I’d like to append a border (20px white) to an image, save as a new jpeg image (orginal image with a border), I don’t know how do I start. Can anyone give me a direction or code example?
Thanks

You have two ways to do it:
On your UI, wrap the image with a Border element with the correct settings and use
new WriteableBitmap(borderElement, null)to create a new WriteableBitmap which you can then save using the SaveJpeg extension method.Your other option is to use the WriteableBitmapEx class library to graphically add the graphical elements you want.
I’ve used both. The advantages for (1) is that there’s less hassle in the sense of adding a dependeny on another DLL. The advantage in (2) is that you don’t need to mess with your UI to create the image.
