+1

Regarding your commit, there are more places to check the alpha value on the SubstanceImageCreator class.

Thanks! The single fix that I did in my fork was enough to eliminate the problem in our project, but you may be correct that this problem can occur in other instances.

@enwired do you have an scenario for this same issue on https://github.com/kirill-grouchnikov/substance/pull/18? (in order to find the root cause)

Unfortunately I do not have any way to reproduce this. It was seen once or twice in our code, but was not easily reproducible. It has never been seen again after I applied the little fix.
