doug> I have a topic idea and/OR question-for-list-here+now, but only half a clue; I seek the Grail (our group's collective mind meld) on.... Resizing/cropping images efficiently w/r/t ( a) my time to perform the file manipuation, and (b) efficient+good JPG compression/filesize-shrinking. In my nearly-abandoned Windows-OS world, I had/have an obscure tool ACDSee which I paid $10-20 for, 25 yrs ago ! (still avail for windows only) which.... --- is very easy/quick to use in my opinion --- does an easy image rotation if needed --- does an easy crop-and-save (the main feature for me) --- magically, without asking about quality/compression? DOES COMPRESS Very Well: .... I can crop most images (eg typical smartphone jpg around 4mb for example, ........ I can crop most of it and save with a typical result = 10-20% of original file size = 400-800k ........... and you wouldn't believe how good the 10%-smaller image tends to look. GIMP can do these, except seems to lack the magical quality of ACDSee for a downsize. while doing GIMP's Crop first, then Export to JPG, GIMP Export asks for a QUALITY in the 1-100% range, if I choose 10% I do get a 400k file, but it's grainy as you might expect, and I wonder how ACDSee does such superior compression with barely any loss/grainy result. -------doug

Re: Best place to look for webcam drivers

I'd probably spin up an old version of Linux which had that driver and see how it works on there. But in reality I'd probably dump it if it's not supported. Just looking on the web I see that Creative hasn't really released any updated drivers. But... looking also on the Linux Kernel 5.3 page, it looks like this might still be supported. https://linuxtv.org/downloads/v4l-dvb-apis/v4l-drivers/gspca-cardlist.html Can you show the output of 'lsusb' when it's hooked into your system? And what exact version of Mint are you running? Install the v4l-utils package and then do: v4l2-ctl --list-devices once you have the USB camera installed and see what it says. John

Next Meeting moved to August 15th 2019

by Tim Keller

Hey Gang, I'm going to move the meeting to August 15th. If you've got a topic idea, let me know. Otherwise, we can either do an open topic meeting. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Best place to look for webcam drivers

by Richard Klein

I picked up a Creative Labs model VF0250 webcam, but V4L isn't detecting any devices. I googled it and it looks like gspca supported this model, but it also looks like gspca was abandoned years ago. Where would you look for answers? BTW, this is for Mint.
