Correct fade transition when content modes differ#786
Merged
Conversation
Previously runCrossDissolveWithContentMode was adding the transitionView to the imageView and settting the imageViews alpha to 0. This resulted in the image immediately disappearing since alpha of subviews are multiplied by the alpha of parent views.

An alternative to trying to match any masking of imageView is to take a snapshot of the view before it is changed. This branch does that alternative method: main...ejensen:transition-fix-2

Thanks for fixing it!
I don't have any strong preferences in terms of which approach to use. I assume the one from the PR was your primary choice, so I'm OK merging it as is.

runCrossDissolveWithContentModewas adding thetransitionViewas a subview of theimageViewand setttingimageView.alpha = 0. This resulted in the image immediately disappearing since thealphaof subviews is multiplied by thealphaof super views.This PR adds the
transitionViewto thesuperviewof theimageViewso the two image view's alphas are independent and properly cross-dissolve.
