Re: cache exhausted

I'll add that I did try to upgrade to latest version, but there is no easy way without compiling from source and assembling together all delegates and stuff. (I've had much worse luck with that in the past)
I see a number of unanswered messages here how to install from rpm

Re: cache exhausted

Just using the stock version that came with the latest centos. .

I guess you changed the formatting of memory listings? I don't understand why GiB?

Thanks, I was afraid of that, as it breaks some other scripts I use.

Re: mitigating CVE-2018–16323

Interesting. I'm not sure why it's in the news then. Maybe it's because people have old versions installed still?

Anyway, I'll be banning that format as input.

Re: rotate zoom - broke after update

The added +repage after the rotate seems to have fixed it.

I've also tried this on IM 7.0.8, and it had the same problem. (Still trying to figure out what all else has changed with that update. )

Collage images with blend

Hi All,

I'm looking to do a 2x2 collage with overlapping / blended edges.

I can't figure out an easy way to do the overlap / blend part. Any suggestions?
