Re: Using flters inside a .qtz

Is it possible to use the filters inside a .qtz file without rendering
(no use of QCRenderer renderAtTime:) ?

What I'd like to have is a sequence of filters in a .qtz, lets say
Gaussian, followed by (connected to the input of) Sepia, publishing
the first filter input and last filter output. Then open the .qtz as a
QCRenderer and feed the first filter a CIImage and get the output
CIImage for rendering with CIContext's drawImage:

You need to render at least one frame in the QCRenderer just to "execute" the composition and produce outputs.

The QCRenderer will use CIImages internally but output a NSImage for compatibility with AppKit, which might be inefficient in your case when converting back to a CIImage.

What exactly are you trying to achieve?
