Release Notes

Version 3.1 (14 August 2026)

• Small bug fix. Synchronized display not registering correctly due to HeaderOffset, RegsitrationCellX and RegistrationCellY not being present in the .ers file. These parameters now default to zero if not present.

Version 3.0 (3 August 2026)

• Fixed bug relating to updating .ers files.

• Added grid rotation and unrotation functionality.

• Updated the User Manual.

Version 2.3 (18 May 2026)

• Improved Zoom To functionality - now zooms to not-null extent of grid.

• Fixed a bug relating to Zoom/Pan button being partially obscured. 

• Improved memory management. Users can set a Memory Cache - size set in Set Aliases And Parameters. Cached grids greatly improve processing times for Trim Grid Overlaps and Get Overlaps.

• Fixed error due to shared states with 2 View Grid instances open at the same time.

• Grids no longer have to have the same size and extents to be displayed in the display panels at the same time.  The display panels now share a reference system and grid images are spatially synchronized. Zooming and panning on either panel results in both panels being zoomed/panned in unison.

• Updated the user manual.

Version 2.2 (30 March 2026)

• Fixed a bug relating to program crashing when a required file is in use by another process. Program now gives an error message and aborts the current process only.

• Fixed a bug relating to data entry to text boxes. Also, significantly hardened the software with respect to directory and file name entry via a text box or control file. 

• Updated the user manual.

Version 2.1  (9 March 2026)

• Parallelized several processes. Modified worker methods to ensure thread safety. More efficient rendering of images.

Version 2.0  (26 January 2026)

• Major update. Almost all tools have been optimized for speed. Critical bugs fixed in calculation of absolute shift/scales. Control line, base grid and "Shift Only" constraints are now "hard constraints" in the inversion.  Rendering of images optimized. Code parallelized where possible.

Version 1.0.4  (5 November 2025)

• Reintroduced an "invariant" decimal culture. Irrespective of a computer's Language and Region settings, GridMerge will now always require (and use) a period (.) to separate the integer and fractional parts of real numbers. The use of a comma (,) is not allowed.

• Updated the User Manual.

Version 1.0.3  (25 April 2025)

• Added a capability to specify Base Grids and Shift-Only Grids using the Set Aliases and Parameters window. Previously this could only be done using a control file.

• Updated the User Manual.

Version 1.0.2  (19 March 2025)

• Fixed a second bug relating to the way other "cultures" read decimal numbers (use of commas to separate integer and fractional parts of real numbers).

• Updated the User Manual.
