图像在上传前调整大小 [英] Image resize before upload

问题描述

我需要为用户提供一种手段，以jpeg格式将照片上传到他们的网站。但是，这些照片的原始尺寸非常大，我想在上传前调整大小选项对用户来说非常轻松。似乎我唯一的选择是客户端应用程序，它在通过Web服务上载照片之前调整照片大小，或者在上传操作上调整照片大小的客户端JavaScript挂钩。第二个选项是非常试验性的，因为我没有JavaScript图像大小调整库，并且很难让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.

我确信这种情况并不常见，并且会对这样做的网站提出一些建议或指示。

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