hi, sorry for crossposting this on pd-list and gem-dev. there is a bug in the current cvs version of gem, that was already solved in summer, but now it seems back... I uploaded screenshots from the gem alpha color bug here: http://www.parasitaere-kapazitaeten.net/Pd/Gem_bug! what can I do to fix that? marius.

Re: [GEM-dev] [PD] proper alpha channels in GEM?

I've made some tests with ubuntu, Gem displays the converted file with the alpha, no problems... In fact the problem come from the windows release of Gem (XP at least). All 0.91 dll versions crashes pd (both 0.39-3 and 0.41).I'll try soon to compile Gem.dll to have more info about that. The 0.90.1 snapshot doesn't display the tiff images made with convert, the image is well displayed only if I enable the alpha channel and disable other channels with photoshop (or gimp). Fortunately for me, my video server will run under linux in the long term, but it's unfair to not having the same abilities with both platforms.

Re: [GEM-dev] proper alpha channels in GEM?
by Patrice Colet 22 Oct '07

Hello, I've looked into pd-list archive and found this thread. Is it possible to load a picture with an alpha channel with pix_image? when I load such picture (both jpg and png) nothing happens (no console message), no image is loaded. My RGBA pictures are made with inkscape. +++++++++++++++++++++++++++++++++++++++++++++++++ message was: Subject: Re: proper alpha channels in GEM? List-id: the PureData - mailinglist <pd-list.iem.at> Yeah, I set the internal texture format in pix_texture to RGB instead of RGBA by mistake. I'm probably going to recompile the stuff for my page tonight and tomorrow, and I will post to the list when they are up. cgc At 4:31 PM -0500 11/29/03, doktorp wrote: Hi Ive been casually playing around with GEM and pix_image.

The image usually loads fine, but with no alpha. I am of course enabling alpha blending with the [alpha] object. any hints? thanks! -dok

Error messages with AVI
by hugo ramirez 14 Oct '07

14 Oct '07

Dear Gem developers. I have a problem with this error message: error: GEM: pix_film: Could not set palette: C:/Programme/pd/doc/examples/Gem/04.pix/../data/vp.avi GEM: pix_film: Loaded file: C:/Programme/pd/doc/examples/Gem/04.pix/../data/vp.avi with 225 frames (120x160) The thing is that I am running the Pd version 0.38.4-extended-RC8. When i try the film.pd example inside the examples/gem/pix, the homer.aviworks fine. But when i try my videos, even if they are compress an with the same size. PD crashes and i get the error message. I read that there is a problem with certain codecs. but I justed to have another machine, an IBM, now i have a Toshiba(both with Win XP), and i the old one even non compress video worked with the example. but in this "new" machine i doesnt work, maybe is the video card (ATI mobility radeon 64 MB). or is it somethimng else? Please help me in this one. with gratitud Hugo from Chile -- Hugo Ramirez

Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: problem with alpha channe Initial Comment: I am finding that gem is doing things very differently in two versions. The attached patch is slightly simplified from what I am running but the essence is running 3 versions of the same movie on 3 'screens' using [pix_threshold] and [pix_alpha] to selectively hide elements of the pictures at the front. This works fine when I use pd-extended0.38 When I try it with pd-extended0.39 (from http://at.or.at/hans/pd/installers.html ) it doesn't work. The pictures on the front 'screens' are all turned blueish but the selections aren't removed. I am running this on an intel Mac OSX10.4 I would be happy to stick with 0.38 but other things aren't working correctly with it, and I can't even run two versions in parallel because hans' version handles libraries internally, and gets confused when there is a preference file like the older version wants ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507079&aid=1809301&group_…
