- Eps files generated with 'print -deps' are huge. Unecessarily so it
- seems. They contain, at least under 4.0, a section with no information:
-
- %%BeginPreview: 560 420 1 420
- %ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
- ...
- %%EndPreview

- MathWorks has always failed to generate good Encapsulated PostScript.
- The PostScript Language Reference manual states that only required header
- comments are:-
-
- %!PS-Adobe-3.0 EPSF-3.0
- %%BoundingBox llx lly urx ury
-
- The preview image is required for Encapsulated PostScript interchange
- format (EPSI) files, but matlab's print refers to EPSF files, which do
- not require the image.
-
- I believe that MathWorks had several discussions about this, and I'm
- glad to say that version 4.0a corrects this feature, so the print
- command now has an optional "-preview" argument.
-
- I wish that MathWorks get its house in order and generate the correct
- BoundingBox for its EPS files.
