Informations about the HardCopy module:
The procedure
DumpRPort
, which you can also use in your own programs
easily, it possible to dump a specified RastPort to the printer rather
simply. The procedure is very flexible, but it communicates with the
printer device for you (this is not difficult, but complicated). For the
parameters are described in german in the
HardCopy.def
module they will be
explained below for the non german users:
parameter(s) : Description
-----------------+-----------------------------------------------------------
rp : pointer to RastPort to be dumped
cm : pointer to colormap to be used (can be a custom one)
vm : type of the RastPort's ViewPort
x0,y0,w,h : this sector of the rastport shall be dumped
prtw,prth : size of the dump (see below!)
s : special flags, define what prtw,prth mean (see below!!)
err : exact error specification
DumpRPort
returns TRUE if everything is okay, FALSE if anything went wrong.
If FALSE is returned, err tells the exact error.
The
special flags
define how prtw,prth are interpreted:
Flags : Meaning of prtw and prth
------------------------+----------------------------------------------------
none : absolute size in printer pixels
milCols,milRows : size in 1/1000 inch
fullCols,fullRows : none; Dump is made as large as possible
fracCols,fracRows : fraction of maximum size
center : none; dump will be centered
aspect : dump will be undistorted
density1,2,4 : none; change printer density
For complete definition see the ROM Kernel Reference Manuals!
I hope you can use it! -Rob-
