We’ve used this to handle 10s of thousands of transmissions successfully. The chunks are then re-assembled at the server and decoded. I can’t say if this would also be a problem for form submission but for Web Service calls it definitely was.To work around this attachments are each sent with a separate call and if the attachment is larger then about 64K we break the attachments into chunks and send them using multiple calls. In our case placing the attachment within the forms XML would result in submission calls that frequently exceeded 1MB and at that size failures were common (1 in 10). We do our submissions via web service calls and found during testing that trying to make a call with a large payload was problematic. We have been handling attachments now for a while and would like to pass on one little gotcha to watch out for. But of course, for this to work the consumer of your XML needs to be able to handle hex encoding as well.

The easiest and most reliable way to encode attachments in your XML data is to keep them in a hex encoding. One button uses the (slow) JavaScript encoding algorithm the other button uses Net.streamEncode and works pretty quickly. There are two buttons that will take the corresponding attachment, convert it to base64 and assign it to the image field value.

I’ve included this code in the sample just for interest sake.Ĭonversion to Base64 The form has an initialization script that displays a subform for each attachment. On a 140K image, it takes 10 seconds to encode. When I first looked at this problem I assumed that the Net.StreamEncode method wasn’t working so I wrote a base64 encoding JavaScript. However, when used in the context of encoding an attachment, it seems to work fine. To convert to a base64 encoding, use the Acrobat Net.streamEncode method: // Get a stream for the image attachment var inputStream = ('Smile.jpg') // Get a new stream with the image encoded as base64 var vEncodedStream = Net.streamEncode(inputStream, 'base64') // Get a string from the stream var sBase64 = util.stringFromStream(vEncodedStream) // assign the base64 encoded value to an image field sampleImage.rawValue = sBase64 We know there are issues with Net.streamEncode failing where content has null bytes. However, when your attachment is in a binary format, the standard way to include it in an XML file is to encode it as base64. If your attachment happens to be textual, then you can use util.stringFromStream to convert to a string value: var inputStream = ('MyNotes.txt') Notes.rawValue = util.stringFromStream(inputStream) The default encoding for binary attachments is a hex-encoding (each byte written as a 2 digit hex value). It returns a stream object with the contents of an attachment. The interesting method in our case is getDataObjectContents. Then are a set of methods for dealing with attachments: openDataObject, getDataObject, createDataObject, importDataObject, removeDataObject, getDataObjectContents, and setDataObjectContents.

#CONVERT OCTET STREAM TO PDF PDF#
Some scanners mail the scanned pdf file as an application/octet-stream with pdf extension. Take image attachments and use them to populate image fields Acrobat methods for attachments The acrobat document object has a property: dataObjects that returns an array of all the attachments in the current document. Take any attachments a user has added to the PDF and include it in a form submission or in a web service request. If you can do so, it opens up a couple of interesting possibilities. The end goal is to copy a PDF attachments into XML data. So I’ve tried again and had a little more success this time.

But then I saw a customer scenario that called for this capability, and then one of my regular commenters (Bruce) brought up the topic as well. I wasn’t happy with the outcome at that time, and I was going to leave it. Some time ago I experimented with PDF attachments - trying to add them to my XML data.
