[Gimp-user] Setting preferences for saving png

[Pere Pujal i Carabantes]

Hi all!

I usually have to save transparent pixels of PNGs, but time to time
don't save them just to compare the difference in size.

The problem is that default preferences get changed, and if I just save
instead of save as, I lose my work on the transparent parts of the
image.

Is there a way to hardcode preferences for saving a png?


Thanks
Pere
