PCL: Realtime Preview

[georg.viehoever]

I am looking for a good example on how to implement a realtime preview.

- I see it is implemented for instance in the Binarize process. Is this an implementation template that I should follow? Which process that is avaiable in source could I study?

- The PCL documentation says: "The Real-Time Preview system is undergoing extensive development in PixInsight. Be aware that this class will be updated and enhanced considerably in future PCL Releases". Which features should I try to avoid? Which can I rely on?

- Which classes should I study? pcl::RealTimePreview is important. ProcessInstance::*Realtime* as well. What else?

- Any additional documentation on RealTimePreview and ProcessInstance (and maybe other classes) interact would be welcome.

Hi Georg,

Yes, Binarize has a good real time preview implementation. CurvesTransformation is another good example. Note that real-time renditions are now being generated in a background thread (RealTimeThread) when possible, which improves GUI responsiveness.

Which features should I try to avoid? Which can I rely on?

Given the immense workload that I have currently, the R-T preview will remain unchanged for a long, long time. We have many priorities before making a significant improvement to this feature. Just use CurvesTransformation as a good example for your implementation.
