I had some images on the IBM I server, when transferred to a Windows or Linux machine using FTP/ascii where downloaded properly.

My goal was to embed those images into a XML as part of a Web Service Response, so I 1) streamed those images 2) and base64_encode them as I would regularly would do it with PHP or any other language, but it didn't work. The image was not properly being shown up.

After looking in the several references on the web, I found out that the way to do it is to 1) stream it, 2) convert to ASCII, 3) base64_encode; now I have on the IBM i a REST web service returning a XML with an image on it.

I want to encode a TIF image stored on the IFS and to embed it into an

I know that by open() the IFS file, then QDCXLATE(), and
base64_encode() -of course using Scott's tools- do the magic, but has
to be by reading in a loop the buffer returned by open().

However, I want to save some extra programming by avoiding the loop
and convert the full streamed file in one single step (I'm already
using CGIDEV2-LoadStreamFile that returns the streamed file).

I found that I can use 'iconv' API from QTQICONV service program to do
this conversion, does somebody can share an example of parameters to
be used for 'iconv'?.


Perhaps just my ignorance, but where is there a need for dealing with character conversions when the original data is "image"?
