I have tried to do this rasterization, but I cant get the code/parameters
right. How do I easily make this rasterization at a lower resolution ?
Since I am really stuck, code samples would be gratefully accepted.
For now, my code just looks like :
// create a JPEG transcoder
TIFFTranscoder transcoder = new TIFFTranscoder();
// create the transcoder input
String svgURI = new File("Images/TestImage.svg").toURL().toString();
TranscoderInput input = new TranscoderInput(svgURI);
// create the transcoder output
OutputStream ostream = new
FileOutputStream("Archived_Images/TestImage.tif");
TranscoderOutput output = new TranscoderOutput(ostream);
// save the image
transcoder.transcode(input, output);
// flush and close the stream then exit
ostream.flush();
ostream.close();
System.exit(0);
So could the helping hand show me where/how to fill in the missing code
to do this lower reolution approach ? As I wrote before, I dont know which
classes/librairies/methods to use...
Thanks in advance
/Gergely

So I thought about this again, I missed a factor of 1000. You are
asking for about 100,000 to 1 compression. Your 4GB image must be
around 30,000 by 30,000 pixels who gave you a requirement of 50K
bytes? It's insane!
Perhaps you really want to rasterize the image at a lower
resolution? Like screen resolution? This would make a _lot_
more sense with the 50K figure.
