上传前调整图像大小 [英] Image resize before upload

问题描述

我需要为用户提供一种以 jpeg 格式将照片上传到他们网站的方法.但是，这些照片的原始尺寸非常大，我想让用户轻松地在上传选项之前调整大小.似乎我唯一的选择是客户端应用程序在通过 Web 服务上传照片之前调整照片大小，或者在上传操作上调整图像大小的客户端 JavaScript 钩子.第二个选项是非常暂定的，因为我没有 JavaScript 图像大小调整库，而且很难让 JavaScript 运行我当前的调整大小工具 ImageMagick.

I need to provide a means for a user to upload photos to their web site in jpeg format. However, the photos are very large in original size, and I would like to make the resize before upload option very effortless for the user. It seems my only options are a client side application that resizes the photos before uploading them via a web service, or a client side JavaScript hook on the upload operation that resizes the images. The second option is very tentative because I don't have a JavaScript image resizing library, and it will be difficult to get the JavaScript to run my current resize tool, ImageMagick.

我相信这种情况并不少见，如果您提供一些建议或指向执行此操作的网站的指示，我们将不胜感激.

I'm sure this is not too uncommon a scenario, and some suggestions or pointers to sites that do this will be appreciated.
