workspace
