How do I create an image tool ?

With few exceptions, in order to perform a function on an image, it must first have a tool associated with it. To create an image tool when an AIPS++ image already exists (e.g. co.image), you basically follow the same steps as in the preceeding section (§ 10.2, p. ). However, instead of selecting ``imagefromfits,'' select ``image'' under ``image basic constructors'' as illustrated below:

1. Again, go to the `Manager' display in the Tool Manager GUI, and make the following selections:

   
   

   Package	Module	Tool		Constructor
   general	images	image	Create	image
   Don't understand this table? See § 3.2

   
   

2. Enter the following constructor parameters:

   Constructor: image
   Parameter	Sample Value	What it means
   toolname	myimage	Use these names for test data; otherwise create your own.
   infile	co.image	The name of the input image file

   After entering the above parameters,
   press Create.

This replaces the ``image'' tool button with ``image:myimage'' in the tool manager GUI. The Analysis functions associated with this tool now appear on the left side.

If unsuccessful, a warning message will appear and a red X may replace the green check mark to the right of the problem entry.
