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.

colour(c)

Not yet implemented.

width(w)

Not yet implemented.

line(l)

Not yet implemented.

marker(m)

Not yet implemented.

msize(ms)

Not yet implemented.

font(f)

Not yet implemented.

notext

Not yet implemented.

overlay

Not yet implemented.

update

Not yet implemented.

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.
