[IGSTK-Developers] Some recent bugs and changes

[Patrick Cheng]

Hi guys,

I recently submit several bugs. They are:

1.----------------------------------------------------------------------
BUG: 2688. ImageSpatialObjectRepresentation class bug, uninitialized 
memory access (I put in a fixed already)
http://public.kitware.com/Bug/bug.php?op=show&bugid=2688&pos=3

( Kevin Jr, Could you please have a look at this one? This one relates 
to the interaction between the ImageSpatialObjectRepresentation and 
View. ImageSpatialObjectRepresentation needs a input: 
ImageSpatialObject, and has to be added to the View for display.
  Some principals I followed here are:
1. When there is no image available, and we add the representation to 
View, we should not connect the VTK pipeline. When there is a valid 
image, then we should connect the pipeline.
2. Every time we get a new image, we should connect the pipeline again.
3. The order of set image and add to view should not matter
)

2.----------------------------------------------------------------------
BUG: 2667. delete vtkObject ERROR messages in tests
http://public.kitware.com/Bug/bug.php?op=show&bugid=2667&pos=5

Failed test can be found at:
http://public.kitware.com/IGSTK/Sites/camelot.kitware/Linux-g++-3.4+Loopback/20060106-1308-Experimental/Test.html
( Kevin Jr, could you also take a look at this one? The VTK reference 
counting problems)

3.----------------------------------------------------------------------
BUG: 2689 Representation class's Copy() method should copy it's state 
machine and current states
http://public.kitware.com/Bug/bug.php?op=show&bugid=2689&pos=2

4.----------------------------------------------------------------------
BUG: 2695 Update Extend Error with the ImageReader
http://public.kitware.com/Bug/bug.php?op=show&bugid=2695&pos=0

Testing code to expose this problem has been added to the end of
­igstkCTImageSpatialObjectReadingAndRepresentationTest
The error msg:
##################################################################
ERROR: In 
/home/ibanez/src/VTK/Filtering/vtkStreamingDemandDrivenPipeline.cxx, 
line 624
vtkImageImportExecutive (0x9fc8250): The update extent specified in 
the information for output port 0 on algorithm 
vtkImageImport(0x9fc7f90) is 0 511 0 511 4 4, which is outside the 
whole extent 0 511 0 511 0 1.
###################################################################
(I have a solution for this one, by changing IGSTK code. But 
essentially this is a bug from vtkImageImporter and vtkStreamPipeline, 
so it might need more investigation.
)

5.----------------------------------------------------------------------
Also fixed some remaining bugs with removing FLTK. and clean out the 
testing part of the IGSTK, so that it will evaluate the IGSTK_USE_FLTK 
  and IGSTK_DATA_ROOT variable to decide whether to add a test or not.


Sorry for the messy email.
