填写某政府表格时候，需要把多个图片合并为一张图片。 用Photoshop应该很好解决，但是本地没有安装。于是网上查了一下用imageMagick也可以解决。 meat Appending images vertically in ImageMagick 1 2 3 4 5 # vertical stacking (top to bottom): convert -append 1.jpeg 2.jpeg 3.jpeg out.jpg # horizontal stacking (left to right): convert +append 1.jpg 2.jpg out.jpg ps 另外这篇循环播放gif图片也用到了imageMagick。
install 首先使用macport安装 imagemagick软件包，因为macport是编译安装软件包，所以安装过程会比较久（~9min）。 更加习惯homebrew的可以参考 官网imagemagick download 安装。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 ❯ sudo port install imagemagick Password: ---> Computing dependencies for ImageMagickWarning: cltversion: The Command Line Tools are installed, but MacPorts cannot determine the version.
