Variables
A number of environment variables affect the operation of PostShop (and the
applications that may use PostShop). These are normally either unnecessary or
set automatically during installation, but you may want to change their default
values if you are customizing your system. If you would like to check on their
settings, you can inspect the wrapper script(s) in $VV_HOME/bin. An
explanation of each environment variable follows:
VV_HOME is the location where ScanShop is installed. By default,
/opt/Vividata on Solaris 2.x, and /usr/vividata on all other systems. It is
set by default when the program is executed and need only be changed
if there is some specific reason for doing so.
LM_LICENSE_FILE tells Vividata products where to look for the
FLEXlm license file. For further information, please see the section
“LM_LICENSE_FILE environment variable” on page 146.
VVP_FILTER provides a way for ScanShop to read file formats
through a filter the user provides, thus extending the built-in set of file
formats that are recognized. If a file fails to read through a built-in file
reader, then the input is passed through the designated external filter to
be converted to a recognized format. The value set should be the path to
an external filter and any command-line options it requires. The filter
must take stdin and output the results via stdout. The default filter is the
mpage utility, which converts ASCII text to PostScript. Refer to any
available references or help files for information regarding the usage of
mpage and other common filters.
VV_JPEG_QUALITY affects JPEG file writing, ranging from 0 to
100. Values from 5 to 95 are generally the most useful; 100 is the best
quality. Default is 75.
VV_JPEG_SMOOTHING affects JPEG file writing, ranging from 0 to
100. 0 is none; 100 is the most. Default is 0.
VV_MWM may be needed to make ScanShop interact with certain
window managers properly. If images appear black or the colormap
appears incorrect, try setting VV_MWM to 1. Otherwise, do not set this
variable
