MKIV and externaligure inside metafun

MKIV and externaligure inside metafun

[Mojca Miklavec]

Hello Hans,

nothing urgent (I'm still on MKII), but it seems that MKIV (maybe only
on my machine?) has problems with
    externalfigure("filename.png")

OK, so it's again "my computer only" problem :) :) :)

Well, never mind then. If it works for you then it probably works on
at least a few more machines, or will start working with the next
major release at least. Thanks a lot for looking into it.

(I used the "thought-it-was-working" installation this time, not with
the old and broken one.)

I remember similar problem a while ago due to some transparency being
used on the same page (but at that time you said it was a bug in adobe
reader).

Thank you,
    Mojca

On my machine

\startMPcode
externalfigure("filename.png");
\stopMPcode

doesn't work in MKIV at all. On Hans' machine it generates weird
colors (though not that much wrong). I can send you an example, but I
guess that it behaves the same way with any png image.

But I would not worry too much. My installation is always broken when
it works for everyone else :) :) :)

ah, so now er're talking of mp code

i bet it works, but that you don't see the small image ...

\startMPcode
externalfigure("filename.png") scaled 10cm ;
\stopMPcode

(actually in mkiv i could default to the natural size)

I guess that I give up.

It started working now for no particular reason (no change in files,
no change in my installation).

And the colors are fine as well.

My only explanation is that I had a broken png file at some moment and
even if I tried to proccess it again, luatex still thought that png
was broken (maybe luatex caches images somewhere?).

My only explanation: Hans has direct access to your harddisk and changes 
things silently in the background.... :D

ok, this was supposed to be a secret, but indeed taco and i can log into 
her time capsule device and move her back- and forward in time depending 
on how much we mess up luatex; unfortunately we could not foresee that 
it would broke her beloved mac

(maybe we should start a 'new laptop for mojca project')

The "project" has already been successful. Apple will send me a free
replacement as soon as I come to Germany (Slovenia is not listed on
their World map).

As as consequence someone else will have to start providing Mac ppc
binaries next month since their new OS most probably doesn't support
cross-compiling for ppc any more.
