dip::FixedOutputBuffer class

An output buffer implementation that cannot be resized.

The constructor takes a pointer to the already allocated buffer. The caller remains the owner of this buffer. If the buffer is not large enough to contain the full output, an exception will be thrown. The first dip::FixedOutputBuffer::size bytes of this buffer will contain the encoded image data after the image writing function has done its thing.
