Bitarray Email

[LiquidPixel]

I have bitmapData (bitArray) coming out of Flash and being parsed into a Bitmap object in ASP.NET. I can get the image to render on the screen via:

Bitmap.Save(Response.OutputStream, ImageFormat.Jpeg);

Obviously this writes during the response call BUT what I need to do is have this image not render on screen but email to a user as either an attachment or inline image. I simply don't know how to package and/or render the image to an email.

Subsequently I would have the page Response.Redirect to a "your info has been sent page".

Does someone know how to render and/or inject the image and send it via email???

Any help here would be greatly appreciated.

Thanks

You would need to save that Stream to a file. So instead of Bitmap.Save(Stream) do Bitmap.Save("file.bmp");

Create an email with attachment, send.

Then delete the image (unless you need to keep it after ti's sent)

HTH

Well I have tried this BUT the file doesn't appear in a physical location. Do I need to use a File.IO arrangement???
Should I see a physical file named file.bmp. I also have tried a generic name like image.jpg. It also does not exist.

I do get the theory on how this is done but I am not a server-side programmer so I really need specifics on how to do this. I am also not hugely familiar with the .Net libraries.

ASP is definitely receiving the data and I know how to send an email using ASP. So I am really looking for a thorough explanation on how to take the bitmap (created by the bitArray) and access that object for the email.

Obviously the Bitmap object exists in my program because I can access it in the Response functionality. Is there a way I can take that object without saving it to stream or file and embed it to render visually within an email message.

Here is the Page_Load method for this

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

protected void Page_Load(object sender, EventArgs e)
{
// Retrieve the pixel data from Flash
string pixelData = Request["pixels"];

int width = int.Parse(Request["width"]);
int height = int.Parse(Request["height"]);

Bitmap bmp = null;

string curPixelColor = String.Empty;

int x = 0;
int y = 0;

if (pixelData != String.Empty)
{
bmp = new Bitmap(width, height);

for (int i = 0; i < pixelData.Length / 6; i++)
{
curPixelColor = pixelData.Substring(i * 6, 6);
bmp.SetPixel(x,y, ColorTranslator.FromHtml("0x" + curPixelColor));

if(x==width-1)
{
x = 0;
y++;
}
else
{
x++;
}
}
}


Response.ContentType("image/jpg");
bmp.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
bmp.Dispose();
Response.End();

}

You will have to specify the filename and path for where it needs saving. See the help files for example:

I figured this out last night using MapPath() thanks for your help guys.
