Enabled Acceletators
Ctrl+   :   Zoom In
Ctrl-   :    Zoom Out

Added the "Forward only" option for MagTrace so the new snapping position is only forward with the respect to the vector between the previous fixed point and the current user specified position.

Enabled the ViewFilter on the Parametric map image type volume.

Polyline\Spline control point hand shape: changed to semitransparent circle:

FireVoxel  Build 212 is released.

Implemented the FVX-file format Load\Save  incorporating the Splines\Polylines.

Polygon control points: change the style to the semitransparent filled rectangle.

This also solves the problem when the contour is copied,
resnapped. In previous version two points were snapped to the same coordinates, so the control point were becoming invisible.

Spline\Polyline entities: fixed the defect when the control point is selected, moved outside the document area and becomes unreachable.

Added the menu item   MainMenu>Trace>MagTrace

Implemented a support function to output the Edges used by MagTrace for the current slice.
Currently selected MagTrace parameters are used so it is a 1-click operation.

Corrected the "HitTest" on mouse click over the Spline entity.

Corrected the defect for the HitTest mouse click on the polyline.

Modified the ToolTip for the "Width\Level" button of the Main toolbar.

Added   "MainMenu>Trace>Application specific settings" ability for {Femur,Hippocampus} applications.

MagTrace tool: implemented 2 new UI-level functions
a) Snap Selection to Image
b) Copy from adjacent slice and Snap to image.

MagTrace on Hippocampus.

First experiment:  To evaluate the quality of snapping, I used the supplied HC Roi as the guidance.  I clicked precisely on the boundary of the HC-ROI and let the software to adjust the position.
Attached screenshot shows the snapped points, without any manual further corrections.
Note: the snapping was performed on x3 upsampled resolution (EMD\Radial\2.2).

MagTrace:  Restart tracing> fixed the Bug when user had polyline selected on a different slice from currently  MagTrace operational slice.

FireVoxel Build 211 is released.

1.  First version and user interface for the MagTrace semi-automatic tracing functionality.

MagTrace tool:  implemented functionality to resume the tracing of the existing Spline
a) Select the desired spline
b) Press MagTrace button.  Operation will resume from the last point.

Magtrace tool:  prevented the "Double entry" error when user presses snap button before the previous snap operation is finished.
