The setting format for Parameters to be read by dviout is given by "Option -> All parameters".
Generally, a specification has a form of <parameter>=<setting>, and more than one specifications must be delimited by spaces or new lines. A - may be added before <parameter>. Also, instead of =, : can be used. Dviout interprets the specifications in the order of them. If the same parameters are set, they are overwritten.
There are four kinds of parameter format:
1. Parameters specifying integers such as -dpi: and -br:
2. Parameters specifying lengths such as -LM: and -OX:
3. Parameters specifying strings such as -TEXPK:, -gsx: and -Set:
4. Parameters specifying ON or OFF such as -gbox: and -varf:
For details, see the parameter list or use the ? button on each property sheet to get information of each parameter.
Note: Sometimes parameters specifying integers are set by selecting buttons assigned meanings and not by numbers on the property sheet.
If an integer is specified, in addition to decimal numbers, octal and hexadecimal numbers can be used. For example, when lengths are specified as in
dpi=300
ttf=1000
br=0x64000
the units of mm, cm, in (inch, 1 inch = 25.4 mm), pt (point, 1 in = 72.27 pt), bp (1 in = 72 bp) and dot/<number>dpi. For example, when the string
LM=4.56mm
RM=54dot/300dpi
is set, if special characters such as spaces or new lines are included, the string is enclosed by single quotes (') or double quotes (") (however, the string may not contain single quotes or double quotes). The ^$ string represents the null string.
When the parameter represents ON or OFF, on is specified by "+" and off by "-". If the settings are not specified, ON and OFF are reversed (toggle switch).
The line starting with "#" or ";" is a comment line (cf. Choose Parameters).
