InfoPath Dev

Pasting an image into a Infopath rich text box and submitting the form results in an xml inline image of the format

<img style=".." src="msoInline/f4b19f6546fa4081" xd:inline="...." />

Using System.Convert.FromBase64String the xd:inline innertext can be converted to an image.

However how do I convert the src innertext to something readable. And does it contain the mime type of the image, which would be usefull ?

The src attribute contains a guid that refers to the image. I believe you'll want to look at the header of the actual base 64 data for the mime type, but not exactly sure. I'll check and get back to you.

I tried reading the first 16 bytes of the converted Base64 and converted these into a GUID which I used to construct a System.Drawing.Imaging.ImageFormat.

However the System.Drawing.Imaging.ImageFormat does not return any of the available image types.

It does recognize something because the object returns: [ImageFormat: e0ffd8ff-1000-464a-4946-000101010096] when submitting a jpg image.

What am i doing wrong ?

Sorry for the delay.
