![]() ImageMagick is not the only image optimization library in PHP application. ![]() You can use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. It can read and write over 200 image formats, including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. ImageMagick is a free and open-source software that was created in 1987 by John Cristy to create, edit, compose, or convert bitmap images. In this post, we will discuss about how to install ImageMagick PHP Extension (Imagick) for your PHP web application. RunCloud does support the ImageMagick PHP extension, but it is not enabled by default. And since many watermarking software apps cost a good chunk of change, it's important that people know you can watermark for free using awesome utilities like ImageMagick and ffmpeg.When building your website, some PHP web applications including WordPress and Laravel may require the additional ImageMagick PHP extension for advanced image processing. Watermarking is an important part of intellectual property on the web (as long as it's not cropped out or defaced) you can't blame a content creator for wanting to ensure their work is sourced. Your browser does not support the video element.Īs mentioned above, Kevin's post is top class - be sure to read it if you're looking for more detailed options and examples. ffmpeg -i wtf.mpg -i watermark.png -filter_complex "overlay=10:10" wtf-watermarked.mpg It impossible to write a better post than Kevin Sloan's Watermarking Videos from the Command Line with FFMPEG Filters, so I'll simply cite his post: Videos require another utility for watermarking: ffmpeg. To treat an animated GIF, we'll use the convert utility to kick off the process but still use composite to layer the GIF and watermark. Watermarking an animated GIF will take a differnet ImageMagick tactic:Ĭonvert wtf.gif -coalesce -gravity southeast -geometry +10+10 null: watermark.png -layers composite -layers optimize wtf-watermarked.gif This shell script was found at Watermark an Animated GIFĪnimated GIFs are another beast: if you try to watermark them with the ImageMagick method used for a static image, you'll simply get the result of the first frame. If you're looking to watermark an entire directory of images, you can use this helpful shell script: The last three arguments represent the watermark, the source image, and the merged output image name. -dissolve represents the opacity level of the watermark.geometry represents x and y padding offsets from the gravity position. ![]() -gravity represents the direction within the image where the watermark should appear.We'll use the composite utility instead of ImageMagick's popular convert.It will be easiest to show you the command and then explain it, so here we go:Ĭomposite -gravity southeast -geometry +10+10 -dissolve 75% watermark.png ringo.jpg ringo-watermarked.jpg ![]() The best way to watermark an image from command line is ImageMagick. Let me show you how you can watermark basic images, animated GIFs, and videos! Watermark an Image One (weak) way to intellectually protect your work is by watermarking art, from imagery to video and more. I'm lucky enough that my blog is mostly recreational but many people rely on their work for a living, especially photographers and graphic artists. I don't consider this blog art but I'm annoyed as hell when I see my blog posts show up on another site. As a content creator I respect an author or artist's desire to protect their work.
