I test Gem 0.91-3 and pd 0.41-4 with the same OS pix_video works perfectly. Otherwise I have a strange message in the pd console when the Gem library is loaded in pd 0.42-4 : warning: old method 'width' for class 'curve' renamed 'width_aliased' warning: old method 'draw' for class 'curve' renamed 'draw_aliased' warning: old method 'draw' for class 'curve3d' renamed 'draw_aliased' warning: old method 'open' for class 'fragment_program' renamed 'open_aliased' warning: old method 'print' for class 'fragment_program' renamed 'print_aliased' warning: old method 'open' for class 'glsl_fragment' renamed 'open_aliased' warning: old method 'print' for class 'glsl_fragment' renamed 'print_aliased' warning: old method 'gem_state' for class 'pix_filmDarwin' renamed 'gem_state_aliased' warning: old method 'open' for class 'pix_filmDarwin' renamed 'open_aliased' warning: old method 'img_num' for class 'pix_filmDarwin' renamed 'img_num_aliased' warning: old method 'auto' for class 'pix_filmDarwin' renamed 'auto_aliased' warning: class 'pix_film' overwritten\; old one renamed 'pix_film_aliased' warning: old method 'gem_state' for class 'pix_filmQT' renamed 'gem_state_aliased' warning: old method 'open' for class 'pix_filmQT' renamed 'open_aliased' warning: old method 'img_num' for class 'pix_filmQT' renamed 'img_num_aliased' warning: old method 'auto' for class 'pix_filmQT' renamed 'auto_aliased' warning: old method 'gem_state' for class 'pix_videoDarwin' renamed 'gem_state_aliased' warning: old method 'dialog' for class 'pix_videoDarwin' renamed 'dialog_aliased' warning: old method 'colorspace' for class 'pix_videoDarwin' renamed 'colorspace_aliased' warning: class 'pix_video' overwritten\; old one renamed 'pix_video_aliased' warning: old method 'width' for class 'polygon' renamed 'width_aliased' warning: old method 'draw' for class 'polygon' renamed 'draw_aliased' warning: old method 'draw' for class 'primTri' renamed 'draw_aliased' warning: old method 'width' for class 'scopeXYZ' renamed 'width_aliased' warning: old method 'draw' for class 'scopeXYZ' renamed 'draw_aliased' GEM: Graphics Environment for Multimedia GEM: ver: 0.91.3 'tigital' GEM: compiled: Mar 25 2009 GEM: maintained by IOhannes m zmoelnig GEM: Authors : Mark Danks (original version) GEM: Chris Clepper GEM: James Tittle GEM: IOhannes m zmoelnig GEM: with help by Guenter Geiger, Daniel Heckenberg, Cyrille Henry, et al.

Category: None Group: None >Status: Pending >Resolution: Works For Me Priority: 5 Private: No Submitted By: ClaudiusMaximus (claudiusmaximus) Assigned to: Nobody/Anonymous (nobody) Summary: pix_write aborts pd when disk is full Initial Comment: If you fill the disk with pix_write (quite easy when saving in TIFF format), pd aborts. error: ImageMagick: /mnt/wednesday/in/rec/img60413.tif: Write error at scanline 456. `TIFFAppendToStrip' pd: magick/exception.c:932: ThrowMagickExceptionList: Assertion `exception->signature == 0xabacadabUL' failed. (then pd aborts) A fix would ideally let the pd patch know something went wrong so it could turn off image saving or quit by itself or whatever it wants to do. Versions: Gem-0.91.1-2 and pd-0.41.4 from the pure:dyne repository. ---------------------------------------------------------------------- >Comment By: IOhannes m zmlnig (zmoelnig) Date: 2009-06-02 10:27 Message: hmm, unable to reproduce this. when my disk fills up i get: > error: ImageMagick: /home/zmoelnig/tmp/pixes/delme00117.tif: Write error at scanline 21. `TIFFAppendToStrip' > error: GEM: Unable to save image to '/home/zmoelnig/tmp/pixes/delme00117.tif' (and i get a number of empty files from then on.) the graceful errorhandling of magick-exceptions should be in any 0.91 release. as for the feedback to the patch, i am not sure how to really handle this in a simple way yet (e.g. without adding a "state" outlet to each and every object - but then: why not?) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507079&aid=2782081&group_…
