Re: [PD] Deken : Install externals with a list (Py Fave)
by Dan Wilcox 10 Apr '17

When the app needs a different version of the built in windows libs, that usually means it was build on a different version of Windows. Sometimes, you have to include a copy of the lib itself with the app and/or the user needs to install it. Hacky I know, but that’s what I’ve done in the past… IE: https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/7f5a39ee-e089… <https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/7f5a39ee-e089…> Often times, I’ve quickly had to go to one of these sites that hosts various Windows api dlls just to get something to work. Either that or copy it from another machine with an older OS. Seems like this might be an option for now. -------- Dan Wilcox @danomatika <https://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/> > On Jun 2, 2016, at 2:09 PM, pd-list-request(a)lists.iem.at wrote: > > From: rolfm(a)dds.nl <mailto:rolfm@dds.nl> > Subject: Re: [PD] Deken : Install externals with a list (Py Fave) > Date: June 2, 2016 at 2:09:31 PM MDT > To: pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at> > > > Roman wrote: > >> Just in case nobody more knowledgeable chimes in.

Finding a nearly full quadrilateral in a video frame
by Jean-Marie Adrien 10 Apr '17

10 Apr '17

(sorry for posting again / mail address & account micmac, hope i did not miss any answer !) Hello list I have to find for an installation the four corners of a bed (a rectangle) seen from above against the background (the floor), and this bed might slide a bit, so from time to time update the coordinates of the four corners. A person might be on the bed or close to it. So the general problem is find the coordinates x,y in the video frame (GEM) of a nearly perfect quadrilateral with a rather simple overall visual configuration Apparently, haarcascade techniques which work fantastically for face / hands (A.Villeret) seem inappropriate because the rectangle or quadrilateral is a too simple shape : anyone has a hint ? any object around ? blob ? lines - boundaries ?? Thanks a lot ! Jean-Marie

expr / expr~

quick questions... (1) these finally got a nice open license, like pd? (2) if they did, can all their functionality be properly documented in help files, etc?

[Gem] Modifying single pixel of pix image
by Roman Haefeli 09 Apr '17

09 Apr '17

Hi Is it possible to manipulate a single pixel of a an image loaded by [pix_image]? Specifically, I'd like to change the alpha value of certain pixels. It doesn't matter to me whether the manipulation happens in the pix realm or the GL realm. Currently I can think only of cumbersome ways like using [pix_dump] -> [pix_set] and applying the manipulation to the largish list passed between them. Or by using [pix_pix2sig~] -> [pix_sig2pix~] which is basically the same, but would allow to do the manipulation on a table. Roman

Re: [PD] refresh MIDI device list on run
by mario.buoninfante 09 Apr '17

09 Apr '17

What I noticed on Win10 is that if the device is connected when you launch Pd, then you can unplug it and plug it again, without any issues. And one thing more, a new device is detected only if I've never opened the MIDI dialog. I mean: 1. Launch Pd 2. Plug a MIDI device 3. Open MIDI dialog (either from Menu or within the patch) 4. Pd recognize the device After I opened MIDI dialog the first time, no new devices will be recognized.

refresh MIDI device list on run

Hi all, does anyone know if it's possible to "refresh" the MIDI device list while Pd is running? i.e. you plug a new device on run. Cheers, Mario

New deken feature, create system user folder (was how-do-i-install-externals-and-help-files page (was Re: Linux Global folder for externals)
by Alexandre Torres Porres 08 Apr '17

08 Apr '17

thought we'd finally change the thread name... for those who are getting there now, this is the discussion about a new deken feature, that would suggest to download to the system user folder and then create it if it's not there. I was testing the new version and it didn't work. 2017-03-04 6:30 GMT-03:00 Roman Haefeli <reduzent(a)gmail.com>: > > But why did it not create the folder /Users/alex/Library/Pd (...)? It actually didn't suggest to write to ~/Library/Pd, which needed to happen first, the creation of the folder would be the next step. > you have admin rights on your Mac and you can write into XX.app folders > (...) Deken looks through search paths and finds one that is writable, thus > it does not suggest to install to /Users/alex/Library/Pd. Can we close this thread with 'works as designed'? I thought the design was to suggest to write into the ~/Library/Pd folder, and then create it. This is not what's happening! It only suggests it if it didn't find any folder it can use. In the end, there is no difference for me. So, for it to suggest to download to ~/Library/Pd, I have to first create that folder myself, and the whole discussion here seemed to be the need to create that folder automatically, to make things easier for the user. cheers
