Supposedly it is part of the JPEG spec, but I haven't seen anyone other than Apple use it. It is kind of like having a TIFF with run-length JPEG compression. > also on my machine mac osx 10.6.2 GEM: ver: 0.92.2 compiled: Dec 17 2009 > Gem stop rendering confirm the dialog to pix_record > after start rendering again 2 sec later it stop again > then start again it´s ok and use the changes of the dialog > > The dialog always stopped rendering because the event loop waits for the dialog to close. You will notice that GEM creates a 'pd' app in the Dock in order to do things like window management. Command line apps in OSX cannot just open windows without being a GUI app. It is a hack. Apple broke the event handling code used in GEM in 10.5. There is no fix other than 'write a full Cocoa app'.
