WLUG meeting November 19th, 2020: Topic: Gamerzilla! Presenter: Dennis Payne

by Tim Keller

Hey Everybody! We've got a virtual meeting tomorrow Thursday November 19th, 2020. Long time WLUG member Dennis Payne will be giving a presentation on Gamerzilla. http://identicalsoftware.com/gamerzilla/index.html Time: 7PM Location: https://meet.jit.si/WlugMA As usual, expect the banter and usual delve into linux (or not!) related topics. I fully expect as usual it'll go late into the night. See ya there! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Re: CMYK jpeg

by Dennis Payne

Printing services generally want CMYK. Nothing I can do about that. I'm looking at using drivethrucards.com to print some cards. They have a beta service which takes CMYK jpeg that I thought I would use. If that doesn't work I could use Scribus. I loaded it but I decided not to try when it loaded a dialog at an insane size for some reason. (It had to be at least 4 times the width of my screen.) I'll give the imagemagik suggestion a try when I get a chance. If anyone wants to see a prototype card: https://social.freegamedev.net/photos/dulsi/image/6b4a87c2-eb26-4e0a-af26-e… The text has been slightly altered since then and the pentagon around the 12 was cleaned up.

Re: [EXT] Re: [EXT] CMYK jpeg

I can confirm that imagemagick will do the trick. If you’re using python, and want to do it within your program I’d recommend using PIL. from PIL import Image # image.mode is where the color space currently in use is stored X = Image.open(path) X.convert(‘cmyk’) From: "Krichevsky, Nicholas J. via WLUG" <wlug(a)lists.wlug.org> Reply-To: Worcester Linux Users' Group General Discussion <wlug(a)lists.wlug.org> Date: Sunday, November 15, 2020 at 5:57 PM To: Worcester Linux Users' Group General Discussion <wlug(a)lists.wlug.org> Cc: Dennis Payne <dulsi(a)identicalsoftware.com>, "Krichevsky, Nicholas J." <njkrichevsky(a)wpi.edu> Subject: [EXT] [WLUG] Re: [EXT] CMYK jpeg Looks like you can do this with imagemagick http://www.imagemagick.org/discourse-server/viewtopic.php?t=13359<https://nam03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.imagem…> converting RGB JPEGS to CMYK - ImageMagick<https://nam03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.imagem…> I need to convert a large number of images for my sister's ecommerce shop.

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.

Re: vagrant on debian 10 (buster) server

by John Stoffel

I can do a 'vagrant up' of a CentOS8 box, but it John> never finishes since it says it's just waiting for a network. 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
