OverrideKeys (page device)

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP

OverrideKeys , a subdictionary of the pagedevice dictionary, provides a mechanism for overriding values passed to setpagedevice for certain page device keys. Every entry has a key corresponding to a pagedevice key, and a Boolean value. If the value is true , calls to setpagedevice will not be allowed to change the value of the key. You cannot add keys to OverrideKeys , only change the value of the flag for those already present.

For example, this code fragment:

            <<
              /OverrideKeys << /HWResolution true >>
              >> setpagedevice

means that a subsequent

<< /HWResolution [999 999] >> setpagedevice

will have no effect.
