Pixels are not allowed to span data elements. The data type can be DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, or DataBuffer.TYPE_INT. Each pixel must be a power of 2 number of bits and a power of 2 number of pixels must fit exactly in one data element. Pixel bit stride is equal to the number of bits per pixel. Scanline stride is in data elements and the last several data elements might be padded with unused pixels. Data bit offset is the offset in bits from the beginning of the <A HREF="../../../java/awt/image/DataBuffer.html"><CODE>DataBuffer</CODE></A> to the first pixel and must be a multiple of pixel bit stride. <p> The following code illustrates extracting the bits for pixel <code>x, y</code> from <code>DataBuffer</code> <code>data</code> and storing the pixel data in data elements of type <code>dataType</code>: <pre> int dataElementSize = DataBuffer.getDataTypeSize(dataType); int bitnum = dataBitOffset + x*pixelBitStride; int element = data.getElem(y*scanlineStride + bitnum/dataElementSize); int shift = dataElementSize - (bitnum & (dataElementSize-1)) - pixelBitStride; int pixel = (element >> shift) & ((1 << pixelBitStride) - 1);
