I've got the code working on the Main Thread, but now the tricky
bit because since I am using
UIGraphicsBeginImageContextWithOptions and
UIGraphicsEndImageContext in order to capture the Image, and, as
far as I know these methods can only be called on the Main Thread.
Is this correct?
No, these methods are fine as long as you use the context only
within the same invocation (that is, don't try to share the context
between threads or split the begin/end between threads).
Really? Just double checking you mean what you mean. My code basicall
UIGraphicsBeginImageContextWithOptions
UIGraphicsGetCurrentContext
---Reander PDF Page into the Context obtained above.
UIGraphicsGetImageFromCurrentImageContext
UIGraphicsEndImageContext
This is all in one method that runs in one thread, are you saying
this will work ok?
Thanks a lot for your help.
Dave
