| Anthony, I've spent the better part of a day and night tracing

|
| Im-3.2.5 give _very_ different results for
|
| convert -depth 8 -sharpen '0.0x0.5' in.png out.png
|
| than the exact same command in Im-3.3.4
|
| Recall I switched to the latter because Cristy was kind enough to fix
| the behaviour of display when stretching the display window and when
| using the magnifier.
|
| Im-3.3.4 gives a much sharper result then 3.2.5 (and hence breaks
| some things badly). Furthermore, with Im-3.2.5 the
| differences between 0.0x0.2, 0.0x0.5, 0.0x1.0 are quite obvious.
|
| With Im-3.3.4 there is nearly no difference. So it starts out much
| sharper and the adjustability is much poorer if one wants to enhance
| by only a very small amount.
|
| Do you know what's going on?
| Were there changes from 3.2.5 to 3.3.4 that would have done this?
|
| I am "regressing" back to 3.2.5 to regenerate some results for a
| report that I must send tomorrow. It's 3am now!

I am not sure.

* Add -adaptive-sharpen to the convert and mogrify programs.
This probably should not have effected sharpen. Prehaps you better
try putting up some examples.
Especially into the IM Forum bugs area.
Though I am sorry I have not been reading the forum as much and normal
of late as I am very bust with work commitments right now.
