<P>Hi guys,</P>
<P></P>
<P>I was wondering how MapServer handles raster data. I've seen the large list
of image formats that are supported, but what does MapServer do with the images
when it loads them up? Does it try and fit the whole image into memory? If this
is the case, what happens if say the image is 2GB and I have 512MB of memory,
will it continue to try and load the file into memory, causing (on windows) the
swap file to be used, or will it just not load the file into memory and call the
file from the disk when needed?</P>
<P></P>
<P>Thanks,</P>
