Thanks, now I got it :-)

I got this too, now, so it seems like the stubs-thing was
fixed in this 0.46 :-)

Yes, the extension seems to work in principle, but it seems
like graphicsmagick dropped the "-copy" feature from "convert",
which I'd have had good use for...   Also I got it into seg-
faults a couple of times, as well, but maybe my commands were
just bad.

Querying "pixels" just didn't do anything visible with an
empty "map"-argument, and segfaulted with whatever else I
tried for that argument.  Maybe I read the docs not well enough..

My current solution involves "-copy" to copy certain "far-off"
parts of the image into a more central part, then only convert
the smaller region around the central parts to bmp3 format.

I might try this TclMagick 0.46 with original imagemagick,
to see if that gives me a "copy" subcommand for $wand.

And I've yet to study the docs better to see how "pixel" is
really to be used.

Thanks 2 all!
