Workspace
This area displays the objects (images, numbers and so on) which are currently loaded into nip2. The workspace is divided into columns of objects which each behave rather like windows: they can be moved around, folded away, loaded, saved and deleted.

Current column
One column is the current column. This is the column to which all new objects are added. Single-left-clicking on the title bar of a column makes that the current column. See §4.4.1.

File, Edit, View
Use the File menu to create or save workspaces, to open workspaces or load other objects into this workspace, to merge workspaces and to recover after crashes (loads last automatically saved workspace). Use the Edit menu to select, group, delete and duplicate sets of objects. Use View to show and hide elements of the main window, and to set the object view mode.

Toolkits
This menu contains all of the image processing functions which are currently loaded into nip2. They are generally grouped by object type: all of the operations on matricies are under Toolkits / Matrix, for example.

If you select one of these image processing operations, nip2 will apply that operation to the bottom few items in the current column (however many are necessary -- two items for Math / Arithmetic / Add, for example), or alternatively, if you have selected some objects explicitly, it will try to apply the operation to the selected objects. See §4.4.3. As you move the mouse pointer over menu items nip2 tries to display some helpful information about the operation, including the number and type of arguments the operation expects.

Toolkit Browser
This side panel shows all the image processing operations again, but this time as a large flat list you can easily browse. Type into the search box at the top to filter operations by keyword. Doubleclick on an item to activate it.

Free space
This displays the amount of disc space you have left in your temporary file area. See §A if you want to change the directory nip2 uses to store temporary files.

If you left-click on the label, it changes to display the space nip2 has free internally for performing calculations. You can change this limit in the Preferences workspace. Click again to switch back to disc free.

If you have objects selected, this area changes to show the names of the selected objects.

Status bar
As you move the mouse pointer about the window, this bar tries to display useful information about the thing you are pointing at.
