Project Releases

• The 'quit' panel does not appear anymore if no changes were done.
• Added image color / range controls for the output.
• Added support for log color display.
• Improved initial step-size calculation for small input data. The data is much more fine-grained now.
• Keyboard inputs are now tracked from the profile side-panel as well.
• Streamlined window hook function.
• The main graph can now be killed more easily in case of an error.
• Now the data can be pre-aligned in all dimensions via the '=' buttons.
• Code optimizations using the IPT tool (ver. 0.9) from BytePhysics. No errors or warnings for:
  ipt lint --exclude CodeStyleDefaultPragmas '.\Spectra Difference Generator.ipf'

• Added preset for averages.
• Slightly optimized panel style.
• Code optimizations using the IPT tool from BytePhysics.

• Fixed bug: Reference wave was sometimes not found when the source folder had changed.
• Fixed bug: Bad definition of color popups, which were problematic in Igor 8.

• Now the source wave is used to prepare the internal data, which properly accounts for changes to the source.
• Fixed bug: 2D profiles were not correctly calculated if the map contained NaNs.
• Optimized the size of the popup windows for the wave selection.

• Recreating old sessions is now more robust when the folder containing the data has been renamed.
• Results saved with the reference now take precedence over modified waves when loading settings.
• Fixed bug: Reference could not select waves with the same name as the source in a different folder.
• Upgraded wave selection to PopupWS panels (only Igor 9).
• Now the modified wave is saved next to the source wave, even if 'Use Ref. Name' is active.

• Fixed bug: Error message was displayed in the UI if no reference wave was present.
• Fixed bug: x and y scales were not applied correctly.
• Increased backwards compatibility with very old data.
• Connected X and Y scaling to the UI.
• Improved the help text of the UI.
• Fixed bug: The pin-baseline checkbox and keyboard shortcut did not result in the same outcome.
• Fixed bug: Pin baseline offsets had a rounding error with Gaussian smoothing enabled.
• Fixed bug: The offset value in the graph legend did not include the scaling factor.
• Reported offset values now include possible drifts caused by Gaussian smoothing.

• Fixed bug: The 'Quit' panel had the wrong size when a graph expansion was active.
• Fixed regression bug to work with older panel versions again.
• Optimized a few code segments related to mouse dragging.
• Removed minimum delta limit for y/z shifts and decreased the delta limit for x shifts, enabling more fine-grained shifts.
• Fixed bug: Reference wave updates were skipped too often.
• Fixed bug: Sessions were recreated from the first and not the last recording in case of multiple note entries.

• Changed modification info to a text box (instead of a legend).
• Fixed bug: WaveArithmeticErrorMsg() was not public.
• Fixed bug: Smoothing was broken in ver. 5.00.
• Fixed bug: Reference smoothing is now reapplied after selecting a different wave.
• Fixed bug: s.formula was not properly initialized.
• Fixed bug: Arithmetic calculation was not working when modWave or modRefWave were not specified as input.
• Fixed bug: Baseline only worked correctly with cursor A.
• Added option to extend the reference to the full range of the modified wave (limited to 1D for now).
• The version number is now written into the wave notes.

• Upgraded code to Igor 8.
• Implemented 2D wave support for WaveArithmeticKernel().
• doWaveArithmetic() (new function name for WaveArithmeticKernel()) outputs error codes instead of string messages.
• Added full 2D wave support to the user interface.
• Various bug-fixes and tweaks.
• Added support for custom arithmetic expressions.

• Fixed bug: The buttons of the inset panel could appear on unrelated windows in some circumstances.
• Fixed bug: Some buttons were not sized properly for Mac.
• Last version with Igor 6 compatibility.

• Fixed error when loading very small wave.
• Added percent-difference mode.
• Minor big-fixes and code improvements.

• Fixed wrong panel size for windows.
• Fixed bug: The arrows were reversed for some panel controls with negative delta scaling.
• Fixed bug: Out-of-range error could happen for reversed (negative delta) waves.
• Now multiple instances of the tool can be opened at the same time.
• Added support for keyboard-shortcut (and other future) settings via external text file.
• Improved backwards compatibility with older panels.
• Comparisons can now be generated via user code by invoking WaveArithmeticKernel().
• Axis split between comparison and result spectrum can now be dragged to a new position.
• Added controls to for selecting and saving additional data generated from the result.
• Added keyboard shortcuts for smoothing the input (home/end) and reference (alt or option plus home/end) waves.

• Improved edge behavior of the Gaussian smoothing (data edge are less likely to bulge).
• Moved all controls into an external panel.
• Added controls to directly set absolute X,Y, and scale values for changes.
• Now Background Pinning honors smoothing as well.

Fixes:

• Gauss convolution was not working well if data included NaNs.
• Now the smoothing value is also displayed in the legend.

Forgot to remove debug print command.

Added multiplication and division modes.
