Purpose
Redraw or store a picture
Parameters
device
-
Graphic device to which the picture is sent.
read(dsn)
-
Not yet implemented.
user(u)
-
Not yet implemented
size(s)
-
Size (width and height) of the plot
area, given by two numbers interpreted as millimeters
or by a DIN format specification.
Default is the global plot size specified by command
DATTR
;
if only width or height are given, the missing
parameter is calculated using the ratio of the global
size.
The picture is mapped onto the plot area according to
the scaling mode (fixed or distorted) defined by command
DATTR
.
palette(p)
-
Defines the colour palette for the output picture.
- p=
'MULTI'
for full colours (default)
- p=
'MONO'
for monochrome copies of coloured pictures
colour(c)

width(w)
-

notext

overlay
-

update
-

dummy
-
Not yet implemented.
copies(n)
-
Number of
copies of the picture.
on
-
Writing a picture to the copy plot file (and thus the
possibility to redraw it) is enabled.
This mode
is default when starting a SATAN session.
off
-
Stop writing a picture to the copy plot file.
debug
-
Debug switch. Lots of output !
Function
To provide redrawing, the current picture including all
additions is written to a temporary copy plot file.
This feature must once be enabled by the keyword
on
;
it may be disabled by the keyword
off
in order to
save computing time or to skip parts of a picture.
Executing the command, the copy plot file or the specified data set is read; the input is optionally modified
and sent to the current or new device. With the keyword
update
the modified picture is rewritten to the copy
plot file.
Remarks
The keywords
colour
,
width
,
line
,
marker
,
msize
and
font
,
provide an easy facility to change graphic attributes of the current picture.
See command
DATTR
for the
valid system indices which may be used to define attributes look-up tables. The system index 0 for colour
(background) or line type (invisible) can especially be used to exclude parts of the picture.
If any of the keywords is omitted, or if a list contains succeeding commas or less than 10 elements, the
respective original attributes are effective.
Note: Width, marker size, and dash and gap length of
lines, are absolute quantities; they are
not transformed according to the actual plot size.
Examples
DCOPY / ON
...
DCOPY p65gps / copies(2) palette(mono)
Two copies of
the actual picture are sent to the printer p65gps
in monochrome mode, that is without the colours being coded as greyscales.
