![]() ![]() It works with EWMH/NetWM compatible X Window Managers. The following script takes a screenshot of the currently focused window. Import -window root -crop $x$h+$x+$y head_$i.png Xdpyinfo -ext XINERAMA | sed '/^ head #/!d s///' | As long as Xinerama information is available from the X server, the following will work: ![]() In this case, you may want to take screenshot of each physical screen individually. If the physical screens are different in height, you will find dead space in the screenshot. Xinerama-based multi-head setups have only one virtual screen. $ convert +append /tmp/0.png /tmp/1.png screenshot.png $ import -window root -display :0.1 -screen /tmp/1.png $ import -window root -display :0.0 -screen /tmp/0.png If you run twinview or dualhead, simply take the screenshot twice and use imagemagick to paste them together: Note: If you prefer graphicsmagick alternative, just prepend "gm", e.g. With -pause you can specify a delay in which you can, for example, lower some windows. Running import without the -window option allows selecting a window or an arbitrary region interactively. Is harder to use when the correlation between quality and storage size is not clear.Īn easy way to take a screenshot of your current system is using the import(1) command: $ convert image.jpg -quality 85% image_small.jpg Hopefully, this will shorten the transmission time. $ convert image.jpg -define jpeg:extent=3000KB image_small.jpg To achieve reasonable quality for a given storage size: $ magick frame_red.gif -gravity South -chop 0x10 chop_bottom.gif Which is easier as less numbers, or trial and error, is involved. One can also -chop to cut of a single edge from an image, using gravity to select that edge. Where WIDTH and HEIGHT is the cropped output image size, and X and Y is the offset from the input image size. $ mogrify -crop WIDTHx HEIGHT+ X+ Y -format jpg *.png To crop part of multiple images and convert them to another format: $ convert -append input.pngs output.png Crop, chop The basic usage of this facility is to specify the existing, and desired, image formats as the filename extension. Opposite operations can be performed by using a plus instead of a minus. Number of tiles per row and column (e.g.Note: The sign before an option is important. Name of texture to tile onto the image background Seed a new sequence of pseudo-random numbers Settings remain in effect until parenthesis boundary.

The montage command recognizes these options. To have more control over the layout of your image tiles, use the montage command instead. This is designed to quickly view a collection of images. Magick '*.png' -resize 320x320 -label %f ashlar:ashlar.png You can label the image tiles with, for example, -label %f. Use -define ashlar:best-fit=true to align on both the left and right edges. By default, alignment is along the left edge. You can explicitedly set the canvas size and border width by appending to the filename, e.g. By default, a reasonable canvas size and border width is determined relative to the image collection you provide. Use the Ashlar pseudo-image format to lay out an image sequence in continuous irregular courses. Further discussion is available in More Graphics from the Command Line and Examples of ImageMagick Usage. You can find additional examples of using montage at Examples of ImageMagick Usage and Graphics from the Command Line. Ok, let's add some decorations: magick montage -label %f -frame 5 -background '#336699' -geometry +4+4 rose.jpg red-ball.png frame.jpg To get started, let's montage two images into a single composite: magick montage -background '#336699' -geometry +4+4 rose.jpg red-ball.png montage.jpg We list a few examples of the montage command here to illustrate its usefulness and ease of use. See Command Line Processing for advice on how to structure your montage command or see below for example usages of the command. The images are tiled on the composite image optionally adorned with a border, frame, image name, and more. Use the montage program to create a composite image by combining several separate images. ![]()
