Question

private static byte[] get_byte_data(BufferedImage image)
{
    //WritableRaster raster   = image.getRaster();
    DataBufferByte buffer = (DataBufferByte)image.getRaster().getDataBuffer();
    return buffer.getData();
}

I get the stated class cast exception while executing the above piece of code. I need the byte[] array to be returned. i.e the bytes of the bufferedimage.

Answer 1

The raster data is not necessarily bytes.

if (image.getRaster().getDataTypeSize() == 1), then you can use getElem(int bank, int i) for all banks and all elements, and store the results in the desired array. I don’t see anything more direct.
