The Windows Phone 7 apps name is 3D Poly Fun. You can download the free version which has all the features as the paid version with ads. This is a 3D photo application with interesting geometries. 18 different
polyhedra can be used to animate pictures and colors. The polyhedron can be animated by opening or closing them as well as rotating them. The polyhedra can show custom colors, pictures from media library. I used the Writeablebitmapex to
create user selection color rectangles on the fly. The Writeablebitmapex enabled me to save the user selected color rectangles in the isolated storage. In this app instead of using the whole library I used snippets from the source code.
I am also developing another application ( which I have not named yet) where I will be using many more features of the Writeablebitmapex windows phone 7 binary. In this app I will be using the clone, gradient (which we discussed in the post), transforms
and other features. I will post a note here when it is ready.
I think the major strength of the Writeablebitmapex is how fast I could use it without knowing too much about the internal workings.
I have a suggestion to make. It was little bit difficult for me to dig through to find the Windows Phone 7 binary. A more easy way to do this with some documentation might be useful.
Again I have to complement you and your team for excellent work which has simplified and enhanced my coding life.
