question on writing GEM externals
by Sebastian Heymann 07 Jan '05

07 Jan '05

Hello, i am pretty new to PD and GEM but i love it and i want to use it form some project i am going to work on. so, lets get to the point. i have to write an external for PD which uses GEM to make some image processing. i managed to write a simple external for PD which was not very hard. but i could not yet get a GEM external up and running. i am working on macosx and windows. my latest work ended up in a lot of unresolved externals while PD is trying to load my external. i simply took the pix_blur class, changed it minimally and tried to compile it using the following lines: g++ -o pix_myblur.o -c pix_myblur.cpp -I../src g++ -bundle -undefined suppress -flat_namespace -o pix_myblur.pd_darwin pix_myblur.o running "./pd -lib Gem -lib pix_myblur" results in the following: dyld: ./pd Undefined symbols: __ZN11imageStruct5clearEv __ZN7GemBase11setModifiedEv __ZN7GemBase17obj_setupCallbackEP6_class __ZN7GemBase17realStopRenderingEv __ZN7GemBaseD2Ev __ZN9CPPExtern16setCPPObjectNameEPc __ZN9CPPExtern8m_holderE __ZN9GemPixObj10postrenderEP8GemState __ZN9GemPixObj12processImageER11imageStruct __ZN9GemPixObj14setPixModifiedEv __ZN9GemPixObj15processRGBImageER11imageStruct __ZN9GemPixObj17obj_setupCallbackEP6_class __ZN9GemPixObj6renderEP8GemState __ZN9GemPixObjC2Ev __ZTV9GemPixObj __ZnwmPvS_ Trace/BPT trap well, what did i forget? if somebody has a little makefile or hint, i would be very thankful. how can i load the Gem.pd_darwin symbols in my external, or do i have to do it? Thank you in advance. Sebastian

BUG: pix_snap flipped from pix_snap2tex on OSX
by B. Bogart 05 Jan '05

05 Jan '05

Just posted this on SF. When using pix_snap2tex everything seems to work as expected. When using pix_snap the buffer is flipped across the X axis. (top to bottom and bottom to top) Also pix_snap seems to set transparent alpha pixels in where the background of the buffer would be copied. I really like this bug, don't change it please! The X flipping is a pain when switching back and forth between snap and snap2tex. B>
