Added capability to make an image transparent only where it is black, to facilitate superimpositioning of images.
Version 126.96.36.199. (released 25 May 2004)Added capability to Sort-by-Shape according to the measurements of an Analysis. The computed similarity metric is the sum of the squared differences between corresponding measurements.

Version 188.8.131.52. (released 11 February 2004)Updated 'Send to PowerPoint' for better results.
Corrected bug in importing of TIFF files.
Added VIFF file support (uncompressed).
Minor improvements and bug fixes.
Version 184.108.40.206. (released 30 December 2003)Supports Procrustes superimposition and Principal Component Analysis. Calculates Principal Components and includes a PCA viewer to display the effect of the Principal Components on shape.
Supports transparency of images and interactive rotation of images. These functions allow structural superimposition.
Added resampling capability for reducing the resolution of images.
Added function to export the tracings and images to an image file.
Updated Align Tracing function. After aligning tracing and image, it is now possible to automatically adjust the soft tissue points, if they do not correspond to the image exactly.
Measurements are dynamically updated during VTO movements.
Enhanced Select tool to enable translation and rotation without switching to other tools.
Moving the Select tool over the measurements will show a hint drawing, demonstrating which angle or distance is represented by the measurement.
It is now possible to hide all points during digitization, so that user is not biased when performing multiple digitizations.
Added Convert Type function to convert radiographs from one Type to another.
Prepared internationalization and added Greek language files.
Corrected a number of bugs. Numerous small improvements.
Version 220.127.116.11. (released 25 March 2003)Updated Brightness/Contrast/Gamma adjustment for faster and better results.
Added capability for multi-pass scanning for reduction of image noise. Radiographs can be scanned up to 5 times and the average of the scans is used, thus reducing noise from the scanner's CCD.
Version 18.104.22.168. (released March 2003)Added Extended Analysis that can show and print the tracings and measurements of up to four radiographs in various ways for easy comparison. Can be customized extensively.
Upgraded printing options for Text and Tracing analyses.
Export function can now export point coordinates as well. Also, data can be sent directly to Excel, instead of an intermediate text file.
Added Hint Graphic when digitizing radiographs. The user-definable graphic can appear in order to provide visual feedback for better localization of points.
Added Dynamic Edge Lock orientation. Now the orientation of the edge-lock cursor can change according to the position of the digitizing mouse. Very useful for locating such points as the tangent to the mandibular border.
Added capability to export measurements and tracing directly to Excel, Word and PowerPoint, instead of going through the Copy/Paste method.
Added capability to scan at 12-bit and 16-bit colour depth.
Added capability to read 12-bit TIFF files. These are converted to 8-bit for display.
Added capability to read certain types of DICOM files (explicit, little-endian, native format, monochrome files). Gives user the option to import the name, date of birth and other patient information from the DICOM file, if it exists. More DICOM file formats will be added in the future.
Added option to colourise the radiograph image, by applying Look-up Table files (LUT).
Added Levels function that allows adjustment of the image based on the image histogram. Gamma adjustment is also available.
Now Viewbox can act as a COM server for integration with other software (e.g. Practice management software).
Changed menu to look like the Windows XP menus.
Numerous small changes in the menus, toolbars and dialogs.
Numerous internal changes for better performance. Corrected a number of bugs including:
Viewbox would not close if the INI file was read-only or user did not have write access.
Duplicate function sometimes did not work correctly.
Export function did not always write Headers correctly.
