[vtkusers] is compressed data supported?

[Andy Cedilnik]

Hi All,

I don't think vtkZLibDataCompressor will do exactly what you want. You
can use it to decompress file, but you will somehow have to get that
into whatever reader you need, which is not supported. 

So, if you have let say raw image data, then you can read file, use data
compressor to decompress and create the image data. If you need some
other reader, then you will have to write your own (subclass) and use
gzopen to open file.
