CGraphicsComplexPolygon

class ikomia.core.pycore.CGraphicsComplexPolygon

Graphics item to display complex polygon (with holes) in the overlay layer of an image. Such graphics item is defined by an outer polygon and a list of inner polygons (holes). Each polygon is a list of vertices defined by 2D point (x,y). Derived from CGraphicsItem.

Import

from ikomia.core import CGraphicsComplexPolygon

Details

__init__((object)arg1) → None

__init__( (object)self) -> None :

Default constructor

__init__( (object)self, (object)outer, (object)inners) -> None :

Construct a complex polygon item.

Args:

outer (list of CPointF): vertices of outer polygon

inners (list of list of CPointF): each list corresponds to the vertices of one inner polygon (hole)

__init__( (object)self, (object)outer, (object)inners, (GraphicsPolygonProperty)property) -> None :

Construct a complex polygon item.

Args:

outer (list of CPointF): vertices of outer polygon

inners (list of list of CPointF): each list corresponds to the vertices of one inner polygon (hole)

property (GraphicsPolygonProperty): information and visual properties.

get_bounding_rect((CGraphicsItem)self) → object :

Get graphics item bounding rectangle.

Returns:

list of float: rectangle coordinate (left, top, width, height)

get_bounding_rect( (CGraphicsItem)arg1) -> None

get_category((CGraphicsItem)self) → str :

Get graphics item category.

Returns:

str: category (label)

get_category( (CGraphicsItem)arg1) -> None

get_id((CGraphicsItem)self) → int :

Get graphics item unique identifier.

Returns:

identifier

Return type:

int

get_type((CGraphicsItem)self) → GraphicsItem :

Get graphics item type. See GraphicsItem for possible values.

Returns:

type

Return type:

GraphicsItem

is_text_item((CGraphicsItem)self) → bool :

Check whether item type is TEXT. In case of object detection workflow, text graphics items should not be useful as input for another task. This method enables to filter only shape-based items (rectangle, polygon…) when processing graphics input.

Returns:

bool: True or False

is_text_item( (CGraphicsItem)self) -> bool

set_category((CGraphicsItem)self, (str)category) → None :

Set the graphics item category. It’s just a generic way to identify the item.

Args:

category (str): identification label

set_category( (CGraphicsItem)arg1, (str)arg2) -> None
