By default it outputs the encoded image data directly to standard output. OPTIONS -h, --help Print help and exit. -v, --version Print version and exit. -x, --xdisplay=hostname:number.screen_number Sets the xdisplay to use. -f, --format=STRING Sets the desired output format, by default maim will attempt to determine the desired output format automatically from the out- put file. If that fails it defaults to a lossless png format. Currently only supports `png`, `jpg`, `bmp`, and `webp`. -i, --window=WINDOW By default, maim captures the root window. This parameter over- rides this and sets the desired window to capture. Allows for an integer, hex, or `root` for input. -g, --geometry=GEOMETRY Sets the region to capture, uses local coordinates from the given window. So -g 10x30-5+0 would represent the rectangle wxh+x+y where w=10, h=30, x=-5, and y=0. x and y are the upper left location of this rectangle. -w, --parent=WINDOW By default, maim assumes the --geometry values are in respect to the provided --window (or root if not provided). This parameter overrides this behavior by making the geometry be in respect to whatever window you provide to --parent. Allows for an integer, hex, or `root` for input. -B, --capturebackground By default, when capturing a window, maim will ignore anything beneath the specified window. This parameter overrides this and also captures elements underneath the window. -d, --delay=FLOAT Sets the time in seconds to wait before taking a screenshot. Prints a simple message to show how many seconds are left before a screenshot is taken. See --quiet for muting this message. -u, --hidecursor By default maim super-imposes the cursor onto the image, you can disable that behavior with this flag. -m, --quality An integer from 1 to 10 that determines the compression quality. For lossy formats (jpg and webp), lower settings will produce smaller files with lower quality, while higher settings will in- crease quality at the cost of higher file size. A quality of 10 is lossless for webp. For png, lower settings will compress faster and produce larger files, while higher settings will com- press slower, but produce smaller files. No effect on bmp im- ages. -s, --select Enables an interactive selection mode where you may select the desired region or window before a screenshot is captured. Uses the settings below to determine the visuals and settings of slop. SLOP OPTIONS -b, --bordersize=FLOAT Sets the selection rectangle's thickness. -p, --padding=FLOAT Sets the padding size for the selection, this can be negative. -t, --tolerance=FLOAT How far in pixels the mouse can move after clicking, and still be detected as a normal click instead of a click-and-drag. Set- ting this to 0 will disable window selections. Alternatively setting it to 9999999 would force a window selection. -c, --color=FLOAT,FLOAT,FLOAT,FLOAT Sets the selection rectangle's color. Supports RGB or RGBA in- put. Depending on the system's window manager/OpenGL support, the opacity may be ignored. -r, --shader=STRING This sets the vertex shader, and fragment shader combo to use when drawing the final framebuffer to the screen. This obviously only works when OpenGL is enabled. The shaders are loaded from ~/.config/maim. See https://github.com/naelstrof/slop for more information on how to create your own shaders. -n, --nodecorations=INT Sets the level of aggressiveness when trying to remove window decorations. `0' is off, `1' will try lightly to remove decora- tions, and `2' will recursively descend into the root tree until it gets the deepest available visible child under the mouse. De- faults to `0'. -l, --highlight Instead of outlining a selection, maim will highlight it in- stead. This is particularly useful if the color is set to an opacity lower than 1. -D, --nodrag Allows you to click twice to indicate a selection, rather than click-dragging. -q, --quiet Disable any unnecessary cerr output. Any warnings or info simply won't print. -k, --nokeyboard Disables the ability to cancel selections with the keyboard. -o, --noopengl Disables graphics hardware acceleration. EXAMPLES Screenshot the active window and save it to the clipboard for quick pasting. maim -i $(xdotool getactivewindow) | xclip -selection clipboard -t image/png Save a desktop screenshot with a unique ordered timestamp in the Pic- tures folder. maim ~/Pictures/$(date +%s).png Save screenshot to the Pictures folder and add it to the clipboard at the same time. maim | tee ~/Pictures/$(date +%s).png | xclip -selection clipboard -t image/png Prompt for a region to screenshot. Add a fancy shadow to it, then save it to shadow.png. maim -s | convert - \( +clone -background black -shadow 80x3+5+5 \) +swap -background none -layers merge +repage shadow.png In scripts, here in i3 window manager: enable light on the Thinkpad T430 laptop, wait 5 seconds, screenshot all displays, save file like ~/screenshots/2022-dec-21--12-56-08_maim.png, disable light, show i3 notification for 3 seconds. bindsym $mod+Shift+x exec " echo 1 > /sys/class/leds/platformmicmute/brightness; sleep 5; maim --hidecursor ~/screenshots/$(date +%Y-%b-%d--%H-%M-%S_maim | tr A-Z a-z).png; echo 0 > /sys/class/leds/platformmicmute/brightness; i3-nagbar --message 'Screenshot created' --type warning & sleep 3; pkill i3-nagbar" SEE ALSO slop(1) BUGS No known bugs.
