[tex-k] Can't reproduce the illustrations on page 201 of The METAFONTbook

    mode_def medres = lowres_; pixels_per_inch:=600; enddef;

Thanks for trying. Too bad it didn't make a difference.

    row 57: 52+ 54- 33+ 35- |
    row 56: 55- 51+ 36- 32+ |
    row 55: 55- 51+ 36- 32+ |
    row 54: 55- 51+ 36- 32+ |
    row 53: 54- 50+ 35- 31+ |

    That is, the fourth row is the same as the second and third, not the fifth.

That's what I get too, with TL20 x86_64-linux (not surprisingly).

    Do different machines produce different results?

I believe the rasterization should be machine independent. I can't
imagine anything in the implementation (that is, web2c-specific) that
would have changed it, either.

    By the way, you mentioned that the printed illustration has no `*****'
    (five black pixels in a row) in the diagonal strokes. 

Not as far as I can tell. I haven't had a chance to buy a magnifying
glass, but I'm pretty sure.

    If the printed illustration has no `*****' it's better to drop the issue.

Well ... I think there is still a discrepancy worth reporting. In the
printed book, the fourth line is definitely the same as fifth, which is
not the results we are getting. I will check some more.

Thanks,
Karl
