>> 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 'dialog' message to do this.<br>

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 '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.<br>
<br>Apple broke the event handling code used in GEM in 10.5. There is no fix other than 'write a full Cocoa app'. </div></div>
