RE: Streaming SVG Document without creating temporary file

Tue, 20 Jun 2006 01:53:20 -0700

Thanks Javid and Thomas for the replies,

 

Have got it working now after reading your suggestions.... just to close the thread in case anyone else is looking for similar in the future, required code looks something like this (of course adding the flushing/closing of streams).....

 

            TranscoderInput input = new TranscoderInput(doc);

            OutputStream ostream = new ByteArrayOutputStream();

            TranscoderOutput output = new TranscoderOutput(ostream);

            t.transcode(input, output);

            ByteArrayOutputStream result = (ByteArrayOutputStream)output.getOutputStream();

byte[] bytes = result.toByteArray();

 

Thanks as ever for the help,

 

Cheers,

Dylan.

   Well the transcoder can take _any_ OutputStream.  Usually the

servlet provides an output stream that could be passed directly to

the Transcoder.  Alternately you can use java.io.ByteArrayOutputStream

which simply stores all the content in memory which you can retrieve

as a byte[].
