Igor Pro® includes a powerful and full-featured structured programming language that you can use for automation of data import, file I/O, analysis, data acquisition, graphing, drawing, printing, and just about anything you can think of. You can add menus to the program and create control panels containing buttons, checkboxes, popup menus, and other controls to set parameters or display results.Igor Pro aids you in your programming tasks with syntax coloring.Igor Pro ships with many examples illustrating (among other things) peak fitting, signal processing, data acquisition, test automation, and graphing techniques.Programmability Complete built-in structured programming language Over 450 built-in functions and 400 built-in operations Many additional functions and operations supplied by XOPs and WaveMetrics-authored user procedures Symbolic debugger User-definable math and string functions All aspects of Igor Pro can be programmed Controllable by external scripting systems Syntax coloring in procedures Integrated help and documentation Search across multiple program source files Forum Support Gallery Igor Pro 9 Learn More Igor XOP Toolkit Learn More Igor NIDAQ Tools MX Learn More

Localized filters modify the value of each image pixel based on the value of pixels in its neighborhood. Localized filters are sometimes implemented as a convolution. Convolution filtering is a method for modifying the appearance of an image by convolving its pixel values with a transformation kernel. When the kernel is small it is more efficient to use the built-in operation MatrixConvolve. When the convolution kernel is relatively large it is more efficient to compute the convolution using the fast Fourier transform (FFT). A number of typicalconvolution kernels are implemented in the operation MatrixFilter which also contains a few localized (neighborhood) operators.Some of the MatrixFilter operators avg an nxn average filter. findEdges a 3x3 edge finding filter. Gauss a nxn Gaussian blur filter. GradXX 3x3 gradient filters with XX representing the two letters of the compass gradient direction. hybrid median a 5x5 ranked median filter. max sets the pixel value to the maximum value in the filter's size neighborhood. median a nxn median filter. min sets the pixel value to the minimum value in the filter's size neighborhood. ranked median user-defined ranked median filter. sharpen a 3x3 sharpening convolution filter. thin calculates image thining using neighborhood maps.

There are many tools and resources for learning Igor. They range from introductory tours to advanced help for specific topics.Guided TourThe Guided Tour is an essential introduction to Igor. You can access it through the Getting Started help file or through Igor's PDF manual. Both can be opened through Igor's Help menu.The Guided Tour is also available in video format.The Guided Tour is indispensable for getting started with Igor. We strongly recommend that you go through at least the first half of it.Example ExperimentsThese experiments are part of the standard Igor installation. You can browse the list of examples by running Igor and choosing Example Experiments from File Menu.The following tutorials, also accessible through the Example Experiments submenu of the File menu, guide you through specific subjects or techniques: 3D Graphics Tutorial Data Folder Tutorial Image Processing Tutorial User Fit Tutorial Using Igor Documentation X Scaling TutorialManualsThe Igor manual is available as a PDF document that you can access by choosing Manual from Igor's Help menu.The Igor manual is included in the Igor Pro demo. If you want to see the manual but don't want to install Igor, you can download it here.Igor XOP Toolkit ManualIgor Filter Design Lab ManualIgor NIDAQmx Tools ManualVideo TutorialsVideo tutorials for Igor can be found on the Video Tutorials web page.

Ranges.The BlackBody color table is designed to show the color of a heated "black body" (though not the brightness of that body) over the temperature range of 1,000 to 10,000 degrees Kelvin.The Spectrum color table is designed to show the color corresponding to the wavelength of visible light as measured in nanometers over the range of 380 to 780 nm.The SpectrumBlack color table does the same thing, but over the range of 355 to 830 nm. The fading to black is an attempt to indicate that the human eye loses the ability to perceive colors at the range extremities.The dBZ14 and dBZ21 color table are designed for displaying weather maps using standard National Weather Service radar colors and values.The LandAndSea, SeaLandAndFire, Relief, and PastelsMap color tables all have a sharp color transition which is intended to denote sea level.The LandAndSea and Relief tables have this transition at 50% of the range. You can put this transition at a value of 0 by setting the minimum value to the negative of the maximum value:ModifyImage imageName, ctab={-1000,1000,LandAndSea,0} // image plotColorScale/C/N=scale0 ctab={-1000,1000,LandAndSea,0} // colorscaleThe PastelsMap table has this transition at 2/3 of the range. You can put this transition at a value of 0 by setting the minimum value to twice the negative of the maximum value:ModifyImage imageName, ctab={-2000,1000,PastelsMap,0} // image plotColorScale/C/N=scale0 ctab={-2000,1000,PastelsMap,0} // colorscaleThis principle can be extended to the other color tables to position a specific color to a desired value. Some trial-and-error is to be expected.Note: The BlackBody, Spectrum, and SpectrumBlack color tables are based on algorithms from the Color Science web site.Reference: Wyszecki, Gunter, and W. S.

Local users of this computer" radio button. Click "Install License".Multi-user Server LicenseTo activate a multi-user "server license" for all local and remote users, including users running Igor over a network connection, the administrator should follow the same steps as for Multi-user Local License, except: (Windows only) Step 2. Don't forget to right-click the installed Igor.exe or Igor64.exe and choose "Run as administrator". Step 7. Choose the "Server license installation for local and remote users" radio button.After Installing Igor Pro 7We recommend that you do not modify any WaveMetrics-supplied procedure files, as your modifications will be lost when you update Igor.You may wish to enable additional Igor extensions. See Activating More Extensions for details.Electronic RegistrationYou can register your copy of Igor by selecting "About Igor Pro..." from the "Igor Pro" menu, clicking the "License..." button and then click the "Register Igor Online" button.Getting Started with Igor ProWe strongly recommend that you take the "Guided Tour of Igor" in the Getting Started manual. It will get you off on the right foot and will save you a lot of time in the long run.To get a feel for what Igor Pro can do, use the File→Example Experiments submenu to open several example experiments.Igor Pro has extensive and informative interactive help (called 'Igor Tips'). And check out the Help Browser: Choose "Igor Help Browser" in the Help menu.We recommend that users upgrading from Igor 6 see the "What's New In Igor Pro 7" help file; it explains the changes and additions since Igor Pro 6.Online ManualThis version of Igor Pro includes the full Igor Pro manual set as PDF (Adobe Portable Document Format) files copied to your hard disk during installation. They may be accessed from Igor's Help menu by choosing "Manual".To use the online manual you will need Adobe Reader 6.0 or later.Demos from WaveMetricsDemonstration versions of the Igor Filter Design Laboratory and NIDAQ Tools are installed into the "Product Demos" folder on your hard drive. They may be removed without affecting Igor's operation.For other product demos, visit More Igor Pro ExtensionsExtensions in the "More Extensions" and "More Extensions (64-bit)" folders are not available in Igor Pro until you activate them.See the "Activating Additional WaveMetrics Files" help topic in the Igor help for more information.Igor Programming TipsNew and experienced Igor programmers should check out: The Igor Pro Programming and Reference manual.
