4.4.3 Applying operations to objects

There are three ways you can apply image processing operations to objects in your workspace:

  1. Select the object you want to apply the operation to by single-left-clicking on the object name. When you single-click, the object name will change colour to show that it is selected, and nip will display the name of the selected object in the bottom right corner of the main window (this is useful if the selected object is scrolled off the edge of the window).

    You can select additional objects with Ctrl-left-click and Shift-left-click. This is necessary if you want to use an image processing operation that takes more than one argument.

    Once you have selected the rows (maybe in the right order), click on the processing operation you want from the menu down the right of the screen.

  2. If no objects are selected when you click on an image processing operation, nip uses the bottom few items (as many as are needed by the operation) in the current column. If the last few objects are the wrong type for the operation selected an error message will be returned.

  3. You can also type your formula directly into the expresion entry line at the bottom of the selected column. Chapter 6 describes the syntax in detail, but it's approximately C.

To apply the same operation to a number of rows, use Edit=>Group and Edit=>Ungroup.
