Decoding base64 Stream to image

rated 0 times [ 88] [ 1] / answers: 1 / hits: 27904 / 12 Years ago, mon, october 15, 2012, 12:00:00

I am sending base64 encoded image from client side using javascript (I am creating Screenshot uploader applet for asp.net application using http://supa.sourceforge.net/) and this sends an ajax request to server to store the image. At server I am using HttpContext in GenericHanlder in asp.net application.

How to convert image data from HttpContext to image at server?

First, you need to convert the base 64 back into bytes:

byte[] data = System.Convert.FromBase64String(fromBase64);

Then, you can load it into an instance of Image:

MemoryStream ms = new MemoryStream(data);

Image img = Image.FromStream(ms);

If you want to save it to a file instead, use System.IO.File.WriteAllBytes
