I would, however, bring it line with the `else` clause - either both use `wimg = methodName(..., wimg, ...);` or just `methodName(..., wimg, ...);`. This is fine since the input `WritableImage` is never `null`. From a readability point of view, using return values seems better.

I also don't have a strong opinion, so I'm OK with you leaving it as-is.
