MaskedStrech unable to auto strech (to dark image)

Hello
This is new to me;  I've never had problems with this.

I attached screenshot  of PI, where you can see the console output, the error message and the image I'm processing.

Hi Geert, you have to set a Background reference of the image with the value of Upper limit. That should solve the error.
This process example may help.

Saludos, Alejandro.

Hello Alejandro.
The background reference is the image itself (target).
I never had to set a different background refentece before.

No bug here, just normal behavior. However, everything is guess work without the image in question.

Sorry Juan I Did'nt see your reply. By this time I already found a work arround (using the masked stretch script).
It may be usefull to include the minimum level where this procedure can be applied in a tooltip.
