## Operations Menu

The Operations menu contains commands for performing operations on the selected data. Contents of the Operations menu vary from iTool to iTool.

Table A-7: The Operations Menu
Menu Selection | Function
--- | ---
Operations Browser | Displays a hierarchical nested list of all tools in the menus and toolbars. See The Operations Browser for details.
Macros | Selections related to iTool's macros. Run Macro: Select to run a macro. Start Recording: Select to begin recording a macro. Stop Recording: Select to cease macro recording. Macro Editor: Select to bring up the Macro Editor dialog.
Statistics | Computes the statistical properties of the selected item(s), and displays the results in a separate dialog. See Displaying Statistics for details.
Histogram | Displays a histogram plot of the selected data. See Plotting a Histogram for details.
Filter | Choose from these options: Convolution Median Smooth See Filtering. {Additional filters vary depending on the iTool selected.}
Rotate |
Rotate Left Rotate Right Rotate by Angle | Rotate the selected data space left 90°. Rotate the selected data space right 90°. Specify the number of degrees to rotate the selected data space. Note - Rotate by Angle is absolute and always rotates relative to the original X-Y coordinate system for 2D visualizations. For 3D visualizations, Rotate by Angle is relative and does not remember the current rotation angle.
Transform | Resample — Resample the selected data using parameters specified in Resample property settings. Rotate Data — Rotate the data within the visualization by a specified number of degrees without affecting the rest of the data space. Scale Data — Scale the selected object by a specified scale factor. See Transformations for details. {Additional transformations vary depending on the iTool selected.}
Morph | Choose from the following options: Dilate is commonly known as "fill", "expand", or "grow." It can be used to fill "holes" of a size equal to or smaller than the structuring element. Erode does to the background what dilation does to the foreground. Given an image and a structuring element, erode can be used to remove islands smaller than the structuring element. Morph open is simply an erosion operation followed by a dilation operation. Applying morph open more than once produces no further effect. Morph close is simply a dilation operation followed by an erosion operation. Applying morph close more than once produces no further effect. Morph gradient is the subtraction of an eroded version of the original image from a dilated version of the original image. Morph tophat is implemented by first applying the opening operator to the original image, then subtracting the result from the original image. Applying tophat shows the bright peaks within the image. See Morphing for details.
