      Does anyone have any experience in sending image files within an HL7 message?  If so, I would love to discuss it with you as I’m being asked about building an interface to do this.

      Thanks…

          Tom,

          We do interfaces with PDFs that have images embedded in them.  Is that the type of interface you are talking about?  We use Base64/Mime encoding to get the data through the interface engine.

            Same here: recently we are getting embedded PDFs in ORU messages. The embedded PDF is base64 encoded when we receive it. We take this base64 part, decode it and write it to a file. Then the receiving system gets a message with a pointer to this PDF-file.

            Here is the part where the file is written; the pdf-part is in $b64:

            Code:

                                   package require base64
            …

                                   set fileId [open $fileout “w”]
                                   fconfigure $fileId -translation binary
                                   puts -nonewline $fileId [::base64::decode $b64]
                                   close $fileId

            Remember to configure the file as binary, or you won’t be able to open the pdf correctly.

            The other way around (receiving a pdf-file and sending it out as embedded) shouldn’t be any more difficult.

                Tom you can use a cURL call or the web services adapter to fetch the image.   You’d then want to base64 encode it before you store it into the HL7 message.
