Hmm, strange i had only warning but no error. I change 0 to 0.0 (to use float instead int in 'if ((color.g - colorToDiscard.g) <= 0.0)') and now i have no warning (i join the new .frag) : all works fine here. I think, the problem could come from the GPU (and so the version of GLSL supported ? I am not an expert in GLSL, so i can't answer correctly to this question :). Here i have a NVidia 9700M GTS (with the NVidia driver 180.44). ++ Jack Le jeudi 17 septembre 2009 à 12:43 +0200, Max a écrit : > hi jack, > > you are very welcome. most of the patches are heavily inspired by what > floats through the mailinglist or the help patches. > > i didn't have time to look into it but i am getting > > error: [glsl_fragment]: shader not loaded > linking: link 5.60519e-45 2.8026e-45 > linking: link 5.60519e-45 7.00649e-45 > [glsl_program]: Info_log: > [glsl_program]: ERROR: One or more attached shaders not successfully > compiled > > [glsl_program]: Link failed! > > with the shaders you've attached. are you shure they work on your > system? > > > Am 17.09.2009 um 01:39 schrieb Jack: > > > Hello Max, > > Thanx to share those useful patchs. > > Just one point, i have a problem with the color keying patch using > > GLSL, > > it doesn't work here (someone else ?).

Hi Jerome, i'm a free improviser using electric bass guitar, found/sound objects and C::NTR::L 1.2 a software developed in Pd with the help of the community. It recognizes which notes you play and trigger av fx with it.

convert number to pass it as argument to canvas

Be careful with that, as each different-looking number will eat a bit of RAM that will not come back. So, if you make a few million numbers, it'll eat all of your RAM. Also note that this is using %d, which chops off all fractional parts (rounding towards zero). There is %f, which instead shows most of the fractional part. It can also be configured to show various amounts of digits. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

YUV v/s RGBA
by Andres Ferrari 16 Sep '09

16 Sep '09

hello, i am trying to use pix_mask with 2 movies. the movies were encoded in RGBA colorspace (codec planarRGB) for .mov files. but when I open the video the pd console show that is not possible use pix_mask with 2 YUV movies... if I use open in pix_film (or pix_movie) with the argument RGBA...the pix_alpha works...but the quality is horible. the same happens with pix_alpha, pix_takealpha and pix_coloralpha. maybe this objects works only with still images in jpg?? maybe I need other codecs for my movies?? maybe I have to create the movie with his own alpha channel?? i don't know...please help me. (GEM 0.91 OSX 10.4 PPC) thanks a lot.

Re: [PD] new GUI screenshots

If you dislike vanilla appearance of Pd on Linux as much as I do, please try the pd.tk file I sent out sometime last week on this list and report any bugs. Hans has pointed a few that affect other platforms (this one was designed to provide minimal changes while making GUI more 21st century and without affecting Windows or OSX, apart from the few reported bugs) but other than that it appears rock solid here. Bear in mind that it does require tcl/tk 8.5 with antialiasing enabled. Best wishes, Ico
