[ITK] [ITK-users] TileImageFilter SideBySide

[Michka Popoff]

Hi

Going the way described in the CreateVolume example is the way to go.

Why did you uncomment the DisconnectPipeline() call and Update() call in the for loop ? They need to stay there, else you will always use the last image.
That’s why you see the same image, the single update call will be triggered at the end of the script and read only one image.

You don’t need to call tileFilter->Update(), you can remove this line. The writer->Update() will take care of the pipeline update.
As a bonus, you may wrap your writer->Update() call, to fetch errors at the end of the pipeline:

  try
    {
    writer->Update();
    }
  catch( itk::ExceptionObject & error )
    {
    std::cerr << "Error: " << error << std::endl;
    return EXIT_FAILURE;
    }

I made a little Python prototype, the syntax is a little bit different than in C++ but it gives you the main idea.

So, I tried doing a for loop which didn't work exactly how I wanted it to work. I would like the program to take any amount of images and output them side by side , any ideas? The attachment shows the for loop I used similar to TileImageFilter CreateVolume example however when I use it for some odd reason only one image is being display side by side multiple times.
