With the DATA (X Y)
Turn the RE counter-clockwise a few times
will return it to the initial value.
In the case of using a mouse, rotating the mouse

Coordinate reference point
This 4096 x 2160, Full-HD panel has a pixel
reference point (0001, 0001) at the top left of the
screen. The pixel at the bottom right of the
screen is preset as the coordinates (4096, 2160).
X axis
Y axis
Marker lines and coordinate values
There are 4 line widths for the user markers.
However, the coordinate for the start point and
that for the end point are different by 3 pixel.
Pixel position in the coordinate for the "start point"
Line width: 2 pixels

Accordingly, in drawing a horizontal line, the
Y-direction address has a coordinate value with
3pixel added, as shown below.
Pixel position (X, Y) in the coordinate for the "start point"
Pixel position (X+a, Y+3) in the coordinate for the "end point"
When a vertical line is drawn, the X-axis address
has a coordinate value with 3 pixel added, as
shown below.
Pixel position (X, Y) in the coordinate for the "start point".
Pixel position (X+a, Y+3) in the coordinate for the "end point".
