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 `nip2` will display the name of the selected object at the left end of the status bar (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 (sometimes you need to select them in a certain order), click on the processing operation you want from the `Toolkits` menu.

2. If there are no objects selected when you click on an image processing operation, `nip2` uses the bottom few items (as many as are needed by the operation) in the current column.

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.
