Features

• SimpleFilter's update/push to slicer is not quite right.

Here is the code: https://github.com/SimpleITK/SlicerSimpleFilters/blob/master/SimpleFilters/SimpleFilters.py#L288-L297

And here is the MRML combo box which creates the output node:

https://github.com/SimpleITK/SlicerSimpleFilters/blob/master/SimpleFilters/SimpleFilters.py#L568-L583

The first time a filter is run every thing appears OK. The filter runs. The new node is selected for the background node, and it's displayed. However, when a filter is run a second time to the same output, The filter runs, and the display still has the old BG image. And the following error is displayed a multitude of times:

ERROR: In /scratch/blowekamp/build/Slicer/VTK/Filtering/vtkDemandDrivenPipeline.cxx, line 727
vtkStreamingDemandDrivenPipeline (0x7fc0c94d1640): Input port 0 of algorithm vtkImageResliceMask(0x7fc0c910c050) has 0 connections but is not optional.

• When should output be considered a label map?
  • Add a check box?
  • When input is?
• Beautify filter name: space separated and trimmed of "ImageFilter" suffix
• Add Cast filter, with manual json description
• Improve the image filter selector with ctkMenuComboBox
  • Add ITK groups and/or module for hierarchy
• How to handle N-ary input filters?
• Display filter measurements after completion
• Handle image type produced by SimpleITK that can't be handled by Slicer
  • ITK's RLE LabelMaps, complex pixel, and VectorImages....
• Include detailed Doxygen documentation? Button, tab?
• Link to ITK Doxygen?
• Add progress reporting, and ability to cancel.
  • Pending progress reporting in SimpleITK
