Igor XOP Toolkit

The XOP Toolkit is an add-on package that allows C and C++ programmers to extend Igor Pro. The toolkit has been used by WaveMetrics and by hundreds of Igor users to add data acquisition, manipulation and analysis features to Igor Pro.

"XOP" stands for "external operation." Originally XOPs were intended only to allow adding command-line operations to Igor. Now XOPs can add operations, functions, menus, dialogs and windows. XOPs are also sometimes called "Igor extensions."

The XOP Toolkit consists of a library of "XOPSupport" routines that allow an XOP to communicate with Igor, a comprehensive manual, as well as source code and project files for many sample XOPs.

XOP Toolkit 7 can create XOPs for Igor Pro 6.20 or later.

The XOP Toolkit supports development for Mac OS X, Windows 7, Windows 8, and Windows 10.

The XOP Toolkit is available as an electronic download. It includes a PDF manual.

To create an XOP, you start with sample XOP source code supplied with the Toolkit. After modifying the sample, you compile it to produce the executable XOP file. To activate an XOP, you put an alias (Macintosh) or shortcut (Windows) for the XOP file in the Igor Extensions folder in your Igor Pro folder.
