What's new in 10.3.1.30115
A new release of Igor Pro 10 is now available. A list of notable changes for this release is included below. Go to the Downloads page or select the Help→Updates for Igor Pro menu item within Igor Pro 10 to get the latest release. If you've reported an issue to us and we've told you it's been fixed, the fix will be included in this release, even if it's not mentioned below. 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. …

CHANGED BEHAVIOR - The /UNATTENDED command line flag now skips the license activation dialog. - In 10.01, bitwise operators (&, |, and %^) returned incorrect large negative values when either operand was NaN. Bitwise operators are now defined to treat NaN, Inf, and -Inf operands as 0, matching the behavior in Igor 9 and 10.00. BUG FIXES - Fixed a bug (introduced in 10.01) where layout draw objects selected a phantom object after drawing. - FuncFit and FuncFitMD now support user-defined fit functions with complex independent variables in multidimensional curve fitting. - Fixed a Qt library bug that resulted in a crash/exception during startup on machines running old versions of Windows 10. - Fixed a crash in FuncFit when the fit function had no parameters. - Fixed line continuation anomalies in the compiler. …
