[Radiance-general] super high res images

[Greg Ward]

Hi Jack,

Is there any reason you can't just render your large image straight 
off?  It will come out uncompressed, as the RLE algorithm in Radiance 
doesn't work for scanlines longer than 32K, but otherwise everything 
should work.  Are you getting some error along the way?  I just ran a 
test with pcompos, creating a 50K by 50K image.  It took 9 GBytes of 
disk space and took a few minutes to write out, but seemed OK 
otherwise.

Compositing tiles after filtering them separately will result in 
visible lines at the tile boundaries in some cases.
