When designing in the vertical direction

[Ebun.1]

Thank you for helping.

environment:

TouchGFX Ver4.15.0

When designing the screen design vertically

Will the points x0 and y0 be at the bottom right of the screen?

Or is it in the upper left?

Where is this specification written?

Supplement.

I designed a vertical screen and put a button on the upper left.

The coordinates of x and y were 0, 0.

But these coordinates are different from what you actually start writing the data.

The point at x = y = 0 should actually be in the lower left or upper right.

The red part in the figure.

Is the actual point of x = y = 0 at the bottom left? Or is it in the upper right?
