Hi hiro
Since I don't know why that one second sleep command was put in there, I didn't remove it. I though it might have
been to allow you time to move the mouse pointer somewhere out of the way, but from what I've seen, the mouse
pointer is not captured.

I guess in the original version it was meant for you to have some time to arrange things, like bringing the right window to the front or hiding what you invoked screenshot.sh from, but with this addition it shouldn't be needed I think.

Once xwininfo is invoked pointer device can't be used to arrange anything, while there is unlimited time to use keyboard before selecting window.

Hi tinypoodle
That may be, but the sleep command is after xwininfo has finished executing, leaving you one second before
imlib2_grab runs.

Ah yes, correct!
And it seems that if switching desktop within that 1 sec and the selected window does not exist in desktop chosen at time of execution imlib2_grab, then there is a popup but no screenshot saved...

Hi tinypoodle
Switching the desktop probably changes the root window. In order to capture the window you clicked on, imlib2.grab
needs to know its position, size, etc. I believe that involves making a series of calls to X starting with the root windows
ID to find all the child window IDs until a match is found. If the window you clicked on does not exist on that desktop,
it won't be found and nothing is captured. Even if it could be found, you would get a black (or gray) image since the
image imlib2.grab creates is of what is visible on the screen.

I've been using a similar script, though mine pipes xwd through a couple netpbm tools.
The only barriers that can stop you are the ones you create yourself.

Hi beroje
Yes, that was copied verbatim from the original screenshot.sh. Maybe it would be better to omit the path altogether.

This script cannot find imlib2_grab.

Dear Juanito:
Both imlib2-bin.tcz & xorg-7.7-bin.tcz were loaded.

Everything appears ok until attempting to find the .png in the home directory.  The file never got written to disk!

Sincerely,
eltone

Hi eltone
Did you read replies #22 and 23? Try changing:
Code: [Select]
/bin/sh -c "/usr/bin/imlib2_grab -id $WINDOW_ID $HOME/$filename"to:
Code: [Select]
/bin/sh -c "imlib2_grab -id $WINDOW_ID $HOME/$filename"in the script.
