Saving state for multiple calls

Jun 21, 2013 at 1:55 AM
I'm tracking my own pipeline state to reduce API calls.
I see that there is a way to get the DrawText call to restore state after it has finished.
However, if I have, say, 20 DrawText calls to make, is there a way to save the state before the first one, issue the 20 calls, then restore the state?

Thank you,

There's no public function for it in the interfaces, but if you use the source there's the CFW1StateSaver class that can save and restore the state. Combine with using the FW1_IMMEDIATECALL or the FW1_CONSTANTSPREPARED, FW1_BUFFERSPREPARED, and FW1_STATEPREPARED flags when calling DrawText to achieve that behavior.
