This section supplies some hopefully useful information which may not be immediately apparent elsewhere.
Speed?
If you do not have an FPU then set the INTEGER parameter to YES. Even if you do have an FPU this may still make things run faster.
If it still slow then try changing DX and DY to 1 (or more).
If you have lots of memory then setting the precalculate part of MODE should help.
What MODE?
This depends on the type of Morph.
If you are, say, rotating some text on a background, then it is probably best to set the stationary part. You would NOT want to set the precalculate once part.
If you are morphing, say, two faces where the points do not move much between the first and last image then it may be best to set the precalculate part (provided you have enough free memory). Setting the Delaunay part may also be a good idea.
Setting search is probably not a good idea.
Not enough memory for MPMorph
If you run out of Chip memory when trying to load large images then try setting ZOOM to OFF.
