Can anyone please tell me why the TIFF reader allocates 8 bytes to each element?? This is resulting in very slow rendering of TIFF files and the inability to open larger ones.<br><br><span class="e" id="q_110ea929f2b80026_3">

1.4 GB. If ParaView was compiled for 32 bit then you may have reached its limit. I know on my own OS X machine with when ParaView gets much above 1GB of used RAM I should start praying.. <div><br></div><div>I don't pretend to know anything about memory management under any of the Operating Systems. In my naive world, even in 32 bit mode there should be at minimum about 2GB of Memory available, or 4GB if the memory pointer that is used is and unsigned 32 bit integer. That is in my own little world where I understand things. In the real world it doesn't work that way. Maybe someone can explain it to us.
