One more question: where do you derive your reader from (maybe the
parent class sets something for you)?

Thanks Mike, but this is exactly what I have.
Are you sure you see both bounds and extents in Information?

Not sure if it is any help but here is a code snippet from my own
HDF5
image reader code:
outInfo->Set( vtkDataObject::ORIGIN(), DataOrigin, 3 );
outInfo->Set( vtkDataObject::SPACING(), DataSpacing, 3 );
this->DataExtent[0] = this->DataExtent[2] = this->DataExtent[4] =
0;
this->DataExtent[1] = xDim-1;
this->DataExtent[3] = yDim-1;
this->DataExtent[5] = zDim-1;
outInfo->Set( vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),
DataExtent, 6 );
outInfo->Set( vtkStreamingDemandDrivenPipeline::UPDATE_EXTENT(),
DataExtent, 6 );

What else then WHOLE_EXTENT, UPDATE_EXTENT and SetExtent and do I
have
to fill in RequestInformation/RequestData of my plugin reader
(derived
from vtkImageAlgorithm) in order for Paraview to see the dataset's
extents? Only bounds are displayed in the Information tab, while for
native file formats there is also extents. But when I save the
file in
legacy format for a test the extent is written correctly, so it WAS
known to Paraview, only not displayed properly. What is wrong?
