Methods to do screen captures from various platforms.
If you are accessing bioinf through any X-windows graphics interface, then
the program xview
program running on bioinf can capture any image displayed in the X-window.
You bioinf account should be also set up with GIMP, which has capabilities
comparable to Photoshop. To acquire an image with GIMP:
-
If you are using Xwin32, you will need to configure the window tab to "multiple"
windows, or export a desktop and open the terminal window from within it.
-
Get the graphic you want displayed in your X-window.
-
Activate GIMP
-
If you are working out of an exported desktop, there should be a GIMP icon
on it to activate the program, otherwise open another terminal window from
the desktop and type gimp.
-
If you have only exported the display of the graphics program and not a
desktop, then open a second ssh session into bioinf, export that to your
IP, and type gimp.
-
In the little GIMP selection panel that pops up, <file><acquire><screenshot><window
with decoration><OK>
-
Wait for cursor to become a cross hair, then click the window you want
to capture.
-
Wait for the captured window to be displayed
-
To crop, select the rectangular selection tool in the GIMP selection panel,
select the rectangle you wish to retain, and then do <edit><copy>
or <control X> to copy it to the X windows clipboard. Then open
another palate with <file><new> and <edit> <paste> or <control
V>.
-
To save, use <file> <save as>, and specify the format for saving
with the extension. .gif or .jpeg are safest, with .gif files being
smaller but possibly introducing some color distortion. These files
can be copied by scp to your local system and incorporated into powerpoint
or html documents.
The SGI in Dr. Demeler's office (dedicated to Insight II) will also have
a GIMP icon on its desktop. Because of the way this machine shares
your directories with bioinf, there may be two GIMP icons, one of which
does not work. The one that does work may be distinguished by a name
like GIMP_SGI. You can also start GIMP from this SGI by opening a
terminal window and typing gimp. [As of this writing GIMP
is not yet installed on this machine, but it should be there by the time
you need it. Ask Dr. Demeler if you have difficulties finding the
program.]
If your interface is running under another operating system, such as
Microsoft Windows or Mac Os, then there may also be an option to use a
screen capture utility running locally.
-
For Windows PC's you can capture an image of the active window to the clipboard
by <alt printscreen>, or of the whole screen by <printscreen>. (<printscreen>
refers to a special function key on the keyboard). These images can
be pasted into powerpoint or netscape composer. For cropping they
can be pasted into MS_Paint and then a subsection selected and copied to
the clipboard.
-
A commercial utility for Windows named PixWizard
can be purchased for $30 or tried out for 30 days.
-
Mac Os 9 has a built in utility activated by cmd-shift-4.
-
Mac Os X there is a screen capture utility built in named Picturegrabber.
Access it by <click on background><go to applications folder><utilities>
If you are using LaserGene or Oligo6.0 from a PC, then you will need to
do Windows screen capture as described above..
If you are using the site-licensed Vector
NTI, it has a built in utility named "camera". But it only works
on items within the Vector NTI windows.
If you are using an SGI in the structure center cluster, there is a
utility called snapshot
that can be used. The format saved will be .rgb. The SGI in
Dr. Demeler's office (dedicated to Insight II) also has snapshot.
As of this writing the convert utility that is needed together with snapshot
is not yet installed there, but it should be there soon.
