Draw on the background canvas a filled square whose sides are of length 2r, centered on (x, y).

Draw a filled triangle on the canvas with corners at (x0, y0), (x1, y1), and (x2, y2).

Return the height of the current canvas

Return the width of the current canvas

Returns the value of _penColor as an object of class Color.

Return the color of the pixel at the given user coordinates

Return True if the queue of keys the user typed is not empty. Otherwise return False.

Draw on the background canvas a line from (x0, y0) to (x1, y1).

Return True if the mouse has been left-clicked since the last time mousePressed was called, and False otherwise.

Return the x coordinate in user space of the location at which the mouse was most recently left-clicked. If a left-click hasn't happened yet, raise an exception, since mouseX() shouldn't be called until mousePressed() returns True.

Return the y coordinate in user space of the location at which the mouse was most recently left-clicked. If a left-click hasn't happened yet, raise an exception, since mouseY() shouldn't be called until mousePressed() returns True.

Remove the first key from the queue of keys that the the user typed, and return that key.

Draw pic on the background canvas centered at (x, y). pic is an object of class picture.Picture. x and y default to the midpoint of the background canvas.

Draw on the background canvas a point at (x, y).

Draw on the background canvas a polygon with coordinates (x[i], y[i]).

Draw on the background canvas a polyline with coordinates (x[i], y[i]).

Draw a quadrilateral on the canvas with corners at (x0, y0), (x1, y1), (x2, y2), and (x3, y3).

Draw on the background canvas a rectangle of width (2 * halfWidth and height (2 * halfHeight) centered at point (x, y).

Save the window canvas to file f.

Draw a sector portion between angle1 and angle2, of the interior of a circle centered at (x, y) with a radius r.

Set the size of the canvas to w pixels wide and h pixels high. Calling this function is optional. If you call it, you must do so before calling any drawing function.

Set the font family to f (e.g. 'Helvetica' or 'Courier').

Set the font size to s (e.g. 12 or 16).

Set the pen color to c, where c is an object of class Color. c defaults to dudraw.BLACK.

Set the pen color to c, where c is an object of class Color. c defaults to dudraw.BLACK.

Set the pen radius to r, thus affecting the subsequent drawing of points and lines. If r is 0.0, then points will be drawn with the minimum possible radius and lines with the minimum possible width.

Undocumented

Set the x-scale of the canvas such that the minimum x value is min and the maximum x value is max.

Set the y-scale of the canvas such that the minimum y value is min and the maximum y value is max.

Copy the background canvas to the window canvas, and then wait for msec milliseconds. msec defaults to infinity.

Draw on the background canvas a square whose sides are of length 2r, centered on (x, y).

Draw string s on the background canvas centered at (x, y).

Draw a triangle on the canvas with corners at (x0, y0), (x1, y1), and (x2, y2).
