man maim (1): Takes screenshots

SYNOPSIS

maim [options] [file]

DESCRIPTION

maim (MAke IMage) is a utility that takes screenshots of your desktop using imlib2. It's meant to overcome shortcomings of scrot and performs better than scrot in several ways.

OPTIONS

--help: Print help and exit
-V, --version: Print version and exit

Options

--xdisplay=hostname:number.screen_number: Sets the x display.
-s, --select: Enables user region selection. Requires slop to be installed. (default=off)
-x, --x=INT: Sets the x coordinate for taking an image
-y, --y=INT: Sets the y coordinate for taking an image
-w, --w=INT: Sets the width for taking an image
-h, --h=INT: Sets the height for taking an image
-g, --geometry=WxH+X+Y: Set the region to capture
-d, --delay=FLOAT: Set the amount of time to wait before taking an image. (default=`0.0')
-i, --windowid=INT: Set the window to capture. Defaults to the root window id.
--localize: Localizes given geometry to the given window. So maim -i $ID -g 100x100+0+0 --localize would screenshot the top-left 100x100 pixels of the given window, rather than the top-left 100x100 pixels of the root window. (default=off)
--hidecursor: Prevents the system cursor from showing up in screenshots. (default=off)
-m, --mask=STRING: Masks off-screen pixels so they don't show up in screenshots. (possible values="auto", "off", "on" default=`auto')

SLOP OPTIONS

--nokeyboard: Disables the ability to cancel selections with the keyboard. (default=off)
-b, --bordersize=INT: Set the selection rectangle's thickness. Does nothing when --highlight is enabled. (default=`5')
-p, --padding=INT: Set the padding size of the selection. Can be negative. (default=`0')
-t, --tolerance=INT: How far in pixels the mouse can move after clicking and still be detected as a normal click instead of a click and drag. Setting this to 0 will disable window selections. (default=`2')
--gracetime=FLOAT: Set the amount of time before slop will check for keyboard cancellations in seconds. (default=`0.4')
-c, --color=FLOAT,FLOAT,FLOAT,FLOAT: Set the selection rectangle's color. Supports RGB or RGBA values. (default=`0.5,0.5,0.5,1')
-n, --nodecorations: Attempt to select child windows in order to avoid window decorations. (default=off)
--min=INT: Set the minimum output of width or height values. This is useful to avoid outputting 0. Setting min and max to the same value disables drag selections. (default=`0')
--max=INT: Set the maximum output of width or height values. Setting min and max to the same value disables drag selections. (default=`0')
-l, --highlight: Instead of outlining selections, slop highlights it. This is only useful when --color is set to a transparent color. (default=off)

EXAMPLES

Screenshot the active window

$ maim -i $(xdotool getactivewindow)

Prompt a transparent red selection to screenshot.

$ maim -s -c 1,0,0,0.6

Save a dated screenshot.

$ maim ~/$(date +%F-%T).png
