ps_set_parameter — Sets certain parameters
$psdoc
, string $name
, string $value
) : boolSets several parameters which are used by many functions. Parameters are by definition string values.
psdocResource identifier of the postscript file as returned by ps_new().
nameFor a list of possible names see ps_get_parameter().
valueThe value of the parameter.
成功时返回 TRUE， 或者在失败时返回 FALSE。
Note that when setting a parameter such as "true" or "false", in this case "true" and "false" are strings.
Correct syntax would be:
<?php ps_set_parameter($ps, "linebreak", "true"); ?>
This does NOT work:
<?php ps_set_parameter($ps, "linebreak", true); ?>
