I'm trying to reduce the amount of memory a 3000x4000 jpeg image takes when shown full screen.
I'm not sure which method is better. Should I:
1. Create a separate, smaller thumbnail file and load that instead.
2. Just load the original jpeg using DecodePixelWidth
Are these are equivalent?
_fullResolutionBitmapImage = new BitmapImage();
_fullResolutionBitmapImage.ImageOpened += OnFullSizeImageOpened;
_fullResolutionBitmapImage.CreateOptions = BitmapCreateOptions.BackgroundCreation;
_fullResolutionBitmapImage.DecodePixelWidth = 480;
