| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: printer
Takes a printer stream and returns a number indicating the scaling
factor that the end user has selected on the print job dialog that was
invoked when the printer stream was opened. This number indicates the
scaling that the printer driver itself will perform, and so the
application does not need to do the scaling itself. This scaling
factor is independent of scaling that can be achieved in common
graphics by call (setf stream-units-per-inch)
(see
stream-units-per-inch) on the
printer stream.
If the print job dialog for the particular printer does not support scaling, the return value may be 0 but this has not been tested with many printers.
scale is a
property of the printer
class.
This function is not setf'able. You must specify a value for this property when a printer stream is created with open-stream using the :scale initarg, but some printers may ignore this value.
