<h3>Usage</h3>
|

|
|
<pre>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] >

<h3>Description</h3>
|
||
|
|
<p>
|
||
|
|
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 <a href="http://just.letterror.com/ltrwiki/SegmentsVersusPoints">comprehensive explanation of segments</a>.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>Understanding Contours and outlines</h3>
|
||
|
|
<p>
|
||
|
|
The way outline data is organised in RoboFab, and how the various objects relate is described here: <a href="../howto/understandcontours.html">understanding contours</a>.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>Attributes</h3>
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
<strong>type</strong>: Type of segment
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<strong>smooth</strong>: True if the segment is smooth, False if not.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<strong>selected</strong>: Returns True if the segment is selected, False if not.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<strong>points</strong>: List of points in the segment.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<strong>onCurve</strong>: Returns the oncurve point associated with the segment.
|
||
|
|
</li>
|
||
|
|
<li>
|
||
|
|
<strong>offCurve</strong>: Returns a list of offcurve points associated with the segment.
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<h3>Attribute examples</h3>
|
||
|
|
<pre>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
|
||
|
|
</pre>
|
||
|
|
<h3>Methods</h3>
|
||
|
|
<p>
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li><strong>copy()</strong>: return a deepcopy of the object.</li>
|
||
|
|
<li><strong>move((x, y))</strong>: 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.</li>
|
||
|
|
<li><strong>round()</strong>: round the coordinates to whole integers.</li>
|
||
|
|
<li><strong>transform(matrix)</strong>: Transform this point. Use a Transform matrix
|
||
|
|
object to mess with the point. <a href="../howto/usetransformations.html">See how to use transformations</a>.</li>
|
||
|
|
</ul>
