For those who use X server and compiz window manager there is a glitch that prevents proper drawing of rectangle ( rubberbanding ) on the screen while dragging the mouse ( moving mouse with left button pressed).
I conconcted it from the info I found on the net and QT documentation. It works with maim https://github.com/naelstrof/maim screenshot tool. It's based on QT4.
To build it on Ubuntu you need to have QT4 installed. First clone this repository:
git clone https://github.com/trappedinspacetime/qrubberband.git
cd qrubberband
If you also have QT5, you can switch to QT4 via environment variable:
export QT_SELECT=4
then check version of the qmake if it switched to 4.x:
qmake -v
if it's OK:
qmake -project
qmake -makefile
make
run it like
./qrubberband
and drag the screen area, it will print the result in the following formatwxh+x+y, x and y are the starting coordinates.
You can copy it to /usr/local/bin/ via:
sudo cp qrubberband /usr/local/bin/
And you can run it with maim like:
maim -g $(qrubberband) test.png
I use it to translate text with tesseract-ocr. Here is my oneliner bash command:
text=$(maim -g $(qrubberband) | tesseract stdin stdout -l eng | head -c -1 ) ; notify-send --icon=info "$text" "$(wget -U "Mozilla/5.0" -qO - "http://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=tr&dt=t&q=$(echo $text | sed "s/[\"'<>]//g")" | sed "s/,,,0]],,.*//g" | awk -F'"' '{print $2, $6}')" ; echo "$text" ;
It translates English text into Turkish via google translate online tool, you can replace tr with your native language short code.
