Image Cache
Select the amount of virtual RAM you would like to reserve
for the image cache. As images are displayed in
Oasis
Montaj
, an efficient access version of the image will be stored
in the cache if there is room. The cache copy of the image
greatly improves the performance of rendering the image when
zoom/pan/redraw operations are performed. If there is
insufficient room in the cache, the image will always be
rendered from the DAT interface, which is slower.
We recommend that you should set the image cache size to
about 4 times the largest images that you routinely work with.
Note that the image cache will be created in the GEOTEMP
directory, and there must be sufficient room to hold the cache
plus other Geosoft temporary files. The image cache should
not be more than 50% of the available room in GEOTEMP.
Temporary file directory
This directory is used by
Oasis montaj
to store temporary
files. Depending on the application, the requirements for
storage in this directory can be VERY large (from 10
megabytes to gigabytes). We recommend setting this
parameter to a very FAST drive. This will improve
performance of all large data operations (magmap, gridding,
etc).
Oasis montaj
cannot start if this drive is invalid or if it is set
to a drive in which it cannot create files (CD ROM). Please
ensure that the directory is always valid.
Note that in previous versions of
Oasis montaj
the
GEOTEMP environment variable determined where this
directory was stored. This variable is no longer used and the
setting is controlled through the Windows registry.
