Inline image from email html

[Jure]

Hello.

I import a HTMLBody to a RadDocument. It's coming from Outlook.MailItem, so I also have attachments.

Dim provider As HtmlFormatProvider = New HtmlFormatProvider()
Dim doc = provider.Import(currentMail.HTMLBody)

The HTMLBody contains something like this:

<img src="cid:ii_kuchydn60" alt="logo.jpg" width="145" height="89">

So the displayed image element is just a rectangle with a red x.

Is there a way to also import an image / Outlook.Attachment to the document (other than saving the attachment and then modifying src property of img tag)?

Edit: based on Tanya's answer I was able to do this, it works but I'm not sure how safe it is:

 Private Sub LoadImageFromUrl(sender As Object, e As LoadImageEventArgs)

        Dim att = (From a As Attachment In currentAttachments Where a.FileName = e.ImageElement.Alt).FirstOrDefault

        If att IsNot Nothing Then
            Dim tempFile = IO.Path.GetTempPath + att.FileName
            att.SaveAsFile(tempFile)
            e.ImageElement.UriSource = New Uri(tempFile)
            e.Handled = True
        End If

    End Sub

Hi Jure,

You can use the LoadImageFromUrl event of the HtmlFormatProvider's ImportSettings to read the image and pass it to the import logic. The event allows you to set the UriSource of the image, so you will need to have it saved.

private void ImportSettings_LoadImageFromUrl(object sender, LoadImageEventArgs e)
{
    string uri = e.Url;
    // Modify uri to point to the image
    e.ImageElement.UriSource = new Uri(uri);
    e.Handled = true;
}

Hope this is helpful.

You can also use the Init() method of ImageElement to pass a Stream instance containing the image.

Thanks. I updated my question with a solution. I don't know how to get a Stream from the attachment without saving it first.
