The ArcTo function draws an elliptical arc.
BOOL ArcTo(
HDC hdc, |
// handle to device context |
int nLeftRect, |
// x-coordinate of bounding rectangle’s upper-left corner |
int nTopRect, |
// y-coordinate of bounding rectangle’s upper-left corner |
int nRightRect, |
// x-coordinate of bounding rectangle’s lower-right corner |
int nBottomRect, |
// y-coordinate of bounding rectangle’s lower-right corner |
int nXRadial1, |
// x-coordinate of the first radial ending point |
int nYRadial1, |
// y-coordinate of the first radial ending point |
int nXRadial2, |
// x-coordinate of the second radial ending point |
int nYRadial2 |
// y-coordinate of the second radial ending point |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
ArcTo is similar to the Arc function, except that the current position is updated.
The points (nLeftRect, nTopRect) and (nRightRect, nBottomRect) specify the bounding rectangle. An ellipse formed by the specified bounding rectangle defines the curve of the arc. The arc extends counterclockwise from the point where it intersects the radial line from the center of the bounding rectangle to the (nXRadial1, nYRadial1) point. The arc ends where it intersects the radial line from the center of the bounding rectangle to the (nXRadial2, nYRadial2) point. If the starting point and ending point are the same, a complete ellipse is drawn.
A line is drawn from the current position to the starting point of the arc. If no error occurs, the current position is set to the ending point of the arc.
The arc is drawn using the current pen; it is not filled.
