Does the Tkinter Canvas class have built-in true cubic Bezier curve drawing capability?
I am relatively new to Python and have just recently started looking at some of the methods associated with the Tkinter Canvas class. I see that Canvas has a create_line method, which can take a tuple of xi, yi coordinates of points, and there is a smooth=True flag that can be set, as well as a splinesteps value that can be set, which appears to control the number of curve components. Or, is there some other Tkinter function somewhere that would be more appropriate to use for drawing cubic Bezier curves. Is the above use of the create_line method with smooth=True essentially the same as the following code snippet, which illustrates how one could draw a cubic Bezier curve on the Mac using Objective-C and the Cocoa framework? In particular, the Objective-C code snippets below would be part of what is needed to draw a cubic Bezier curve whose control points are p[0], p[1], p[2], p[3] NSBezierPath * cubicPath_ = [[NSBezierPath alloc] init]; [cubicPath_ moveToPoint:p[0]]; [cubicPath_ curveToPoint:p[3] controlPoint1:p[1] controlPoint2:p[2]]; // Draw the cubic path in red [[NSColor redColor] set]; [cubicPath_ stroke]; [cubicPath_ release];
