Dennis> Thanks for everyone listening to my talk. Been putting Dennis> together changes to make the presentation better. And a big thank you for putting up with my comments! I hope you took them in the spirit they were offered, and not me being a jerk. I'm not a programmer, but as a long time sysadmin who's worked on compiling various programs over the years and tweaking them to work, I think I have a decent idea of good APIs.... at least I like to think so! :-) Cheers, John

Re: Sharing Screens and jitsi

by Dennis Payne

The organizers of MiniDebConf Online informed me of a feature of jitsi. When you share your screen, it stops your video. That's why I used guvcview to show my video during the presentation. Apparently if you just click the video button again, it starts showing you in the bottom right corner. The presenter can't see it unless they have two displays and jitsi showing on a non shared screen. -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

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

by Killea, Ryan B.

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.
