Thierry,
I tryed to do what you said, but all the time I get an exeption:
Exception 400 incompatible with
org.apache.batik.transcoder.keys.LengthKey@ffb38
I just add thouse two strings:
pngTranscoder.addTranscodingHint(PNGTranscoder.KEY_WIDTH,
new Integer(width));
pngTranscoder.addTranscodingHint(PNGTranscoder.KEY_HEIGHT,
new Integer(height));
What am I doing wrong?
