Geometry of a rectangular screen region

python-xrectsel

Geometry of a rectangular screen region

The project idea based on xrectsel. Its Python variant with some enhancements.

Installation:

pip install python-xrectsel

Usage:

❯ xrectsel --help
Usage: xrectsel [OPTIONS]

Options:
  -f, --format TEXT               Format output string with fallowing options:

                                  %x - start x-coordinate

                                  %y - start y-coordinate

                                  %X - start

                                  %Y - end

                                  %w - width

                                  %h - height

                                  Note: default output is in "%wx%h+%x+%y"
                                  format.

  -ci, --cursor-icon [crosshair|cross|pencil|dotbox]
                                  Select cursor icon
  -cf, --cursor-foreground <INTEGER INTEGER INTEGER>...
                                  Select cursor foreground color
  -cb, --cursor-background <INTEGER INTEGER INTEGER>...
                                  Select cursor background color
  -h, --help                      Show this message and exit.

• We can collect selected region geometry just by command xrectsel. Default format is %wx%h+%x+%y

$ xrectsel
$ # select rectangle on sreen
901x634+44+7 #(x-coordinate, y-coordinate, width, height)

• We can format output geometry string

$ xrectsel -f "--x=%x --y=%y --width=%w --height=%h"
--x=264 --y=387 --width=1204 --height=519

python-xrectsel's Issues

Cannot select entire screen

Summary

When I try to select the entire screen, the result is 1 pixel off in both dimensions.
This looks like a bug in xclip because when I select entire screen using maim screenshotting tool, resulting image has correct dimensions.

Excpected result

2560x1440+0+0 (2k screen)

Actual result

2559x1439+0+0

Key error in dragging

No matter how I call the program, it always just errors for me.
