Rio's parameters in rect. and circular mode

[afshinjian]

Hello
Thank you for your good library.
I need more explanation about determining Rio's parameters in square mode.
Most of the coordinate determination is what I want. Are the X and Y points defined based on the bottom left?
What are the maximum width and length values?
I would be grateful if you could give more details.
Also in circular mode.
Sincerely

Hi.
Thank you for the great work. I have the same doubt as afshinjian, if for example I use Eloquent::Esp32cam::Motion::RoI::Rect rect1(1, 2, 6, 4, 0.5); does it correspond to a rectangle that starts at the position with coordinates X=1, Y=2 with the top left of the image being the origin? as in the image in the link https://i.postimg.cc/L66mwQNH/coordinatesystem-rect-antialias.png
thank you very much.

The problem was solved with the example 13_Motion_Live_Feed_With_RoIs.ino
