Actually, this line precedes my lines below ;-)
But good to know it works somewhere else in the servlet environment (are you
really able to save the result image?) so it seems to be my fault.
I would be grateful for a link to any working example code... I hope there
is no any special magic behind, just a small mistake from my side...

Thanks for this info. It led me to try also JPEG output, but the result is
the same. I suspect the way of closing the final stream. I think the browser
can display partial data but as they are unfinished properly, it made him
puzzled a bit.
Transcoding via command line is Ok in all cases.

No file is created in FF so there is nothing to analyze. And that MSIE BMP
file is the standard image. It is probably a kind of the screenshot of an
internal canvas.
Here is the final part of my code:
TranscoderOutput output = new TranscoderOutput(response.getOutputStream());
t.transcode(input, output);
// I've tried to find any closing method of the 'output' object,
// but still without success. The following way also doesn't help
//
// output.getWriter().close();
ServletOutputStream out = response.getOutputStream();
out.flush();
out.close();
Any other ideas?
