path class

The path class is derived from a shape. A path is represented by a list of vertices, plus a width, style, beginExtent and endExtent. This class is normally created in a cellView using the dbCreatePath() function.

path::width(int32_t w)

Sets the path width to w.

int32_t path::width()

Gets the path width.

path::style(int32_t s)

Sets the path style, i.e. the type of the path end. The style can be one of: 0 - truncate, 1 - round, 2 - extend, 4 - varextend, 8 - octagonal. Python global variables TRUNCATE, ROUND, EXTEND, VAREXTEND, OCTAGONAL are defined to these values.

int32_t path::style()

Gets the path style.

path::beginExt(int32_t e)

Set the path begin extent. For a path style 2 (extend) or 4 (varextend) , this is the begin extent of the path.

int32_t path::beginExt()

Get the path begin extent. For a path style of 2 (extend) this is half the path's width. For a path style 4 (varextend), this is the begin extent of the path.

path::endExt(int32_t e)

Set the path end extent. For a path style 2 (extend) or 4 (varextend), this is the end extent of the path.

int32_t path::endExt()

Get the path end extent. For a path style of 2 (extend) this is half the path's width. For a path style 4 (varextend), this is the end extent of the path.

Rect path::bBox()

Get the bounding box of this path.

path::bBox(Rect b)

Set the bounding box of this path. Not useful and will throw an exception if called.

dbtype_t path::objType()

Returns the object type of this path as PATH.

char * path::objName()

Returns the object name of this path as "PATH".

int32_t n = path::nPoints()

Returns the number of points of the path.

Point * path::ptlist()

Returns the point list of this path as a C array of Points.

Point p[index]

Returns the Point p at the index into the list of points.

path::bias(int32_t bias, double grid)

Bias this path by bias, snapping to the grid grid.

path::scale(double scale, double grid)

Scale this path by scale, snapping to the grid grid.

int32_t path::getNearestEdge(Point p, segment &s)

Get the distance of the nearest segment s of this path to the point p;

int32_t d = path::getNearestVertex(Point p, vertex &s)

Get the distance of the nearest vertex s of this path to the point p;

double a = path::area()

Get the area of this path.

int32_t p = path::perimeter()

Get the perimeter of this path.

path::transform(transform trans)

Transform this path using trans.

bool path::ptInPoly(Point p)

Returns true if the Point p is contained in the path or on its edges.

path::Move(cellView *cv, Point delta, bool opt = true)

Move this path by distance delta. If opt is true then the database is re-optimised for the new path position. If there are a lot of objects to move it makes sense to turn this off and instead use the cellView update() function after moving them all.

dbObj * path::Copy(cellView *cv, Point delta, int32_t layerNum = -1)

Copy this path to cellView cv, with offset delta. If layerNum is a positive integer the path will be copied to the new layer number.

dbObj * path::Flatten(cellView *cv, transform trans)

Flatten this path into cellView cv with transformation trans.

path::Stretch(Point delta, segment seg)

Stretch segment seg of this path by delta.

path::compressPoints()

Removes colinear points from the path.

polygon * path::shapeToPoly ()

Converts this path to a polygon.
