    "LineNumber": "1,3,5,7-10"
}

FirstPoint

The first point of the line, which is usually the top-left corner.

Remarks
View the texts in 0 degree, the first point is the top-left point of the area defined by LineSpecification, and the other three points are in a clockwise direction.
The ordinate origin is the top-left corner of the TextArea.
The value of x is a percentage value relative to the width of the TextArea.
The value of y is a percentage value relative to the height of the TextArea.
The allowed values for x/y: [0, 100].
It is valid only when ‘LineNumber’ is setting to one specified line number.
