-/**
- * \ingroup gdcmFile
- * \brief Copies at most MaxSize bytes of pixel data to caller's
- * memory space.
- * \warning This function was designed to avoid people that want to build
- * a volume from an image stack to need first to get the image pixels
- * and then move them to the volume area.
- * It's absolutely useless for any VTK user since vtk chooses
- * to invert the lines of an image, that is the last line comes first
- * (for some axis related reasons?). Hence he will have
- * to load the image line by line, starting from the end.
- * VTK users have to call GetImageData
- *
- * @param destination Address (in caller's memory space) at which the
- * pixel data should be copied
- * @param MaxSize Maximum number of bytes to be copied. When MaxSize
- * is not sufficient to hold the pixel data the copy is not
- * executed (i.e. no partial copy).
- * @return On success, the number of bytes actually copied. Zero on
- * failure e.g. MaxSize is lower than necessary.
