2001 JI Open Discussion Wrote: The following is the explanation of how you can do it Use the SUN Java Advanced Imaging Library, you can get it from : http://java.sun.com/products/java-media/jai/downloads/download.html and this must help you convert the TIF image to an awt Image and which can be passed into Jasper Reports : ByteArraySeekableStream stream = new ByteArraySeekableStream(binaryData); ParameterBlock params = new ParameterBlock(); params.add(stream); // Specify to TIFF decoder to decode images as they are and // not to convert unsigned short images to byte images. TIFFDecodeParam decodeParam = new TIFFDecodeParam(); decodeParam.setDecodePaletteAsShorts(true); // Store the decode parameters in a RenderingHints to be sent // to the operation registry, and eventually to the TIFF decoder. RenderingHints hints = new RenderingHints(JAI.KEY_TILE_DECODING_PARAM,decodeParam); // Create an operator to decode the TIFF file. RenderedOp image1 = JAI.create("tiff", params, hints); // Find out the first image's data type. int dataType = image1.getSampleModel().getDataType(); RenderedOp image2 = null; if (dataType == DataBuffer.TYPE_BYTE) { // Display the byte image as it is. log.debug("TIFF image is type byte."); image2 = image1; } else if (dataType == DataBuffer.TYPE_USHORT) { // Convert the unsigned short image to byte image. log.debug("TIFF image is type ushort."); // Setup a standard window-level lookup table. */ byte[] tableData = new byte[0x10000]; for (int i = 0; i < 0x10000; i++) { tableData = (byte)(i >> 8); } // Create a LookupTableJAI object to be used with the // "lookup" operator. LookupTableJAI table = new LookupTableJAI(tableData); // Create an operator to lookup image1. image2 = JAI.create("lookup", image1, table); } else { log.debug("TIFF image is type " + dataType +", and will not be displayed."); } // Attach image2 to a scrolling panel to be displayed. BufferedImage bi = new BufferedImage(image2.getColorModel(),image2.copyData(), false, new Hashtable()); Hi, What steps need to be followed to get it work. I'm so far that I have downloaded the SUN Java Advanced Imaging Library. Can you please help give me some clarity? Thanks, Gerard
