> ViewNavigatorBase discards MultiDPIBitmapSource information for icon when
> saving and re-loading view data
> ---------------------------------------------------------------------------------------------------------
>
> Key: FLEX-33989
> URL: https://issues.apache.org/jira/browse/FLEX-33989
> Project: Apache Flex
> Issue Type: Bug
> Components: Mobile: ViewNavigator
> Affects Versions: Apache Flex 4.11.0
> Reporter: Vincent Spallek
> Assignee: Justin Mclean
> Labels: easyfix, easytest
>
> Steps to reproduce:
> - Create a TabbedViewNavigatorApplication with applicationDPI set to 160 dpi
> - Add a couple of ViewNavigator that have a MultiDPIBitmapSource as icon, and
> add icons for another resolution, e.g. 320 dpi
> - Run on a device with that higher resolution
> - Result: higher resolution icons will be loaded and displayed in the proper
> scale
> - Stop the application and reload it
> - Result: higher resolution icons will be loaded but not scaled properly, so
> they appear too large and with low resolution
> Root cause: ViewNavigatorBase discards the MultiDPIBitmapSource information
> in saveViewData() and instead only saves the high resolution bitmap. After
> re-loading in ViewNavigatorBase.loadViewData(), only the bitmap is restored
> without the DPI information. Hence, BitmapImage etc. don't have sufficient
> information to properly scale the image, see BitmapImage.measure()
