The Featured Discussion Board Post this week is Image view undesirably cropped started by m.findlay93

m.findlay93 is trying to implement an Image View within a page for a Windows Phone application, but when it is deployed, the image gets cropped. He states his problem and provides a screen grab of the issue faced.

Ratish Philip admits to facing the same problem. When he removes CacheMode="BitmapCache", the cropping goes away but the zoom and pan performance is affected. He suspects a size limit to the image and recommends taking a look at the PhotoPage.xaml in the FilterExplorer project on the Nokia Developer Github repository.

Lee McPherson confirms that the size limit does exist. In WP7 it is 2048x2048 and 4096x4096 in WP8. He suggests loading the image using DecodePixenHeight or DecodePixelWidth to reduce the resolution. The drawback of this approach is that one would lose some resolution on zooming. The alternate and cleaner solution would be to use the Nokia Imaging SDK and follow articles in the Nokia Developer Wiki that explain how to display high resolution images.

This discussion was selected for featuring because it highlights how it is possible to work around API limitations by using Nokia Imaging SDK for high resolution pictures.
