Quartz compositions created in Snow Leopard (10.6) doesn't work in Leopard (10.5) despite testing in
- by adib
Hi
I have a reasonably advanced (many patches and subpatches) quartz composition that was created in Snow Leopard but doesn't run well (many elements are not rendered) in Leopard. The composition tested OK via Quartz Composer's Test in Runtime option and works fine for both Leopard 32-bits and Leopard 64-bits (menu item "File | Test in Runtime | Leopard 32-bits".
In an actual Leopard (32-bits) system, a lot of elements are not rendered in the quartz composition. Below are the log file excerpt when the composition is run in QuickTime Player under Leopard:
QuickTime Player[134] *** <QCNodeManager | namespace = "com.apple.QuartzComposer" | 335 nodes>: Patch with name "/units to pixels" is missing
QuickTime Player[134] *** Message from <QCPatch = 0x06D82880 "(null)">:Cannot create node of class "/units to pixels" and identifier "(null)"
QuickTime Player[134] *** Message from <QCPatch = 0x06D7C130 "(null)">:Cannot create node of class "/resize image to target" and identifier "(null)"
QuickTime Player[134] *** Message from <QCPatch = 0x06D7C130 "(null)">:Cannot create connection from ["outputValue" @ "Math_1"] to ["Target_Pixels" @ "Patch_2"]
The patch "units to pixels" is a system patch in Snow Leopard whereas the patch "resize image to target" is a custom virtual patch located in my home directory.
It seems that we can cross out problems in which the composition is referencing a missing virtual patch. I have tested the composition under another user's account and it ran fine which shows that it already embeds the "resize image to target" virtual patch that is located in my home directory.
I'm really puzzled why the composition passes the Leopard Runtime test but yet fail to run in an actual Leopard OS? Is there a post-processing step that I need to run to the composition file? Is there any way to make this patch more compatible with Leopard?
Thanks in advance.
