[Radiance-general] Re: Horizontal artifacts in large image

[Greg Ward]

Hi Mark,

Assuming it's the long integer wrapping as I suspect, you should  
download top-of-trunk and recompile to see if this is fixed.  Go to  
www.radiance-online.org and click on the "download Radiance" link under  
software.  Then, grab the "current experimental/bug-fixed version"  
called radiance-HEAD.tgz.  Rerun "rmake install" in src/common and  
src/rt and that should update rpict, rtrace, and rview.
