Import -window "$activeWinId" /tmp/$(date +%F_%H%M%S_%N).pngĪlternatively, the following should work regardless of EWMH support: To avoid overwriting previous screenshots, the current date is used as the filename.ĪctiveWinLine=$(xprop -root | grep "_NET_ACTIVE_WINDOW(WINDOW)") It can be used from the command line or as a COM object using PowerBuilder’s OLEObject functionality.
#IMAGEMAGICK CONVERT IMAGE FORMAT SOFTWARE#
It works with EWMH/NetWM compatible X Window Managers. ImageMagick is a free open-source software package that allows you to convert image files between formats, resize images and perform other functions. 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: Montage: juxtapose image thumbnails on an image canvas. Large image support: read, process, or write mega-, giga-, or tera-pixel image sizes. ImageMagick on the iPhone: convert, edit, or compose images on your iOS device such as the iPhone or iPad. In this case, you may want to take screenshot of each physical screen individually. Image identification: describe the format and attributes of an image. 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. Import -window root -display :0.1 -screen /tmp/1.pngĬonvert +append /tmp/0.png /tmp/1.png screenshot.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: Supposing your source image is called “input.jpg,” and you want to create “output.Note: If you prefer graphicsmagick alternative, just prepend "gm", e.g. (These could be in separate directories, but you’ll need to specify relative paths in that case…we’re keeping this example simple for command line novices.) Simply specify your input and output files. with no other arguments, as little processing as possible will be done to move from one format to the other. Using the magick command (or convert for IM 6.x users) you con convert any image format to any other. This won’t actually resize the image to the exact dimensions specified. Here is the list of ImageMagick command-line utilities. To resize an image to specific dimensions, use the convert command with an input file, the -resize parameter, your preferred dimensions, and an output filename: convert original.png -resize 100x100 new.png. Put the image(s) you want to convert and the eink-*.png images in the same directory, then “cd” to that directory. Resize to specific dimensions and keep aspect ratio.
But if you really need it, refer to the ImageMagic documentation for image resizing. ImageMagick does have scale and crop functions, but that’s a whole added layer of complexity…you’ll probably have an easier time using GUI tools, most operating systems have something basic included. The software feels a bit anachronistic because it has no GUIbut to its credit it. We’ll assume your source image(s) are already sized for the e-ink display (check the specific product page for your display’s dimensions, there’s a variety). ImageMagick is a command-line tool for image conversion and processing. BMPs, because that’s what CircuitPython works with…it’s a relatively easy image format for microcontrollers to handle. An example image is available to help you get familiar with Magick Online Studio, version 7.1.0. Next, set any of the optional parameters below. It can read and write images in a variety of formats (over 200). To convert, edit, or compose your image online, press Choose File to browse and select your image file or enter the URL of your image. We’ll ask ImageMagic to output everything as. ImageMagick is a software suite to create, edit, compose, or convert bitmap images.
