RoboFab RSegment

Usage

f = OpenFont()

for c  in f:
	for contour in c:
		for segment in contour:
			print segment
>>> < RSegment for RoboFab Demo Font.R[0][0] >
	< RSegment for RoboFab Demo Font.R[0][1] >
	< RSegment for RoboFab Demo Font.R[0][2] >
	< RSegment for RoboFab Demo Font.R[0][3] >
	< RSegment for RoboFab Demo Font.R[0][4] >

    

Description

A Contour object is a list of segments. A segment is a list of points with some special attributes and methods. See the LettError wiki for a comprehensive explanation of segments.

Understanding Contours and outlines

The way outline data is organised in RoboFab, and how the various objects relate is described here: understanding contours.

Attributes

• type: Type of segment
• smooth: True if the segment is smooth, False if not.
• selected: Returns True if the segment is selected, False if not.
• points: List of points in the segment.
• onCurve: Returns the oncurve point associated with the segment.
• offCurve: Returns a list of offcurve points associated with the segment.

Attribute examples

f = OpenFont()

for c  in f:
	for contour in c:
		for segment in contour:
			print len(segment)
			print segment.type
			print segment.smooth
			print segment.points
			print segment.onCurve
			print segment.offCurve
			print segment.selected
    

Methods

• copy(): return a deepcopy of the object.
• move((x, y)): move the anchor of the bPoint to (x,y). The relative coordinates of the bcpIn and bcpOut will remain the same, which means that in fact, they move the same distance.
• round(): round the coordinates to whole integers.
• transform(matrix): Transform this point. Use a Transform matrix object to mess with the point. See how to use transformations.

Method examples

f = OpenFont()

for c  in f:
	for contour in c:
		for segment in contour:
			segment.move((50, 25))
