ResourceImporterBitMap
======================

**Inherits:** :ref:`ResourceImporter<class_ResourceImporter>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Imports a :ref:`BitMap<class_BitMap>` resource (2D array of boolean values).

.. rst-class:: classref-introduction-group

Description
-----------

:ref:`BitMap<class_BitMap>` resources are typically used as click masks in :ref:`TextureButton<class_TextureButton>` and :ref:`TouchScreenButton<class_TouchScreenButton>`.

Property Descriptions
---------------------

.. _class_ResourceImporterBitMap_property_create_from:

.. rst-class:: classref-property

:ref:`int<class_int>` **create_from** = ``0``

The data source to use for generating the bitmap.

\ **Black & White:** Pixels whose HSV value is greater than the :ref:`threshold<class_ResourceImporterBitMap_property_threshold>` will be considered as "enabled" (bit is ``true``). If the pixel is lower than or equal to the threshold, it will be considered as "disabled" (bit is ``false``).

\ **Alpha:** Pixels whose alpha value is greater than the :ref:`threshold<class_ResourceImporterBitMap_property_threshold>` will be considered as "enabled" (bit is ``true``). If the pixel is lower than or equal to the threshold, it will be considered as "disabled" (bit is ``false``).

.. rst-class:: classref-item-separator

.. _class_ResourceImporterBitMap_property_threshold:

.. rst-class:: classref-property

:ref:`float<class_float>` **threshold** = ``0.5``

The threshold to use to determine which bits should be considered enabled or disabled. See also :ref:`create_from<class_ResourceImporterBitMap_property_create_from>`.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
