Image Extraction from a Image Field
Gervais...@gmail.com
I've made a form in LiveCycle and in it I have an image field where a
user can insert an image into the form. When the submit the form, the
image is embedded in the xml file and when I import it back into the
form the image is still there, yay.
My problem is that I would like to be able to take that image out of
the form when it gets submitted back to me. Either have it attached
separately from the xml file or some other way.
Hope someone can help.

You (or we) could write a tool to extract the data from teh XML, and
convert it back into a file.
This could be done on the client, or the server.
The easiest way would be to import the XML file back into the original
form using Acrobat, and then use the Snapshot tool to take a snapshot.
Very low tech, but the easiest/cheapest way to go.
You will potentially lose quality though...

The snapshot tool wouldn't be good enough as the form is a request for
reports and the user has the ability to enter a client logo for use in
the reports and there would be too much chance of loss of quality.
Isn't there some way of maybe not using an image field but maybe
placing a button which would prompt the user for a file which gets
added as an attachment along with the xml file when submitted?
PS
I found this post somewhere else:
http://www.acrobatusers.com/forums/ask_an_expert/questions/view/2226/
I don't know JavaScript but I tried to add
"event.target.browseForFileToSubmit();" to a text field and a button
as JavaScript for mouse up event and nothing happens when clicked.

Javascript)
var myDoc = event.target;
// This will prompt the user to import an external document and save
it to an attachment called "profile.xml"
myDoc.importDataObject("logo");
You will need to either have your customers use Acrobat, or Reader
Extend the form, as attachments are not supported by Reader.
We'd be happy to provide the Reader Extensions license if you're

I did that and the open file dialog came up, I selected the file, it
imported the file as an attachment to the pdf but when I submitted it,
there was no additional xml file and when I imported the outputted xml
file back into the form, the attachment wasn't in it.

When working with Attachments, you would have to submit the PDF ...
not the XML file. The PDF acts like a container for all the elements.
On the server you can extract the attachments from the PDF file.

A pity.
You can still presumably use it, at your own risk, if you've purchased
LiveCycle. Or Cold Fusion?

I think if can be requested but only for people who have purchased other LC
components. Not sure about CF but I would like to propose that it makes
sense.

the importDataObject and set the form to submit as pdf which kept the
attatchments in the file. Perfect, that'll do. Thanks all
