      Hello,

          I am reaching out to see if anyone has been able to combine/concat multiple .png files into one embedded base64 in a TCL script?  Meditech scanned in documents are stored as one .png per page.  The HL7 message sends one file pointer per OBX.  

          I am looking to first loop through the OBX’s and pick up each file, somehow combined this to one big file, then send base64 out to the vendor.  I am currently able to embed one file, but not sure how to get them all into one embedded OBX.  

      Thanks,

      Jay

          I think you need to know the final file format (PNG?) and what formats and encodings the vendor can support. Normally PNG files only contain one image, so it seems strange to only send one PNG. If you want to send multiple PNGs, then there are various options. You could put the PNGs in a ZIP file, base64 encode it and stick it in an OBX, but could your vendor process that? You could base64 each PNG separately and send multiple OBX segments. That seems like how it would usually be done.

            Thank you!  I will work with the vendor to send them multiple OBX’s
