我有一类实现IhttpHandler的类，在该类中我根据post参数绘制图像.我在使用XMLHttpRequest并从处理程序类检索响应的javascript中.现在，我想在图像对象中设置此响应，以便在浏览器中显示图像.

有人可以帮我在图像对象中设置HttpRequest的responseText吗?

Hi friends.
I want to set HttpRequest response text in Image object using javascript.

I have one class with implementing IhttpHandler where I am drawing image based on post parameter. I have javascript where I am using XMLHttpRequest and retrieve response from handler class. Now I want to set this response in image object so Image is shown in browser.

Can anybody help me to set HttpRequest''s responseText in image object?

推荐答案

实际上您的responseText包含什么?就像呈现的img一样吗?

Actually what your responseText contains?Is it like rendered img?

我有一个类在其中绘制Bitmap对象并写入OutputStream.

请看下面的代码.

< pre> EditorDrawing编辑器=新的EditorDrawing();
位图bitmap = editor.drawCanvas(400，500);
System.IO.MemoryStream m =新的System.IO.MemoryStream();
bitmap.Save(m，System.Drawing.Imaging.ImageFormat.Png);
bitmap.Dispose();
m.WriteTo(context.Response.OutputStream);
m.Dispose();</pre>

谢谢

I have a class where I am drawing Bitmap object and write to OutputStream.

Please look at below code.

<pre> EditorDrawing editor = new EditorDrawing();
Bitmap bitmap = editor.drawCanvas(400, 500);
System.IO.MemoryStream m = new System.IO.MemoryStream();
bitmap.Save(m, System.Drawing.Imaging.ImageFormat.Png);
bitmap.Dispose();
m.WriteTo(context.Response.OutputStream);
m.Dispose();</pre>

Thanks
