And fix the tiff writer to put out a page with decent strips.

I think it's just as much the fault of the writer as it is the reader. In 
this case, as you mention, if the reader can read it scanline at a time then 
it 'could' read it. However, I say 'could'. If the reader needed random 
access to the file, then it can't (unless it caches it - which is 
essentially converting it to a degree to a 'strip' based method, even if 
that's scanline). OK - it could in this case 'cause the file is not 
compressed. However, if it were compressed the file would be in the same 
'mess'.

Writing a certain number of strips is so easy, that it's pure laziness on 
the part of the writer in my opinion.

Anyone who outputs a single strip tiff file should be shot.

Andy.
