Description
Strikes through the manipulated text.
DrawSingleLine is implemented by descendants of TTextService in order to draw a line over the manipulated text.
The Canvas parameter specifies the rectangle area.
The ARect parameter specifies the rectangle area that frames the text.
The FirstVisibleChar parameter specifies an integer representing the start position for the drawing.
The Font parameter specifies the Font for the text.
The AOpacity parameter specifies the opacity for the text.
The Flags parameter specifies the reading direction of AText.
ATextAlign is the horizontal alignment of the text within ARect.
AVTextAlign is the vertical alignment of the text within ARect. AVTextAlign is optional. By default, it is set to Center.
