ImageMagick supports a variety of image types, including JPG photos and PNG graphics. - -### Resizing images - -I often use ImageMagick on my webserver to resize images. For example, let's say I want to include a photo of my cats on my personal website. The photo from my phone is very large, about 4000x3000 pixels, at 3.3MB. That's much too large for a web page. I use the ImageMagick convert tool to change the size of my photo so that I can include it on my web page. ImageMagick is a full suite of tools, one of the most common is the `convert` command. - -The ImageMagick `convert` command uses this general syntax: - - -``` -`convert {input} {actions} {output}` -``` - -To resize a photo called `PXL_20210413_015045733.jpg` to a more manageable 500-pixel width, type this: - - -``` -`$ convert PXL_20210413_015045733.jpg -resize 500x sleeping-cats.jpg` -``` - -The new image is now only 65KB in size.  - -![Sleeping cats][2] - -Jim Hall, [CC BY-SA 4.0][3] - -You can provide both width and height dimensions with the `-resize` option. But, by providing only the width, ImageMagic does the math for you and automatically retains the aspect ratio by resizing the output image with a proportional height. - -### Install ImageMagick on Linux - -On Linux, you can install ImageMagick using your package manager. For instance, on Fedora or similar: - - -``` -`$ sudo dnf install imagemagick` -``` - -On Debian and similar: - - -``` -`$ sudo apt install imagemagick` -``` - -On macOS, use [MacPorts][4] or [Homebrew][5]. - -On Windows, use [Chocolatey][6]. - --------------------------------------------------------------------------------- - -via: https://opensource.com/article/21/9/resize-image-linux - -作者：[Jim Hall][a] -选题：[lujun9972][b] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]: https://opensource.com/users/jim-hall -[b]: https://github.com/lujun9972 -[1]: https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/osdc-photo-camera-blue.png?itok=AsIMZ9ga (Old camera blue) -[2]: https://opensource.com/sites/default/files/sleeping-cats.jpg (Sleeping cats) -[3]: https://creativecommons.org/licenses/by-sa/4.0/ -[4]: https://opensource.com/article/20/11/macports -[5]: https://opensource.com/article/20/6/homebrew-mac -[6]: https://opensource.com/article/20/3/chocolatey diff --git a/translated/tech/20210906 Resize an image from the Linux terminal.md b/translated/tech/20210906 Resize an image from the Linux terminal.md new file mode 100644 index 0000000000..9672eda344 --- /dev/null +++ b/translated/tech/20210906 Resize an image from the Linux terminal.md @@ -0,0 +1,81 @@ +[#]: subject: "Resize an image from the Linux terminal" +[#]: via: "https://opensource.com/article/21/9/resize-image-linux" +[#]: author: "Jim Hall https://opensource.com/users/jim-hall" +[#]: collector: "lujun9972" +[#]: translator: "geekpi" +[#]: reviewer: " " +[#]: publisher: " " +[#]: url: " " + +从 Linux 终端调整图像的大小 +====== +用 ImageMagick 的转换命令从你的终端收缩一张图像。 +![Old camera blue][1] + +ImageMagick 是一个方便的多用途命令行工具，它能满足你所有的图像需求。ImageMagick 支持各种图像类型，包括 JPG 照片和 PNG 图形。 + +### 调整图像大小 + +我经常在我的网络服务器上使用 ImageMagick 来调整图像大小。例如，假设我想在我的个人网站上发一张我的猫的照片。我手机里的照片非常大，大约 4000x3000 像素，有 3.3MB。这对一个网页来说太大了。我使用 ImageMagick 转换工具来改变照片的大小，这样我就可以把它放在我的网页上。ImageMagick 是一套完整的工具，其中最常用的是 `convert` 命令。 + +ImageMagick 的 `convert` 命令使用这样的一般语法： + + +``` +`convert {input} {actions} {output}` +``` + +要将一张名为 `PXL_20210413_015045733.jpg` 的照片调整到一个更容易管理的 500 像素宽度，请输入: + + +``` +`$ convert PXL_20210413_015045733.jpg -resize 500x sleeping-cats.jpg` +``` + +现在新图片的大小只有 65KB。 + +![Sleeping cats][2] + +Jim Hall，[CC BY-SA 4.0][3] + +你可以用 `-resize` 选项同时提供宽度和高度尺寸。但是，如果只提供宽度，ImageMagic 就会为你做计算，并通过调整输出图像的高度比例来自动保留长宽比。 + +### 在 Linux 上安装 ImageMagick + +在 Linux 上，你可以使用你的包管理器安装 ImageMagick。例如，在 Fedora 或类似系统上： + + +``` +`$ sudo dnf install imagemagick` +``` + +在 Debian 和类似系统上： + + +``` +`$ sudo apt install imagemagick` +``` + +在 macOS 上，使用 [MacPorts][4] 或 [Homebrew][5]。 + +在 Windows 上，使用 [Chocolatey][6]。 + +-------------------------------------------------------------------------------- + +via: https://opensource.com/article/21/9/resize-image-linux + +作者：[Jim Hall][a] +选题：[lujun9972][b] +译者：[geekpi](https://github.com/geekpi) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://opensource.com/users/jim-hall +[b]: https://github.com/lujun9972 +[1]: https://opensource.com/sites/default/files/styles/image-full-size/public/lead-images/osdc-photo-camera-blue.png?itok=AsIMZ9ga (Old camera blue) +[2]: https://opensource.com/sites/default/files/sleeping-cats.jpg (Sleeping cats) +[3]: https://creativecommons.org/licenses/by-sa/4.0/ +[4]: https://opensource.com/article/20/11/macports +[5]: https://opensource.com/article/20/6/homebrew-mac +[6]: https://opensource.com/article/20/3/chocolatey
