ok, i have done it :
[code]
GZIPOutputStream gz = new GZIPOutputStream(new
FileOutputStream(tempFile));
// TranscoderOutput output = new TranscoderOutput(new
OutputStreamWriter(new FileOutputStream(tempFile), "UTF-8"));
TranscoderOutput output = new TranscoderOutput(new
OutputStreamWriter(gz,
"UTF-8"));
try {
trans.transcode(input, output);
} catch (TranscoderException ex) {
ex.printStackTrace();
}
[/code]
it's compiling but the svgz file is empty. may i use the wrapper
incorrectly?
thank you
i have found something to help me but not to give a solution of that. My
servlet generates real svg files
and when the second servlet is called to send the svg file to the web
client, i "gzip" the outputsteam of the HttpServletResponse. it works.
