移动Safari图片上传和放大器;它们的大小 [英] mobile safari image upload & their sizes

问题描述

好了，所以尽可能多的知识，野生动物园移动现在允许文件上传，通过相机或图像库。

Ok so as many of know, safari mobile now allows file uploads through camera or image library.

的'问题'是，当图像从相机拍摄的，它被发送，因为它是，这意味着它是在内存非常沉重的（我认为这是大约2或3甚至在iPhone 4 MB）。

The 'problem' is that when the picture is taken from the camera, it is sent as it is, meaning it is very heavy in memory (I think it's around 2 or 3 mb even on iphone 4).

这使得上传很慢，也消耗带宽（移动不好）。你知道，用＆LT;文件/＆GT; HTML标签，还有一个办法说的iOS：哎，你能不能也COM preSS的图片几分？ - 就像当所述图像经由电子邮件发送应用程序它正在做

This makes the upload really slow and also bandwidth consuming (not good for mobile). Do you know if, with the <file /> html tag, there is a way to say to iOS: "hey, can you also compress the picture a bit?" - like it's being done when said images are sent via the mail app.

先谢谢了。

推荐答案

有对一个库：<一href=\"https://github.com/gokercebeci/canvasResize\">https://github.com/gokercebeci/canvasResize

它的工作原理是把图像到＆LT;帆布/＆GT; （比原图像更小），则获得的图像数据，所以你可以将它发布到你的服务器

It works by putting the image to a <canvas /> (smaller than original image), then getting the image data so you can post it to your server.
