Version3.3

Major enhancment links contour plot and profile plot.
Added current profile line indicator to contour plot. Linked contour plot and profile plot so that moving the profile angle moves the contour profile.
Displays error of pixel under contour plot cursor and move the profie angle to match and include that point.
Left click and drag creates a zoom rectanngle. Right click zooms out full size.

Tools menu. Added wavefront transforms to change size of wave front, to change input wave length, to flip wave front. Necessare to compare wave fronts from other users done at different settings

Tools menu. Added tilt vs astig analysis.

Added save Foucault and Ronchi images to the scan control.

Region editing. Pressing control key with shift and left button mouse moves all regions.

Preferences DFT. Added flip resulting analysis settings.

Remembers zoom to edge setting on load of new interferogram and in batch processing.

Moved progress bar for batch processing to the Batch dialog

File menu Added save current profile to a text file.

Corrected bug so that last used central obstruction outline is remembered correctly.

Corrected issue with contour plot and 3d plot which did not show as desired in report.

Corrected obstruction shown in profile plot

Inhibited asking about inverting wavefront during test stand removal process.

Enhanced test stand astig circle plot to show lines linking rotations 90 deg apart.

Enhanced test stand astig circle plot to pick a better circle fit algorithm when points are mostly on a line.

Fixed last outlines not being remembered correct when next igram is loaded and center outline was last selected.

Fixed bug that would not invert wave fronts.

Added dialog to configure size of contours in show all counters feature.

Corrected calculation of polar angle of atig value displays.

Batch feature. Changed review to save indiviual images instead of making a movie.

Version 3.1

• Version 3.1
• Improved outline finding algorithm by using Sobel filter.
• Fixed bug where 3.0 igrams were analyzed wrong for some image types. Should now agree with 2.2 for all image types.
