hu ? i thought It was starting counting from 0 ?
the 0 index seems to work
EDIT: but yes it works ! thanks a lot, but i would like to understand what gone wrong with this.
edit bis : Hoooo ok, i see :
the width and height of the array is a count not a max index, it integrates the 0.
So yes thats why. Silly i am.
Thank you so much ! cheers
