TIFF files from pix_buffer (and others?) missing some "standard" tags?
by B. Bogart 06 Aug '10

06 Aug '10

Hey all, I've had trouble loading some TIFs generated in pd/Gem in PIL (python imaging). I asked on the list and it seems PIL expects some particular TIF tags being set in order to recognize the image. I think it can only be an improvement to add these tags so that tifs generated in pd/Gem can be loaded by as many applications as possible. The attachment contains the specific tags. Thanks, B. Bogart

model UV...
by sebastian pirch 07 Sep '09

07 Sep '09

hi IOhannes! in 1st place, THANKS for implementing this feature ;) you realy make me happy. i installed your experimental win build and it works great, when i add the gem directory to file/paths. only when i do so, pd crashes when i load a .mov using pix_film or pix_movie. when i remove the Gem path from file/paths again, pix_film and pix_movie work fine again, - but no more uv coordinates...is it a bug? or am i doing something wrong? im using pd extended 0.40.3 on winXP thanks for doing all this sebastian IOhannes m zmoelnig wrote: > hi. > > i have just added UV-texture support to [model]. > > now, UV-texcoords are automatically applied if present in the model > (with a fallback to the old-standard "linear" texmaps); you can manually > select UV-tex via [texture 2( (uÃ¤h) > > > > please test whether this change has broken something with the other > (linear/spheremap) texturing, esp. if you have additionally used > [pix_coordinates] > > fgmSDR > IOhannes -- www.3rd-eye.at Psssst!

pix_record issues with WinXp and Vista
by John Harrison 14 Apr '09

14 Apr '09

We are in the midst of our Pd/Gem module for our class and Gem is performing nicely on the students' varied OSes and machines. Our only real problem we have run into is that pix_record seems to be giving us some troubles on the WinXP and Vista machines. The results are not completely consistent amongst the machines but in general we especially have troubles trying to record especially from webcams. When trying to record from webcams we see messages in the Pd console like: recordQT: movie dimensions changed prev 320x61486 now 320x240 stopping recording error: recordQT : EndMediaEdits failed with error -2008 Some machines cannot record from the webcam but can record from other sources, such as pix_sig2pix. Some even fail with pix_sig2pix but do succeed in recording from pix_film as is done in the pix_record example patch included with Gem. Using the attached patch, a typical failure of pix_sig2pix looks like: recordQT: movie dimensions changed prev 0x0 now 640x480 stopping recording error: recordQT : EndMediaEdits failed with error -2008 This is with GEM ver 0.91-cvs compiled Apr 12, 2008, part of the latest Pd-extended 0-40.3 release for Windows. All the tested machines have the latest version of Quicktime (v7.6) installed. Thanks. -John

segfault resulting from conflicts with imageMagick
by B. Bogart 03 Mar '09

03 Mar '09

Hey all, I'm writing a gphoto2 interface object for PD. For some reason I get segfaults when running functions in my external, the backtrace shows these are related to libimageMagick. If I don't load Gem my code works as expected. I've attached the code. The openCam() causes the problem. Does anyone see anything in there that would conflict with imageMagick? Thanks, B. Bogart

openCV + Flext in XP (GEM-compatible)
by Jean-Yves Gratius 26 Feb '09

26 Feb '09

(sorry if double post) Hi here are my first steps in my attempt to writing a flext lib using openCV computervision library. Instead of writing new pix_objects or pdp_objects, the idea is to use an internal array of pointers pointing to opencv data structures and to pass indexes from one object to another. This way, it is possible to work on images but also on other data structures (like IplImage, cvSeg, cvPoint, etc... ) In this very first attempt, i wrote some externals in a flext lib : smooth-median, smooth-gaussian , dilate, erode, canny (contour detection), displaying window and a bridge from / to GEM pixes. You can have a look on source code and build for windows xp here <http://jy.gratius.free.fr/?q=node/167>. I don't intend to write a exhaustive library, only objects I need for my artistic purposes. But if you want to feedback / contribute, you are welcome... best, Jean-Yves

pix_filmQT vs pix_filmDarwin on OSX?
by IOhannes m zmoelnig 24 Feb '09

24 Feb '09

what's the difference between pix_filmQT and pix_filmDarwin on OSX? it seems like pix_filmQT cannot open movie-files (here), wherease pix_filmDarwin works just fine. can therefore pix_filmQT be removed entirely? (on w32, pix_film+filmQT is used successfully anyhow; i think pix_filmQT originally came from the w32 implementation) mfg.adsfr IOhannes

Memory usage on Linux
by B. Bogart 18 Feb '09

18 Feb '09

Hey all, I'm finally starting to get up my memory use. My patch now crashes when the machine gets up to 3GB (out of 4GB). I suppose this is due to the fact that this is a 32bit lenny machine, not 64bit. I'm running a custom kernel with the following related flags: # CONFIG_NOHIGHMEM is not set # CONFIG_HIGHMEM4G is not set CONFIG_HIGHMEM64G=y CONFIG_HIGHMEM=y free reports 4GB available (4148912 total). This is the first time I've gotten to the 3GB barrier. Is the only way to get access to all 4GB by installing a 64bit system? (Is it possible to "upgrade" from 32bit lenny to 64bit lenny?) Thanks for your help, B. Bogart
