I am trying to find out how to use FJCore to encode a WriteableBitmap to a jpeg. I understand that WriteableBitmap provides the raw pixels but I am not sure how to convert i
Sounds like [n] should be the byte-array of the image, I have been looking into encoding WriteableBitmap into a JPEG and found the same library but have not looked into it in detail, but assume this would be the case, will add more later to this answer to see if this works, as I have not have the chance to try it yet. There will be some method to get the bytes of a WritableBitmap in Silverlight I guess as it is possible to save to other types.
