What are the x and Y parameters in the PHP imagettftext () function?

On the internet, there is said that the upper left corner is located on the left, there is said to be the lower right corner of the coordinates, the manual said:

X
The coordinates represented by X, y define the basic point of the first character (presumably the lower-left corner of the character). This differs from imagestring (), where x, y defines the upper-left corner of the first character. For example, "top left" is 0, 0.

Y
The Y-coordinate. It sets the position of the font baseline, not the bottom of the character.

= =. I tested a few, always feel the wrong way, I have been muddy off. Ask you, what is this x/y exactly?
