$psdoc
) : stringThis function is not implemented yet. It will always return an empty string. The idea for a later implementation is to write the contents of the postscript file into an internal buffer if in memory creation is requested, and retrieve the buffer content with this function. Currently, documents created in memory are send to the browser without buffering.
