Descripción
|
|
----------------------
|
|
|
|
Un array bidimensional de valores booleanos, puede ser usada para almacenar eficientemente un array binario (cada elemento del array toma sólo un bit) y consultar los valores usando coordenadas cartesianas naturales.

Devuelve una imagen del mismo tamaño que el mapa de bits y con un :ref:`Format<enum_Image_Format>` de tipo :ref:`Image.FORMAT_L8<class_Image_constant_FORMAT_L8>`. Los bits ``true`` del mapa de bits se convierten en píxeles blancos, y los bits ``false`` en negros.

|
|
|
|
Crea un mapa de bits que coincide con las dimensiones de la imagen dada, cada elemento del mapa de bits se establece en ``false`` si el valor alfa de la imagen en esa posición es igual o menor que ``threshold``, y ``true`` en caso contrario.

|
Aplica la dilatación o erosión morfológica al mapa de bits. Si ``pixels`` es positivo, se aplica la dilatación al mapa de bits. Si ``pixels`` es negativo, se aplica la erosión al mapa de bits. ``rect`` define el área donde se aplica la operación morfológica. Los píxeles situados fuera de ``rect`` no se ven afectados por :ref:`grow_mask()<class_BitMap_method_grow_mask>`.

|
|
|
|
Creates an :ref:`Array<class_Array>` of polygons covering a rectangular portion of the bitmap. It uses a marching squares algorithm, followed by Ramer-Douglas-Peucker (RDP) reduction of the number of vertices. Each polygon is described as a :ref:`PackedVector2Array<class_PackedVector2Array>` of its vertices.
|
|
|
|
To get polygons covering the whole bitmap, pass:
|
|
|
|
::
|
|
|
|
Rect2(Vector2(), get_size())
|
|
|
|
\ ``epsilon`` is passed to RDP to control how accurately the polygons cover the bitmap: a lower ``epsilon`` corresponds to more points in the polygons.
