how to create .qtz file from custom cocoa app

2008-05-12 Thread Shashi Kumar
Hi All,
 I am a newb. I am looking for an cocoa app through which I can create 
.qtz file. The cocoa app will be having UI in which i 'll implement some 
effects on image. Now, lets say I 've a button export. When I 'll click export 
button, it should get saved as .qtz file. And I should be able to open it using 
quartz composer or 'll be able to render it in openGL.

 Can any one please tell, how this can be done ? It 'ld b kind if 
explain the approach step wise, if possible with some code.

with regards,
shashi.

That Cocoa app would be Quartz Composer. I don't believe there is any  
API that will allow you to create a .qtz file programmatically.

Is it not possible that from UI, I will generate XML file which  
will be kind of PList file of .qtz file containing tree list of its  
properties. And from that XML file we will create .qtz file ??


And, no, there isn't a Cocoa API that will effectively compile an  
XML file into a .qtz file. So as I said before, my understanding is  
that the only way you can create a .qtz file is by using the Quartz  
Composer application.
