    Collapse AllThis method creates an elliptically curved path between points.
|
| HRESULT DrawArcTo ( FLOAT left, FLOAT top, FLOAT right, FLOAT bottom, FLOAT firstX, FLOAT firstY, FLOAT secondX, FLOAT secondY, VARIANT_BOOL isClockwise ) |
Parameters
left
X coordinate of the top-left corner of the bounding rectangle
top
Y coordinate of the top-left corner of the bounding rectangle
right
X coordinate of the bottom-right corner of the bounding rectangle
bottom
Y coordinate of the bottom-right corner of the bounding rectangle
firstX
X coordinate of the 1st point
firstY
Y coordinate of the 1st point
secondX
X coordinate of the 2nd point
secondY
Y coordinate of the 2nd point
isClockwise
Drawing direction: Clockwise, if true; counterclockwise, if false.
Return value
If successful, this method returns S_OK. If it fails, this method should return one of the error values.
Remarks
This method draws a path as a part of an ellipse that is bounded by the rectangle with top-left corner (left, top) and bottom-right corner (right, bottom). The arc is drawn following the perimeter of the ellipse, in the isClockwise direction, from the starting point to the ending point. The starting point is defined by the intersection of the ellipse and a line drawn from the center of the ellipse to the point (firstX, firstY). The ending point is defined by the intersection of the ellipse and a line drawn from the center of the ellipse to the point (secondX, secondY).
