I use to store image in bytes and able to convert it to system.drawing.image but not sure how to render it on page
View 2 RepliesI created image from byte array
System.Drawing.Image newImage;
using (MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
{
ms.Write(imageBytes, 0, imageBytes.Length);
newImage = System.Drawing.Image.FromStream(ms, true);
}

I am developing an application that stores images as Base64 strings in xml files. I also want to allow the user to crop the image before saving it to the file, preferably all in memory without having to save a temp file, and then delete it afterwards. In order to display the newly uploaded image, I need to create a HTTP handler that I can bind the asp:Image to. The only examples for doing this online require passing the .ashx an ID and then pulling the image from a DB or other data store. Is it possible to somehow pass the raw data to the .ashx in order to get back the image?

View 2 RepliesI got a hard time with the Image.FromStream method in my website. The code below works perfect on my computer. But when I uploaded it to the test server, it always gives me "Parameter not valid" exception.

I have a class (let's call it Car) that has a property of type System.Drawing.Color (Call it CarColor). I have a script service function that uses this Car class as a return value, which works just fine. I then have another script service function that takes a Car object as a parameter.
