How To Pass A Raw System.Drawing.Image To An .ashx

Jun 4, 2010

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?

C# - "Parameter Is Not Valid" Exception From System.Drawing.Image.FromStream() Method?

Aug 27, 2010

I 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.

if (!afuImageFile.IsUploading && afuImageFile.HasFile)
{
System.Drawing.Image imgFile = System.Drawing.Image.FromStream(afuImageFile.FileContent);
}

the afuImageFile is an AsynFileUploader control in Ajax Tool Kits. afuImageFile.FileContent is a HttpInputStream.

C# - System.Drawing.Color - Set Color Property Of Car Object In Javascript And Maintain Through The Server?

Oct 19, 2010

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. I would like to change the color of the car in Javascript, but I am finding it difficult to do so without adding another parameter that takes in the color as a string and is then translated at the server. Are there any ideas on how to set the Color property of the Car object in Javascript and maintain it through to the server?
