[ITK] How to check the functions in the ITK documentation

[Michka Popoff]

Hi

I merged your two questions in one topic, so I can answer the two at once.

In the class ImageFileReader, there is no SetFileName method. But the documentation states:
This source object is a general filter to read data from a variety of file formats. It works with a ImageIOBase subclass to actually do the reading of the data.

So if you go the ImageIOBase [1] class definition, you will find the SetFileName method. This can be confusing at the beginning, but when you don’t find a method somewhere (and this is often the case for most of projects you’ll find around, not only ITK), think to look at the parent class and the child/subclass. Often the methods are defined somewhere else.


For the Update() call, this is related to the ITK pipeline. Some detailed description can be found here [2]. There is also one article here [3] that is more readable, or there is a section (13.3) in the ITK software guide here [4].

Finally, we have a nice set of examples here [5] which show you how to use the ITK pipeline. This should help you getting started.

I thought of looking for the functions that come under that class here, but couldn't find that "SetFileName" function. Am I searching in the wrong place?
