Changes from Stradwin 5.3 to 5.4
Changes relating to surfaces and drawing
There is a new option to export summary textual information about contours and surfaces, for instance area, perimeter and average data value within each contour.
Imported surfaces can be transformed using an ITK .euler file as well as .mtx.
Use of zero opacity disables display of contours in reslices as well as the 3D window.
The 'sparse contours' option has been split into 'connect object' and 'holes'.
It is now possible to turn all threshold regions into surfaces, not just connected ones. This uses much less memory, useful for working with very large data sets.
A bug involving use of multiple surface patches has been fixed.
The contour simplification code has been improved for even greater precision.
Considerable automatic checking and correction for self-intersecting contours, or mutually overlapping contours, has been added. Landmarks are placed in the rare occasion that contours can't be fixed.
Changes related to Cortical Bone Mapping
There is a new 'reject distance above' slider when creating new cortical surfaces from measurements, to avoid large differences from the initial surface.
The Endo CBM v2 implementation is considerably more robust.
Changes to scripts and movies
The 'save movie' buttons have now been moved into scripts, and there is much more flexibility for rotating / moving / zooming a window during movie creation.
Script commands now do not need 'RES_' at the start, though backwards compatibility has been preserved.
Cursors and other key presses
Cursor keys now work in most windows to move and rotate by set amounts.
Cursor keys also work over trackgrids and trackballs.
Discrete cursor movement options added to GUI options menu.
There are some changes to key presses, plus additional orientation setting in 3D.
The DICOM GUI now has calibration values and a Gaussian smoothing filter
There is a new basic .nrrd format conversion for input data.
A bug in the reslice code for very precisely orthogonal reslices has been fixed.
Initialisation of a fastrak is slightly more reliable by disabling continuous reporting.
Erasing a large number of contours in the 3D window is more efficient (slower delay).
Resolution values in TIFF files are handled slightly better.
