|
| arc |
| :: Point | a corner of the rectangle bounding the ellipse. | | -> Point | the opposite corner of the rectangle bounding the ellipse. | | -> Angle | the start angle of the arc, measured counter-clockwise
from the horizontal. | | -> Angle | the extent of the arc, measured counter-clockwise from
the start angle. | | -> Graphic | a filled shape | | A filled arc from an ellipse. |
|
|
| ellipse |
| :: Point | a corner of the rectangle bounding the ellipse. | | -> Point | the opposite corner of the rectangle bounding the ellipse. | | -> Graphic | a filled shape | | A filled ellipse that fits inside a rectangle defined by two
Points on the window. |
|
|
| shearEllipse |
| :: Point | a corner of the bounding parallelogram. | | -> Point | another corner of the parallelogram, adjacent to the first. | | -> Point | another corner of the parallelogram, adjacent to the first
and thus opposite to the second. | | -> Graphic | a filled shape | | A filled sheared ellipse that fits inside a parallelogram defined
by three Points on the window. This function is implemented using
polygons on both Win32 and X11. |
|
|
| line :: Point -> Point -> Graphic |
| A line between two Points. |
|
| polyline :: [Point] -> Graphic |
| A series of lines through a list of Points. |
|
| polygon :: [Point] -> Graphic |
| A filled polygon defined by a list of Points. |
|
| polyBezier :: [Point] -> Graphic |
| A series of (unfilled) Bezier curves defined by a list of 3n+1
control Points. This function is not supported on X11 (it yields
an error message and a polyline). |
