hi ,
thanks for the info.
i tried using TiledImageTranscoder
1. it was saying that the constrcutor is protected.
The file has it's own main which was intended to construct the
Transcoder, but I don't think there is much of a problem making it
public for use in a larger application.
2.i made the constructor public and tried instantiating i tried in the
following way
====================================
FileOutputStream fos = new FileOutputStream("d:\\gvs.tiff");
TiledImageTranscoder tit = new TiledImageTranscoder();
tit.addTranscodingHint(KEY_WIDTH, new Float(10240));
tit.transcode(new TranscoderInput("file:" + "d:\\test.svg"),
new TranscoderOutput(fos));
====================================
it was creating a file as large as 400MB.i am not sure where iam commiting
some mistake.please help me out.
I don't think there is a mistake, the Tiff file is uncompressed,
so assuming a mostly square document: 4*10,000*10,000 = 400,000,000 bytes = 400MB.
(That is 4 bytes per pixel * 10,000 pixels across * 10,000 pixels down).
thanks

Hi,
I had the same problem several months ago, you can use the
TiledImageTranscoder instead of your JPEG transcoder, of course you need
to change "TIF" to "JPEG" in the code. This transcoder doesn't use
BufferedImages but RenderedImages, so it decreases dramatically the
memory consumption.
The source is in the "contrib" area of the CVS, thanks to Thomas.
Actually, you can't just replace TIFF with JPEG in the code because
there is no JPEG encoder capable of taking a rendered image and transcoding
it to a JPEG file (Actually I think javax.imageio may have one but we
are currently based on JDK 1.3 so in that context we don't have it).
But it is true that if you can switch to using TIFF then the tiled
transcoder
is _much_ better for very large images.

hi all ,
i am trying to transform a large svg into an jpg image using batik jpeg
transcoder and i am encoutering with outofmemoryerror.
when the transcode method is called from the jpegtranscoder.
1.jpegtrascoder---------->>>>>2.imagetranscoder.transcode()----------->>>>3.
Staticrenderer.repaint()----------->>>>>>4.Staticrenderer.updateWorkingBuffe
