returning a picture from a webservice

[Ohad Young]

Hi,

I was wondering if it is possible to code a webservice that returns a
picture?
If so, How?

Thanks in advance, Ohad

Perhaps try converting the image to a base64Encoded string in the web
service?

Not sure if this is the best mechanism, but I've used it before to encode
binary data at it seems to work.

You can use WSE + DIME Attachments:

I think that's a better way to attach data than using
base64encoded strings..

If its a small bitmap
1. Convert it to a byte array.
2. Send over wire.
3. Desearialize from a byte array.

If its a big bitmap use WSE Attachments.
Current implementation of WSE uses DIME (which would be replaced in the
future by MTOM)

Hi all,

Thank you all for your quick response.
Since the pictures are small bitmaps, the most suitable option is the
byte array conversion.
Where can I find a code example for it?

Thanks again, Ohad

On Server:
[WebMethod]
public byte[] GetBitmap()
{
Bitmap bitmap = new Bitmap(@"c:\picture.bmp");
MemoryStream stream = new MemoryStream();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, bitmap);
return stream.ToArray();
}

On Client:
Bitmap GetBitmap()
{
localhost.BitmapService service = new BitmapService();
byte[] rawBitmap = service.GetBitmap();
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream(rawBitmap);
return (Bitmap) formatter.Deserialize(stream);
}

Hi Raj,

Thanks for the code example.
I'll try it :)
