ellipse class

An ellipse is represented by a centre point and an X and Y radius. An ellipse is derived from a shape. If X and Y are equal, you have a circle. An ellipse is normally created by the cellView::dbCreateEllipse() or cellView::dbCreateCircle() function.

int32_t ellipse::left()

Returns the least X value of the ellipse’s bounding box.

int32_t ellipse::right()

Returns the greatest X value of the ellipse’s bounding box.

int32_t ellipse::bottom()

Returns the lowest Y value of the ellipse’s bounding box.

int32_t ellipse::top()

Returns the highest Y value of the ellipse’s bounding box.

ellipse::setOrigin(const Point &origin)

ellipse::setOrigin(int32_t x, int32_t y)

Sets the ellipse’s centre point.

Point ellipse::origin()

Returns the ellipse’s centre point.

int32_t ellipse::height()

Returns the height of the ellipse.

int32_t ellipse::width()

Returns the width of the ellipse.

Rect ellipse::bBox()

Returns the ellipse’s bounding box.

ellipse::setXRadius(int32_t r)

Set the X radius of the ellipse

ellipse::setYRadius(int32_t r)

Set the Y radius of the ellipse.

int32_t ellipse::xRadius()

Returns the X radius of the ellipse.

int32_t ellipse::yRadius()

Returns the Y radius of the ellipse.

ellipse::setNumChords(int32_t n)

Sets the number of edges that the ellipse will be fractured into when converting to a polygon.

int32_t ellipse::numChords()

Get the number of edges for the ellipse.

dbtype_t ellipse::objType()

Returns the object’s type as ELLIPSE

const char * ellipse::objName()

Returns the object’s name as “ELLIPSE”

float64_t ellipse::area()

Returns the ellipse’s area.

int32_t ellipse::perimeter()

Returns the ellipse’s perimeter.

bool ellipse::offGrid(int32_t grid)

Returns true if the ellipse’s xRadius or yRadius is offgrid.

ellipse::transform(transform trans)

Transforms the ellipse by trans.

ellipse::Move(cellView *dest, Point delta, bool opt=true)

Move this ellipse by distance delta. If opt is True then the database is re-optimised for the new rectangle 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 * ellipse::Copy(cellView *dest, Point delta, layer=-1)

Copy this ellipse to cellView dest, with offset delta. If layer is non negative the rectangle will be copied to the new layer number.

dbObjList<dbObj> * ellipse::Flatten(cellView *dest, transform trans, bool hier=true)

Flatten this ellipse into cellView dest with transformation trans.

ellipse::bias(int32_t bias, int32_t xgrid, int32_t ygrid, int16_t layer=-1)

Bias this ellipse by bias, snapping to the grid xgrid and ygrid.

ellipse::scale(float64_t scale, int32_t grid)

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