I'm afraid I can't help you with that Haffi. I'm using Windows

I figured out and posted a patch to the Bugs list. No reply, but it appears that the patch was accepted and is now in the sources for 6.3.0-7.

Anthony: at that second URL is a page with "makegun.lif". It has 8 gliders which make a glider gun.

Another data point to ponder. The project's default configuration is to build a debug version. Changing it to a release version will produce an exe that does not crash.

I'm curious as to why you "can't post to magic-users" When I first got on the list I was blocked because my ISP's domain was in the SORBS database and imagemagick doesn't post messages from anyone who posts from a domain in SORBS. Actually, I haven't checked recently to see if they're still on ...

I found that if I convert a png to pct PSPX can read the resulting image so I had a look at why converting JPG to PCT caused a problem. It turns out that if the input image is a JPG then the pict coder uses JPG compression when it writes out the PCT and there appears to be a bug in this code ...

I've think I've found the problem with pict.c reported in http://redux.imagemagick.org/discussion-server/viewtopic.php?t=7875 As I mentioned in that thread, there's a difference between the way that pict.c writes the resolutions and the way that it reads them. The error appears to be in the way that ...

I don't know why it works but I have a workaround for the problem. I added some MessageBox statements to the configure.cpp code to try to find out where it was crashing and to my surprise the program started working! I wittled it down to just one additional MessageBox statement and configure still ...

I was going to try to sort out the problem with pict images as posted in http://redux.imagemagick.org/discussion-server/viewtopic.php?t=7875&highlight=pict I downloaded the windows source for 6.3.0-6 and built the configure program but when it is executed it crashes with an assertion failure as ...

That image didn't work for me. (I added a nice wide white border to it first) Are you sure it is correct?

I didn't test it but I copied it from http://en.wikipedia.org/wiki/Gun_(CA)

thank you for checking this out el_supremo You're welcome. I´ll have to wait till someone else fixes it... (If it will ever be done) The IM guys are very good at fixing up reported bugs and issuing a new release of the code, so if you can recompile from source you may have a fix in a few days. the ...

FWIW: I used the command line "convert" to convert a JPG, which "identify" says has a resolution of 300x300 dpi, to a PCT which identify says is 72x72 with undefined units. I've had a look at the pict.c coder and I think there are two problems. ReadPICTImage uses the ReadPixmap macro to read the x ...

> I'm using IM 6.0.6 - might that be relevant?

Yes. You would need 6.3.0. But it looks like Bonzo's method is much better anyway.

I wondered if a fx operator would work with a rule such as "If a pixel is white, change it to black if it has more than some threshold of black neighbours". I tested it by modifying the rules of the Game of Life as posted in http://redux.imagemagick.org/discussion-server/viewtopic.php?t=7683. The ...
