thanks for the input thomas, i think saving image of size 400 mb of an image cant be afforded by us.
Well, you might try using one of the supported forms of compressed Tiff. This includes JPEG Compression. The second argument to the TIFFImageEncoder is a TIFFEncodeParam object. You can construct one and call:
param.setCompression(TIFFEncodeParam.COMPRESSION_JPEG_TTN2);
To turn on JPEG compression of the image data (the file is still a Tiff file).
The encoder also supports, COMPRESSION_PACKBITS (a run length encoding), and
COMPRESSION_DEFLATE ("gzip" compression). To be honest I've never really tried
either of these but the TIFF Encoder we use (from JAI) should support them.Also these are getting pretty far "off the beaten path" for Tiff files so what ever software you are using down stream may or may not be able to read them.
i tried the other option of increasing the memory of java while starting my tomcat(Xmx512m ),i observed an improvement but still it seems to choke the memory.Is there any plan of batik enhancing the JPEGTranscoder?.
I don't have any plans. The biggest problem is that the com.sun JPEG encoder which we use takes the entire image at one time (no tiled interface). BTW for a 400MB image you will need to give it at least a Gig of memory as I know it needs to copy that image at least once for output (800MB).
thanks a lot for the support. regds GVS

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 GVS

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
1.jpegtrascoder---------->>>>>2.imagetranscoder.transcode()----------->>>>3.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.
Staticrenderer.repaint()----------->>>>>>4.Staticrenderer.updateWorkingBuffe
rs()------>>>>5. Raster.createWritableRaster().after this i am geting the
outofmemoryerror.
when i debug the code actual wrror is coming in the in databufferInt class.
would you please send me the code for correcting this problem in the batik
thanks a lot
