Description: A collection of edges (Not necessarily describing closed contours)
Class hierarchy: Edges » ShapeCollection
Sub-classes: EdgeType
This class was introduced to simplify operations on edges sets. See Edge for a description of the individual edge object. The edge collection contains an arbitrary number of edges and supports operations to select edges by various criteria, produce polygons from the edges by applying an extension, filtering edges against other edges collections and checking geometrical relations to other edges (DRC functionality).
The edge collection is supposed to work closely with the Region polygon set. Both are related, although the edge collection has a lower rank since it potentially represents a disconnected collection of edges. Edge collections may form closed contours, for example immediately after they have been derived from a polygon set using Region#edges. But this state is volatile and can easily be destroyed by filtering edges. Hence the connected state does not play an important role in the edge collection's API.
Edge collections may also contain points (degenerated edges with identical start and end points). Such point-like objects participate in some although not all methods of the edge collection class. Edge collections can be used in two different flavors: in raw mode or merged semantics. With merged semantics (the default), connected edges are considered to belong together and are effectively merged. Overlapping parts are counted once in that mode. Dot-like edges are not considered in merged semantics. In raw mode (without merged semantics), each edge is considered as it is. Overlaps between edges may exists and merging has to be done explicitly using the merge method. The semantics can be selected using merged_semantics=.
This class has been introduced in version 0.23.

As a side effect, the edges are made non-intersecting by introducing cut points where edges intersect. Note that in Ruby, the '-=' operator actually does not exist, but is emulated by '-' followed by an assignment. This is less efficient than the in-place operation, so it is recommended to use 'not_with' instead.

_manage | Signature: void _manage Description: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. | ||||||||||||||||
_unmanage | Signature: void _unmanage Description: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. | ||||||||||||||||

If "whole_edges" is true, the resulting EdgePairs collection will receive the whole edges which contribute in the width check. "metrics" can be one of the constants Euclidian, Square or Projection. See there for a description of these constants. Use nil for this value to select the default (Euclidian metrics). "ignore_angle" specifies the angle threshold of two edges. If two edges form an angle equal or above the given value, they will not contribute in the check. Setting this value to 90 (the default) will exclude edges with an angle of 90 degree or more from the check. Use nil for this value to select the default. "min_projection" and "max_projection" allow selecting edges by their projected value upon each other. It is sufficient if the projection of one edge on the other matches the specified condition. The projected length must be larger or equal to "min_projection" and less than "max_projection". If you don't want to specify one threshold, pass nil to the respective value.

start_segments | Signature: [const] Edges start_segments (unsigned int length, double fraction) Description: Returns edges representing a part of the edge after the start point
This method allows one to specify the length of these segments in a twofold way: either as a fixed length or by specifying a fraction of the original length: edges = ... # An edge collection edges.start_segments(100, 0.0) # All segments have a length of 100 DBU edges.start_segments(0, 50.0) # All segments have a length of half the original length edges.start_segments(100, 50.0) # All segments have a length of half the original length # or 100 DBU, whichever is larger It is possible to specify 0 for both values.

If "whole_edges" is true, the resulting EdgePairs collection will receive the whole edges which contribute in the width check. "metrics" can be one of the constants Euclidian, Square or Projection. See there for a description of these constants. Use nil for this value to select the default (Euclidian metrics). "ignore_angle" specifies the angle threshold of two edges. If two edges form an angle equal or above the given value, they will not contribute in the check. Setting this value to 90 (the default) will exclude edges with an angle of 90 degree or more from the check. Use nil for this value to select the default.

with_angle | (1) Signature: [const] Edges with_angle (double angle, bool inverse) Description: Filters the edges by orientation Filters the edges in the edge collection by orientation. If "inverse" is false, only edges which have the given angle to the x-axis are returned. If "inverse" is true, edges not having the given angle are returned. This will select horizontal edges: horizontal = edges.with_angle(0, false) | ||||||||||||||||
(2) Signature: [const] Edges with_angle (double min_angle, double max_angle, bool inverse, bool include_min_angle = true, bool include_max_angle = false) Description: Filters the edges by orientation Filters the edges in the edge collection by orientation. If "inverse" is false, only edges which have an angle to the x-axis larger or equal to "min_angle" (depending on "include_min_angle") and equal or less than "max_angle" (depending on "include_max_angle") are returned. If "inverse" is true, edges which do not conform to this criterion are returned. With "include_min_angle" set to true (the default), the minimum angle is included in the criterion while with false, the minimum angle itself is not included.

xor_with | Signature: Edges xor_with (const Edges other) Description: Performs the boolean XOR between self and the other edge collection in-place (modifying self)
The boolean XOR operation will return all parts of the edges in this and the other collection except the parts where both are coincident. The result will be a merged edge collection. Note that in Ruby, the '^=' operator actually does not exist, but is emulated by '^' followed by an assignment. This is less efficient than the in-place operation, so it is recommended to use 'xor_with' instead. The 'xor_with' alias has been introduced in version 0.28.12. | ||||||||||||||||
| | Signature: [const] Edges | (const Edges other) Description: Returns the boolean OR between self and the other edge set
