(v13) The getPDFtrailer operator

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP.

int getPDFtrailer dict

This operator is defined in internaldict.

The supplied int is a PDF execution context ID, as returned by pdfopen. The returned dict is a copy of the trailer dictionary, held in PostScript VM. (The trailer dictionary provides access to the hierarchy of the PDF file.)

A new object type, called pdfobjtype, is present in the trailer dictionary entries. A pdfobjtype represents the PDF indirect reference construct (for example, “10 0 R” ). All you can do with pdfobjtype in PostScript code is use cvs and related operations ( = , == , and so on) or pass them to getPDFobject.

It is useful to note that the internal structure of pdfobjtype means that these simple literal objects are perfectly valid keys for dictionaries.
