    <p>I am using JNA. and i am getting byte array of raw data from my c++ method. Now i am stuck how to get buffered image in java using this raw data byte array. I had tried few things to get it as tiff image but i dint get success. this are the code i tried so far. here my byte array contains data for 16 bit gray scale image. i get this data from x-sensor device. and now i need to get image from this byte array. </p> <p><strong>FIRST TRY</strong></p> <pre><code>byte[] byteArray = myVar1.getByteArray(0, 3318000);//array of raw data ImageInputStream stream1=ImageIO.createImageInputStream(newByteArrayInputStream(byteArray)); ByteArraySeekableStream stream=new ByteArraySeekableStream(byteArray,0,3318000); BufferedImage bi = ImageIO.read(stream); </code></pre> <p><strong>SECOND TRY</strong></p> <pre><code> SeekableStream stream = new ByteArraySeekableStream(byteArray); String[] names = ImageCodec.getDecoderNames(stream); ImageDecoder dec = ImageCodec.createImageDecoder(names[0], stream, null); //at this line get the error ArrayIndexOutOfBoundsException: 0 RenderedImage im = dec.decodeAsRenderedImage(); </code></pre> <p>I think i am missing here. As my array is containing raw data ,it does not containthen header for tiff image. m i right? if yes then how to provide this header in byte array. and eventually how to get image from this byte array?</p> <p>to test that i am getting proper byte array from my native method i stored this byte array as .raw file and after opening this raw file in ImageJ software it sows me correct image so my raw data is correct. The only thing i need is that how to convert my raw byte array in image byte array? </p>

    1. COI was able to get the raw byte array converted to image by following the link https://forums.oracle.com/forums/thread.jspa?threadID=1261950 (I had to convert byte offset to {3,2,1,0} as suggested in the forum for both bandOffsets and in raster.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
