create tile data in background agent wp7

Question

What's a good way to create the bitmap needed to update a live tile in a background agent? In the UI thread, you use writeableBitmap class, but this does not work in the non-ui thread. There are many examples of tiles in background agent, but they all use bitmaps formerly created in the UI. Any ideas? Thanks.

There are 3 ways a live tile can be customized. The text, a count in the top right or by changing the background image. Is the third what you want? — cjds, Jan 16 '13 at 00:59

WriteableBitmap doesn't need UI, it merely needs a Dispatcher. Background agents have it.

See this answer for sample.
