Hi I am developing a simple video player that has to be able to allow the user to zoom in/out the played video, to "pan" the video's 'viewport' with the mouse when the video has been zoomed in and doesn't fit completely on the view, and allow to flip the played movie upside down.
It seems Core Animation is the way to go. I am still not exactly sure how to implement this (I managed to get the QTMovieLayer displayed, and get it zoomed and panned by adjusting the layer's frame (reacting on NSView's events), but still there is a lot to do - I need to make sure the QTMovieLayer can't be scrolled out of the "movie zone" for example, and the layer doesn't slip away when being zoomed out too much). I am wondering if there's a simpler way to implement what i am doing. I was reading about CAScrollLayer and CATiledLayer - might those help me? Should I use affine transformations? Or these layer.frame operations are the way to go? I am a newbie in Core Animation, and I would really appreciate a good advice about what is the correct way to do what I am trying to do :-) Thanks! _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
