available formats and params for Image.save()

[News123]

Thanks a lot Gabriel,

Your answer is perfect.

I was only looking in part II of the PIL manual and overlooked the
Appendix :-(.

I also apreciate
Image.ID , Image.SAVE , Image.OPEN

I saw them when typing
dir Image
but I never had the idea of calling Image.init() first

bye
