(v13) FontBitmap callback
This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.
A procedure may be supplied to be called whenever a Type 3 font including an image or imagemask is encountered. Such a callback normally implies that a bitmapped screen font has been included in the job.
The procedure is called with two items on the operand stack: the font name and its UniqueID. Either or both of these items may be null if they were not included within the font itself.
