Here are just a few examples of what ImageMagick can do for you:Ĭreate a GIF animation sequence from a group of images. We continue to maintain the legacy release of ImageMagick, version 6, at. The authoritative source code repository is. The authoritative ImageMagick web site is. It runs on Linux, Windows, Mac Os X, iOS, Android OS, and others. The current release is ImageMagick 7.1.0-49. ImageMagick utilizes multiple computational threads to increase performance and can read, process, or write mega-, giga-, or tera-pixel image sizes. It is distributed under a derived Apache 2.0 license. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. ![]() ImageMagick can 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 images in a variety of formats (over 200) including PNG, JPEG, GIF, WebP, HEIC, SVG, PDF, DPX, EXR and TIFF. ![]() This all doesn't work (they all produce all-red images):Ĭonvert src.pnm \( alpha.pnm -colorspace gray -alpha off \) -compose copy-opacity -composite -background red -flatten out.pnmĬonvert src.pnm \( alpha.pnm -colorspace gray -alpha off \) -compose copy-opacity -background red -flatten out.pnmĬonvert -background red src.pnm \( alpha.pnm -colorspace gray -alpha off \) -compose copy-opacity -flatten out.Use ImageMagick ® to create, edit, compose, or convert digital images. However, I want to directly write a PNM (no alpha). What works is if I run two convert commands (one writes a PNG, the other flattens). However, I also want to flatten the image afterwards with a background color and I cannot get that to work for the life of me. That works fine:Ĭonvert src.pnm \( alpha.pnm -colorspace gray -alpha off \) -compose copy-opacity -composite out.png What I'm trying to do is compose two images, one with pixel data and the other with an alpha channel data (grayscale image) together.
