Perhaps you misunderstood the purpose of the tutorial. This is to show you how 
images can be generated automatically on demand from the user and cached by 
Magnolia, so even tho you allow say 7 different variations, they will be 
generated only and only if at least one user requests them, thus saving you 
extra processing in case nobody ever looks at given variation of the image.

Using the API directly is perhaps what you really want.

Perhaps your images had originally transparent background and after 
transformations they don't and background is filled with some default value?

Without seeing the original image and the whole set of operations with their 
exact params it is very unlikely that anyone would be able to give you solution 
to that problem.
