64 bit problems (again)

[Miller, James V (CRD)]

What release of vtk are you using?

I made a pass through the readers and writers when we started to build on a 64bit platform.  So I am
not aware of any problems that I haven't already addressed.  I know the readers and writers were
affected.  I am not sure whether I had to make any changes to the XImageMapper.

Are you using 2.2, 2.3, a nightly release?

If a nightly release, please send the output of 

vtkVersion v
v GetVTKSourceVersion

This will allow me to check the files you mentioned against the repository.

Hi,

We are using VTK on different platforms and also on Digital Unix. I reported
earlier problems using long type variables which are implicitely assumed to have
a size of 4 bytes in the VTKXImageMapper.

Same problem now in the vtkTIFF{Reader and Writer}...
e.g. the function Swap4 get a long (==8 bytes) as input but only swaps 4
fread is done with sizeof(long) to read info from TIFF header which is stored
as a 4 byte int.

Is there any chance that VTK will be 64 bit compliant ??
What's the reason of this "overwhelming" use of long type variables ?

I can provide you with the adapted versions of vtkXImageMapper, vtkTIFFReader and vtkTIFFWriter.
I assume comparable problems in vtkBMP{Reader, Writer}  but till now never had to use this code.

Bye
