i tried putting the COLOR_ID as COLOR_ID_YCbCrA ,but still it throws the same error.> may be something i am doing wrong..
Can you post your current code as a standalone example?
reg writing a rendered image to remove alpha any links provided will be of great help. many thanks
Well there are a number of examples in sources/org/apache/batik/ext/awt/image/rendered
Your best bet will probably to implement this as a 'background color' operation, so the user can provide a solid color to "fill in" the transparent regions. The easiest way to do this would be to wrap the two (source w/ Alpha, and generated w/o alpha) rasters (which is what rendered images compute) into BufferedImages (simply provide the ColorModel from the RenderedImage) Then fill the dest with the solid color and draw the source BufferedImage over the dest.

hi thomas, many thanks,i did modify the code that takes the band. i am getting the floowing error /* Exception breakpoint occurred at line 158 of JPEGParam.java. java.lang.IllegalArgumentException: NumComponents not in sync with COLOR_ID
Ooops, sorry, the SVG Image has alpha so you will either need to write a small renderedImage to remove the Alpha (way beyond the scope of this list) or use COLOR_ID_YCbCrA (The 'A' is for Alpha).
*/ i also noticed that Abstractred.getSampleModel i.e im.getSampleModel() is fetching no value. i might be doing something wrong.

Hi Techno,
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);

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.
