问题描述
我想知道什么是动态调整图像大小的最佳，最快和资源最有效的方法？我有想法在请求时动态地从照片库生成缩略图和特殊尺寸的图像。
I was wondering what is the best, fastest and most resource efficient way to resize images on the fly? I have the idea of generating thumbnails and special sizes of images from a photo gallery on-the-fly when they are requested.
这是个好主意吗？什么是最好的方式？
Is this a good idea? and what is the best way?
PHP，Imagemagick，litespeed服务器
PHP, Imagemagick, litespeed server
推荐答案
我已经使用Imagemagick成功创建了一个动态图像重构应用程序。性能很好，我可以通过一个宁静的请求调整大小/裁剪/水印/重新格式化等。我使用memcache来缓存重构图像的二进制blob，这给我带来了巨大的性能提升。
I have successfully created a on the fly image refactoring application using Imagemagick. The performance is great and I am able to resize/crop/watermark/reformat etc all via a restful request. I use memcache to cache the binary blob of the refactored image and this gives me a massive performance boost.
编辑：我使用了Java Imagemagick libs最初并且一直存在问题，PHP库是更好的imho（这是大约一年前，它可能是Java库已经改进）
I used the Java Imagemagick libs initially and kept running into issues, the PHP libs are far better imho ( this was about a year ago, its possible that the Java libs have improved )
