Every document contains a bug-description and also a shortdescription, how to serve the app and version-information s in the appendix of the document. The name of the project/app is matrixguide. The app Matrixguide is based on the template Blank App ( Shared) I have taken much effort to describe the bug(s) as good and easy as possible. Don t scare about the document has so many pages: Normally you only have to read chapter 1 and chapter 2. To investigate/comprehend a bug: Install the project from the link in the mail I sent to bugzilla@xamarin.com Read chapter 2 Bug description If you have problems to serve the app: Read the Chapter How to serve the app (in the appendix of this document) For Version information s: Read the chapter Version-Information s (at the end of this document If you need further information s.

3 Scroll down (until the images are shown): As you can see: the Image itself is scaled correct (and also in the correct aspect-ratio) but there is way to much blank space over and under the images ( 1 ) and ( 2 ) The original image-size is 365 (Height) and 550 (Width). So the size-requests are settled corresponding: HeightRequest = 365, WidthRequest = 550, If the orientation of the iphone is changed from portrait- to landscape-orientation, the image is scaled correct and the Iphone shows the images without blank space over and under the image. So I think, the rendering-size is not calculated correct: It seems as, if the WidthRequest is greater than the available space on the page: The real width to render the image is calculated correct, but not the height (maybe is not recalculated ans stay how defined in HeightRequest) MATRIX Solutions AG Autor: Fredy Wenger Stand vom Seite 3 / 16
