tosymbol and tot crashes
by Johannes Burström 13 Jan '05

13 Jan '05

Hi list two issues: 1: a problem with tosymbol from cyclone, compiled this morning from cvs (with mingw on winxp, which now works without any makefile editing - thanks!). if i send it a message, pd simply crashes, as well as... 2: if i assign any of the other symbols besides '.' to an equally cvs-fresh [tot]. a version from 2003-04-18 (5th alpha) doesn't have this problem. if i had any programming skills, i might dig in to the sources, but as for now, i'm only able to make complaints from a safe distance... thanks! Johannes

Re: [PD-dev] API documentation
by Ian Smith-Heisters 13 Jan '05

13 Jan '05

I've done some looking around at automated documentation programs. There's HeaderDoc, which Hans-Christoph mentioned, AutoDoc, Doc++ and Doxygen. Of all of those I would go toward Doxygen, as it runs on Linux, Windows, and OSX and is GNU GPL, while HeaderDoc is APSL. Doxygen is used by KDevelop and Mozilla for their source documentation. I haven't seen anything that gives wiki ability out of the box, but it should be easy to add some sort of wiki comment system by means of links. The auto-generated docs act as a skeleton that is fleshed out with a wiki. I don't have a wiki server at my disposal, so I can't give an example of it, but Doxygen is very configurable and allows custom footers that could include links to a wiki via some sort of server side scripting. I've written a brief Doxygen config file and created documentation out of the 0.38 CVS HEAD src directory so you can get an idea of Doxygen. I did not alter the source files at all, so the commenting is *very* sparse. The Test: http://www.0x09.com/temp/doxydoc/html The only actual work I did to get the test: http://www.0x09.com/temp/doxydoc/ Doxygen help documentation http://www.0x09.com/temp/html === likage: === HeaderDoc http://developer.apple.com/darwin/projects/headerdoc/ Doc++ http://docpp.sourceforge.net/ Doxygen http://www.doxygen.org/ AutoDoc http://www.oche.de/~akupries/soft/autodoc/ Let me know all y'all's thoughts on it, and I'll see what I can set up so we can slowly start improving the documentation. Cheers, Ian

[Gem] Setting individual pixel alpha values?
by Andrew Johnston 13 Jan '05

13 Jan '05

Hi all, Please excuse this newbie question, but I'm somewhat stuck. I'd like to be able to set the alpha values of particular pixels in a picture somehow. The idea is to have a picture superimposed on top of a video and to be able to change the transparency of individual pixels in the still picture to reveal/conceal the video. I've looked at pix_set, but this requires a full list of all pixels in the picture. What I would like is to be able to specify the coordinates of a particular pixel and set its RGBA value. Seems like the reverse of pix_data I think. Perhaps there is a better method for achieving this effect? Any tips appreciated... Thanks, Andrew

alsa_seq patch compile error
by derek holzer 13 Jan '05

13 Jan '05

I'm trying to patch pd-0.38-0test10 with the alsa_seq support patch from CVS. I'm getting the following error: gcc -g -O2 -DPD -Wall -W -Wstrict-prototypes -Wno-unused -Wno-parentheses -Wno-switch -O6 -funroll-loops -fomit-frame-pointer -DDL_OPEN -DPA_USE_OSS -DPA_LITTLE_ENDIAN -DUNIX -DUNISTD -DUSEAPI_OSS -I../portaudio/pa_common -I../portaudio/pablio -I../portaudio/portmidi-macosx -fno-strict-aliasing -DPA_USE_ALSA -DUSEAPI_ALSA -DUSEAPI_JACK -DINSTALL_PREFIX=\"/usr/local\" -I. -c -o ../obj/s_audio_alsamm.o s_audio_alsamm.c make: *** No rule to make target `s_midi_alsa.c', needed by `s_midi_alsa.o'. Stop. I saw that the patch was made for pd-0.38-0test8. Has there been some major changes in the ALSA dept since then? Suggestions? derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 36: "Consult other sources -promising -unpromising"

crashes with pix_coordinate
by wolfgang schwarzenbrunner 12 Jan '05

12 Jan '05

hi... i m on xp using the latest gem release and figured out some troubles when using pix_coordinate. the task is a very simple one: i have a jpg (2x2 pixels in size) which are going to be multiplied with pix_coordinate on a cylinder. the strange thing is that sometimes it works perfect and sometimes pd crashes when i load the image with pix_image or any other image loading object (pix_film.....aso). all i can say is that it really must have something to do with pix_coordinate as the patch never crashes when i don`t use it.... love to get some hints regards wolfgang

I might just clarify that this happens when you're sending a list or multiple anythings, not with single anythings/floats/symbols. > 1: a problem with tosymbol from cyclone, compiled this morning from cvs > (with mingw on winxp, which now works without any makefile editing - > thanks!). if i send it a message, pd simply crashes, as well as... > Johannes --
