Can we create transparent jpg's using the com.sun.image.codec.jpeg package? I have some .jpg files created from xpm files (using a C++ tool) that are transparent AND they show up correctly (ie transparent where appropriate) when textured on QuadArrays in our Java3D app. We have used the image package to create .jpg's without alpha using the BufferedImage approach but cannot get a JPEGEncodeParam object created from a Raster if we use alpha. Here is a code fragment: > > BufferedImage bi = new > > BufferedImage(width,height,BUFFEREDIMAGE.TYPE_4BYTE_ABGR); > > ColorModel cm = bi.getColorModel(); > > Raster ra = bi.getAlphaRaster(); > > //fill raster in a loop > > ra.setPixel(x,y,abgr); //where abgr is a 4 byte array > > //Create encoder > > BufferedOutputStream bos = new BufferedOutputStream(fos); > > JPEGImageEncoder jie = JPEGCodec.createJPEGEncoder(bos); > > //Create param object using raster and color_id > > int cid = jie.getDefaultColorId(cm); > > JPEGEncodeParam jep = new JPEGEncodeParam(ra,cid); Any help is appreciated..
