How do I identify the file format in a scan job?

You can identify the file format with the value of Content-Type in the Response Header.

http://gw.machine.address:54080/rws/service/scanner/jobs/1bbr3nmj4zn6/file

This specification is based on the SmartSDK scan WebAPI ( ./xx_Release/doc/en/webapi/320-04-010.htm )

Http Header :Content-Type 

Value:   

1) image/tiff
2) image/jpeg
3) application/pdf

The ScanExRi sample code handles the file type with the following code:

private class GetFileTask extends AsyncTask { : private boolean getFile(staring JobID) throws URISyntaxException, ClientProtocolException, IOException { : if (status == HttpStatus.SC_OK) { String type = response.getHeaders(HEADER_CONTENT_TYPE)[0].getValue(); if(type.equals(CONTENT_TYPE_TIFF)) filePath = "tiff " + size + "byte"; else if(type.equals(CONTENT_TYPE_JPEG)) filePath = "jpg " + size + "byte"; else if(type.equals(CONTENT_TYPE_PDF)) filePath = "pdf " + size + "byte"; Log.i(LOGTAG, "getFile storeFile : " +filePath); : } }

** We return the jobSetting(JSON) after the scan is completed because the scan parameters could be changed during a single scan job.  When the document is set on the platen, we support changing the scan parameters while waiting for the next document.  The jobSetting(JSON) contains the final parameters set.
