<P><FONT size=2>Hello all,<BR>I'm using vtk under windows and I'm getting some
weird behavior. My data sets are around 120MB in XML. I'm using
vtkXMLImageDataReader to read them in. They're then passed through
vtkImageData, vtkImageChangeInformation and vtkImageReslice before being
turned into vtk2DActors. At this point, my memory usage is around 500MB
(the above pipeline actually exists three times and there's some other stuff
in there). I tried cleaning this up with the DataReleaseFlag to no
avail. However when I minimize my application, the memory goes
down to virtually nothing. Then when I maximize it again, the memory is
very moderate (~200MB) and barely changes at all. Though this doesn't
occur when I move the app to the background (switch to another open
app). What exactly is going on at this point? Is vtk caching some
image data that gets released when the app is minimized? Is there a way
to manually do whatever is being done?<BR><BR>Thanks in advance!<BR>Joe</FONT>
