Rounded corners on images using PHP?
提问by Dineshaws
Does anyone know how to make a image have rounded corners using a PHP script?
有谁知道如何使用 PHP 脚本使图像具有圆角？

This script shows how to apply rounded corners to images using PHP and GD Library. It is as simple as drawing four quadrants of a circle over the four corners of the image. The circle itself has to be transparent.
此脚本显示如何使用 PHP 和 GD 库将圆角应用于图像。它就像在图像的四个角上绘制圆形的四个象限一样简单。圆圈本身必须是透明的。
This script, on the other hand, generates rounded corner graphicsfor HTML or CSS based solutions. It generates the four corners that you can overlay over an image using CSS positioning or HTML tables.
另一方面，此脚本为基于 HTML 或 CSS 的解决方案生成圆角图形。它生成四个角，您可以使用 CSS 定位或 HTML 表将其覆盖在图像上。

It can be done using php-gd, but I ended up passing that task to the browser, using CSS:
它可以使用 php-gd 完成，但我最终使用 CSS 将该任务传递给浏览器：
<img src="photo.jpg" width="42" height="42" alt="My cool photo" style="border-radius: 15px; -moz-border-radius: 15px;" />
<img src="photo.jpg" width="42" height="42" alt="我的酷照片" style="border-radius: 15px; -moz-border-radius: 15px;" />

There are a lot of options available, you can find them using Google. The easiest way though is using the Thumbnailer. It's as simple as two lines of code:
有很多可用的选项，您可以使用 Google 找到它们。最简单的方法是使用Thumbnailer。它就像两行代码一样简单：
// make an object
$th=new Thumbnailer("your-photo.jpg");
// create a 120x90 thumb and round its corners
$th->thumbFixed(120,90)->round()->save("your-thumb.jpg");
Fun it is, isn't it? :) There are a lot of other options available. The corners will be antialiased.
很有趣，不是吗？:) 还有很多其他选项可用。角落将被抗锯齿。

Instead of modifying the image, why not just wrap it in some HTML that has images at each corner that overlay the original to provide the appearance of rounded corners?
与其修改图像，不如将其包装在一些 HTML 中，每个角都有图像，覆盖原始图像以提供圆角的外观？
By doing the image editing in your .php script, you're going to put undue load on your web server, and that means your application won't scale well.
通过在您的 .php 脚本中进行图像编辑，您将给您的 Web 服务器带来不必要的负载，这意味着您的应用程序将无法很好地扩展。

GD is great for image manipulation, but it would be much easier for you and much easier on your server if you used CSS.
GD 非常适合图像处理，但如果您使用 CSS，它对您来说会容易得多，而且在您的服务器上也会容易得多。
