Notable Changes in Igor Pro 10.03

IGOR APPLICATION

NEW FEATURES

• The igorpro.fn submodule now supports calling Igor user functions defined in independent or regular modules.

  For the independent module function Analysis#processData() defined in Igor:

  #pragma independentModule = Analysis
  
  function processData()
    ...
    return result
  end
  

   

  # In Python, call the 'processData' function in the 'Analysis' independent module
  result = igorpro.fn.analysis.processData()
  

   

• The prefix and postfix increment (++) and decrement (--) operators can now be applied to global variable references in Igor procedure code. For example:

  Function test()
    NVAR globalNumber = root:myGlobalVar
    globalNumber = 10
  
    // Postfix increment
    Variable result = globalNumber++  // result = 10; globalNumber = 11
    
    // Prefix decrement
    result = --globalNumber           // result = 9; globalNumber = 9
  End
  

   

• Added a key binding to temporarily override snapping to drawing guides. Hold down Caps Lock while dragging an object to suspend snap-to-guide.

CHANGED BEHAVIOR

• Improved ImageThreshold Fuzzy threshold methods (/M=4 and /M=5) to provide better threshold values.
• The Find in All Windows command now uses the text under the cursor as the initial search string, matching the behavior of the regular Find command.

BUG FIXES

• Fixed a bug in MLLoadWave where the operation's output variables where not set correctly when run from a user function.
• Fixed a crash that could occur when drawing certain TIFF images (1 bit per pixel with LZW compression) in a page layout.
• Fixed several problems interacting with draw object handles that extend beyond the page boundary in a page layout. Resizing and moving with those handles, cursor changes, and right-click contextual menus now work in the margin area. This was also broken in Igor Pro 9.
• Fixed incorrect handle highlighting (and a crash) when changing the layout expansion while drawing or editing polygons and Beziers in a page layout.
• Fixed a spurious compile error that occurred when a structure variable expression was combined with another expression.
• Fixed a spurious compile error involving a FUNCREF and a global string variable that have the same name.
• Fixed a bug in SplitWave when splitting a wave-reference wave or a data folder-reference wave (a wave whose elements are WAVE or DFREF references). Only the first output wave received the correct references; the second and subsequent output waves had their references written to the wrong positions, so they contained incorrect or missing references. Numeric and text waves were not affected.
• Fixed a crash that could occur when free data folders stored in a thread queue were prematurely disposed.
• Fixed a bug in Histogram where the square-root-of-counts destination wave specified with /N=destWave was created with the wrong name and as single precision instead of double precision.
• KMeans now sets the documented V_flag output variable.
• Fixed a bug in FindValue where the /RMD range was limited incorrectly for complex waves.
• Fixed a bug in FindDuplicates that produced incorrect results for complex waves when the tolerance was zero.
• Fixed a bug in ImageTransform where input waves used by the putRow and putCol keywords were not protected and could be overwritten when /DEST was used.
• Improved the error message reported when an unknown or inappropriate name is used where a number is expected. The message is now clearer instead of always reporting "expected number".

Procedures

• Multipeak Fitting.ipf - The Multipeak Fit GUI now computes derived peak values (such as FWHM and peak area) for each peak after a fit. The results are stored in new "Peak N CoefsDER" waves alongside the existing peak coefficient waves.
• Multipeak Fitting.ipf - The Estimate Now button now bases its estimates on the currently visible graph range, so zooming in or out before clicking Estimate Now changes the result. Previously the estimate ignored the displayed range.
• Multipeak Fitting.ipf - Fixed a regression where finding peaks in the residuals could report many spurious peaks when the peaks are negative. This was visible in example 3 of the Multipeak Fit Demo experiment.
• Split Axis.ipf - The Split Axis package now copies error bars onto the split traces.
