Re: [EXT] CMYK jpeg

by Krichevsky, Nicholas J.

Looks like you can do this with imagemagick http://www.imagemagick.org/discourse-server/viewtopic.php?t=13359 converting RGB JPEGS to CMYK - ImageMagick<http://www.imagemagick.org/discourse-server/viewtopic.php?t=13359> I need to convert a large number of images for my sister's ecommerce shop. Her website automatically handles images provided they are in the CMYK version of JPEG, but not the RGB version, and provided the starting file size is less than 1MB. www.imagemagick.org ________________________________ From: Dennis Payne via WLUG <wlug(a)lists.wlug.org> Sent: Sunday, November 15, 2020 8:22 PM To: Worcester Linux Users' Group General Discussion <wlug(a)lists.wlug.org> Cc: Dennis Payne <dulsi(a)identicalsoftware.com> Subject: [EXT] [WLUG] CMYK jpeg Anybody know of an easy tool to convert an image into a CMYK color space jpeg?

Re: CMYK jpeg

by Logan Brown

CMYK encoded jpegs are technically within spec ( https://www.itu.int/rec/T-REC-T.872-201206-I/en) but are exceedingly uncommon and support is pretty sporatic. Typically a JPEG contains RGB data encoded as YCbCr. If your application strictly requires CMYK data, you probably want to consider another file format.

Ok, just to give some more details, I've got vagrant working now on my main desktop box, and I think the problem is that I already have a libvirt install on my server, with a Bridged Network setup. So having a bridge setup confuses Vagrant and how it needs to be setup. Haven't gotten it working yet, but I have a better idea of where to look. John

If we're still using Jitsi, is there a good place to test it out ahead of time?

Hey Everybody! NO MEETING TOMORROW! Meeting next Thursday (11/19/2020)

by Tim Keller

Our next WLUG meeting is Nov 19th, 2020. I've pushed the meeting out a week because I have a prior engagement and frankly this second Thursday snuck up on me. As an aside, are people happy with the Thursday meeting or would a different day in the week work better for people? I'll let you know more details when I get them. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

vagrant on debian 10 (buster) server

by John Stoffel

Guys, Has anyone played with vagrant on Debian Buster using libvirt as the provider? I can do a 'vagrant up' of a CentOS8 box, but it never finishes since it says it's just waiting for a network. But I have a virbr1 running with 192.168.121.0/24 subnet, and I can ping the new vagrant box at 192.168.121.18 without a problem. I can even fire up a VNC viewer and connect to the console and see that it's up and it's gotten an IP address. All I'm doing is: mkdir /scatch/vagrant vagrant box add centos/7 --provider=libvirt vagrant box add centos/8 --provider=libvirt cd /scratch/vagrant mkdir centos8 cd centos8 vagrant init centos/8 vagrant up I've got dnsmasq running on my server, and it looks to be giving out IPs on that subnet properly. Stupid VM just sits at: root@quad:/scratch/vagrant/centos8# vagrant reload ==> default: Halting domain... ==> default: Starting domain. ==> default: Waiting for domain to get an IP address... And then nothing. The console is fine, I can VNC into it and login as the root user with the password of 'vagrant' and see that the network is up, etc. Going nuts trying to make this work. John
