Please give a brief summary of your issue:
I cannot seem to find a way to get ViewChangeCollection to pass on to the RefreshAndUpdate function.
Please describe your issue and provide steps to reproduce it:
I am facing troubles with getting the WPF-viewer to update all annotations added. We enroll a lot of square annotations which should then be refreshed/updated on the viewer. However, we have tried to call Update(annottation, pagenumber) for each push of annotation, and/or Update(true) at the end. Everytime, randomly some of the annotations are not updated in the viewer, they are however selectable.
Thus, we would like to test out the RefreshAndUpdate() function, however, it seems not explained how to build a ViewChangeCollection.
