This is pretty close, but I would use the getDefaultJPEGEncodeParam that takes a number of bands:
jpegColorID = com.sun.image.codec.jpeg.JPEGDecodeParam.COLOR_ID_YCbCr;
jpegEncodeParam = com.sun.image.codec.jpeg.JPEGCodec.getDefaultJPEGEncodeParam
(im.getSampleModel().getNumBands(), jpegColorID);techno info wrote:
hi thomas, correct if i am wrong,is this way i create???. /* jpegColorID = com.sun.image.codec.jpeg.JPEGDecodeParam.COLOR_ID_YCbCr;
Raster tile00 = im.getTile(0, 0);
jpegEncodeParam = com.sun.image.codec.jpeg.JPEGCodec.getDefaultJPEGEncodeParam( tile00, jpegColorID); */

i am facing with similar problem of memory outburst when i try to convert svg to jpg. i tried the solution mentioned by you earlier to GVS.infact i am getting a null pointer exception. In the encode method of TIFFImageEncoder,it is calling encodeParam.getJPEGEncodeParam() to get the JPEGEncodeParam.the value of JPEGEncodeParam is coming as null.
So did you try providing a JPEGEncodeParam? As I said I've never actually used these TIFF formats.
