this may be the source of your issues, I thought that if you don't
return 1 from this function PV will assume your reader is not the
right one and skip it(ie never call SetFileName). But if that were
really true I don't get how RequestData is getting called...<div><div class="h5"><br>

<div>awesome, thanks, that did it.<br>

One more question. Is there a way to debug
the FileName aspect of the reader. I can't
figure out how it's supposed to get set.
The only way I can get the image to show
is by hard <br>
coding it within the RequestData()
function.<br>

Hi Kevin.<br>
<br>
Your RequestInformation looks a
little bare. Unless things have
changed recently, you might need to
set WHOLE_EXTENT, ORIGIN, SPACING,
CAN_PRODUCE_SUB_EXTENT keys there.
and if you support parallel IO honor
the requested extent in RequestData.<br>

like these functions from
the header file (of the
reader):<br>

vtkGetStringMacro(FileName);<br>
vtkSetStringMacro(FileName);<br>
