Hi Michael
Thank you very much for the reply. So the guide is wrong in the information. It says it´s an array of numbers, and the correct should be an array of arrays.
Your parameter worked. At true I´d like the inverse. I´d like to select the bottom portion (in my image, the white portion). But, sure I could inverse the selection and get it.
Anyway, I´m trying to understand the meaning of your arrays.
For example:
When you set [totalW, sizeH] or [0, sizeH], what means the first position of these arrays? How about the second?
Thank you very much
Gustavo.
