&gt;&gt; Setting the quality for Photo-JPEG to 100% changes it from YUV to lossless ARGB compression.  You can keep the alpha and avoid colorspace conversion.  Use the &#39;dialog&#39; message to do this.<br>

also on my machine mac osx 10.6.2 GEM: ver: 0.92.2 compiled: Dec 17 2009<br></div>
Gem stop rendering confirm the dialog to pix_record<br>
after start rendering again 2 sec later it stop again<br>
then start again it´s ok and use the changes of the dialog<br>
<font color="#888888"></font><br></blockquote><div><font color="#888888"></font> <br>The dialog always stopped rendering because the event loop waits for the dialog to close.  You will notice that GEM creates a &#39;pd&#39; 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.<br>
<br>Apple broke the event handling code used in GEM in 10.5.  There is no fix other than &#39;write a full Cocoa app&#39;.  </div></div>
