If I start off using a bitmap, and all of a sudden start using jpeg, 
will it automagically work or does one have to initiate the jpeg in some 

Example: you start off working with a classic BMP, but then 60 lines of 
code later you want to work with it as a jpeg. Do you just magically 
start working with a jpeg without any worry, or you have to take some 

Likely, this is explained in a article on the wiki somewhere, I don't 
know :-)
