We have found icut, ipaste, and pprint to be very useful for dumping and
restoring images so that they can be composed for a photograph of the screen
(icut, ipaste) or for sending an image to a postscript laser printer (pprint).
To use icut on a 4D/70, one must go through the following steps:
i) get an image on the screen
ii) type "icut some_image_filename"
At this point, an empty red rectangle appears at the arrow cursor. Click a
mouse button to turn it into a window which will be called "icut".
iii) put the arrow cursor inside the window and press and hold the "Alt" key
iv) keeping the key down, move the cursor to the lower left hand corner of
the image you wish to cut
v) press and hold down the left mouse button
vi) move the arrow cursor to the upper right hand corner of the image
vii) simultaneously, release the Alt key and the left mouse button
I have not tried to do full screen images, but 800x800 does not take
more than 10 or 20 seconds to dump. When the icut window disappears, the
dump is complete.
To restore your image, type "ipaste some_image_filename".
To create a postscript file, invoke the command
"pprint some_image_filename > some_othe_image_filename"
The pprint command lives in /usr/lib/print in our O.S. (version 3.1 C).
The file which is created is a postscript file and fully portable - we
FTP ours to a Vax running VMS and send it to a laser printer from there.
It seems to do grey shades of at least 8 colors; does a consultant out there
know how many it is capable of doing?
