OBE or Optimised Bitmap Encoding is a new technology developed specifically for the Oric to reduce an images memory usage by only storing the bytes that are present in the graphic.
OBE holds the shape of the graphic rather than a rectangle of memory expanded to encompass it.
Found this version was not working, have corrected now and uploaded(still V1.0)
First version released. OBE has already been used for the windmill vanes in Wurlde.
