if imagemagick is installed you can use "import"

| Some environments will take a screen shot with 'print screen' button. And 'shift+print screen' will let you draw a rectangle with the mouse to select the part of the screen to take. Not sure what window manager/desktop software is in use for that, but it's worth a try. |

use import from imagemagick
I have it bound to the print screen key but I run openbox.
anyway from the man page
| Code: | NAME
import - saves any visible window on an X server and outputs it as an image file. You can capture a single
window, the entire screen, or any rectangular portion of the screen. The window to capture is selected by
clicking the desired window or a program option.
SYNOPSIS
import [options] output-file |

If you use Gnome, it has a Screenshot thingy (from search, type s c r ...) that lets you take a screenshot, either:
a) Grab the whole screen
b) Grab the current window
c) Select area to grab
Another option,
If you are familiar with Gimp ... File->Create -> Screenshot

If you're using KDE you could install kde-apps/spectacle and use keyboard shortcuts ('System Settings' > 'Workspace' > 'Shortcuts' > 'Custom Shortcuts'):
| Quote: | Screenshots
|- Start Screenshot Tool PrtScr
|- Take Full Screen Screenshot Shift+PrtScr
|- Take Active Window Screenshot Meta+PrtScr |
Have you tried one of the various other screen capture applications, such as Scrot? You could also set up a shortcut to the PrtScr key to capture a full screen, to Alt+PrtScr to capture the active window, and so on using Scrot:
| Code: | SYNOPSIS
scrot [options] [file]
DESCRIPTION
scrot is a screen capture utility using the imlib2 library to acquire and save images. scrot has a few options,
detailed below. Specify [file] as the filename to save the screenshot to. If [file] is not specified, a date-
stamped file will be dropped in the current directory.
OPTIONS
-h, --help
display help output and exit.
-v, --version
output version information and exit.
-b, --border
When selecting a window, grab wm border too
-c, --count
Display a countdown when used with delay.
-d, --delay NUM
Wait NUM seconds before taking a shot.
-e, --exec APP
Exec APP on the saved image.
-q, --quality NUM
Image quality (1-100) high value means high size, low compression. Default: 75. (Effect differs depending on
file format chosen).
-m, --multidisp
For multiple heads, grab shot from each and join them together.
-s, --select
Interactively select a window or rectangle with the mouse.
-u, --focused
Use the currently focused window.
-t, --thumb NUM
generate thumbnail too. NUM is the percentage of the original size for the thumbnail to be.
-z, --silent
prevent beeping.
SPECIAL STRINGS
Both the --exec and filename parameters can take format specifiers that are expanded by scrot when encountered.
There are two types of format specifier. Characters preceded by a '%' are interpreted by strftime(2). See man strf‐
time for examples. These options may be used to refer to the current date and time. The second kind are internal
to scrot and are prefixed by '$' The following specifiers are recognised:
$f image path/filename (ignored when used in the filename)
$n image name (ignored when used in the filename)
$s image size (bytes) (ignored when used in the filename)
$p image pixel size
$w image width
$h image height
$t image format
$$ prints a literal '$'
\n prints a newline (ignored when used in the filename)
EXAMPLE
scrot '%Y-%m-%d_$wx$h.png' -e 'mv $f ~/shots/'
This would create a file called something like 2000-10-30_2560x1024.png and move it to your shots directory. |
There are various other screen-capture utilities. For example you could use x11-apps/xwd and media-gfx/imagemagick in a Bash script launched by a keyboard shortcut for PrtScr (albeit more complicated than Anon-E-moose's imagemagick import approach):
| Code: | #!/bin/bash
DISPLAY=:0 xwd -root > /tmp/screenshot.xwd
convert /tmp/screenshot.xwd /home/fitzcarraldo/screenshot.png |
Or you could use media-libs/netpbm instead of imagemagick:
| Code: | #!/bin/bash
DISPLAY=:0 xwd -root | xwdtopnm | pnmtopng > /home/fitzcarraldo/screenshot.png |

Fitzcarraldo ... probably best not to hardcode things that may be variable:
| Code: | #!/bin/sh
set -e
xpid="$(pgrep -n X)"
display="$(egrep -aoz ':[0-9](.[0-9])?' /proc/$xpid/cmdline)"
dat="$(date +'%d-%m-%Y-%H%M%S')"
DISPLAY="$display" xwd -root > ${TMPDIR:-/tmp}/screenshot-${dat}.xwd
convert ${TMPDIR:-/tmp}/screenshot-${dat}.xwd $HOME/screenshot-${dat}.png |
best ... khay |

The only reason I mentioned import is I already had imagemagick because other packages used/needed it.
I used to use screengrab and if all you need is just the screen grabber then it or one of the others would work fine.
In other words there are several ways to get images of your desktop or portions of it.

Thanks everyone!
Every time I have a question here, I am moved by the passion in this forum.
I may try imagemagick first.
Thanks again.

I put this into my .bashrc:
| Code: | function shot()
{
import -frame -strip -quality 75 "$HOME/$(date +%s).png"
}
|
You must have Imagemagick Installed.
Type in terminal 'shot' then you have a Screenshot
[Moderator edit: added [code] tags to preserve output layout - although in this case, there appears to be no layout to preserve. -Hu] |

| I have a special directory for screen shots, $HOME collects all kinds of crap from everywhere. ~/Pictures/Screenshots in my case. |
