DrawTextArcA
Text, Page layout
Description
The trailing A denotes the ANSI (char) DLL entry point; the ActiveX/COM surface exposes only the Unicode form. Behaviour is identical to DrawTextArc and string arguments are interpreted using the current SetAnsiMode code page
Draws text fitted to an imaginary arc with the specified center point and radius. The text will be drawn with it's left edge at the requested angle, where 0 degrees is the "12 o'clock" position, and positive angles are clockwise. The SetTextAlign function can be used to change the alignment of the text relative to the specified angle.
