Descripción
|
||
----------------------
|
||
|
||
A :ref:`Texture2D<class_Texture2D>` based on an :ref:`Image<class_Image>`. For an image to be displayed, an **ImageTexture** has to be created from it using the :ref:`create_from_image()<class_ImageTexture_method_create_from_image>` method:
|
||
|
||
::
|
||
|
||
var image = Image.load_from_file("res://icon.svg")
|
||
var texture = ImageTexture.create_from_image(image)
|
||
$Sprite2D.texture = texture
|
||
|
||
This way, textures can be created at run-time by loading images both from within the editor and externally.
|
||
|
||
\ **Warning:** Prefer to load imported textures with :ref:`@GDScript.load()<class_@GDScript_method_load>` over loading them from within the filesystem dynamically with :ref:`Image.load()<class_Image_method_load>`, as it may not work in exported projects:
|
||
|
||
::
|
||
|
||
var texture = load("res://icon.svg")
|
||
$Sprite2D.texture = texture
|
||
|
||
This is because images have to be imported as a :ref:`CompressedTexture2D<class_CompressedTexture2D>` first to be loaded with :ref:`@GDScript.load()<class_@GDScript_method_load>`. If you'd still like to load an image file just like any other :ref:`Resource<class_Resource>`, import it as an :ref:`Image<class_Image>` resource instead, and then load it normally using the :ref:`@GDScript.load()<class_@GDScript_method_load>` method.
|
||
|
||
\ **Note:** The image can be retrieved from an imported texture using the :ref:`Texture2D.get_image()<class_Texture2D_method_get_image>` method, which returns a copy of the image:
|
||
|
||
::
|
||
|
||
var texture = load("res://icon.svg")
|
||
var image = texture.get_image()
|
||
|
||
An **ImageTexture** is not meant to be operated from within the editor interface directly, and is mostly useful for rendering images on screen dynamically via code. If you need to generate images procedurally from within the editor, consider saving and importing images as custom texture resources implementing a new :ref:`EditorImportPlugin<class_EditorImportPlugin>`.
|
||
|
||
\ **Note:** The maximum texture size is 16384×16384 pixels due to graphics hardware limitations.

Crea una nueva **ImageTexture** y la inicializa asignando y estableciendo los datos de una :ref:`Image<class_Image>`.

Reemplaza los datos de la textura con una nueva :ref:`Image<class_Image>`. Esto volverá a asignar nueva memoria para la textura.
|
||
|
||
Si quieres actualizar la imagen, pero no necesitas cambiar sus parámetros (formato, tamaño), usa :ref:`update()<class_ImageTexture_method_update>` en su lugar para un mejor rendimiento.

|void| **update**\ (\ image\: :ref:`Image<class_Image>`\ ) :ref:`🔗<class_ImageTexture_method_update>`
|
||
|
||
Reemplaza los datos de la textura con una nueva :ref:`Image<class_Image>`.
|
||
|
||
\ **Nota:** La textura tiene que ser creada usando :ref:`create_from_image()<class_ImageTexture_method_create_from_image>` o inicializada primero con el método :ref:`set_image()<class_ImageTexture_method_set_image>` antes de que pueda ser actualizada. Las nuevas dimensiones de la imagen, el formato y la configuración de mipmaps deben coincidir con la configuración de la imagen de la textura existente.
|
||
|
||
Usa este método en lugar de :ref:`set_image()<class_ImageTexture_method_set_image>` si necesitas actualizar la textura con frecuencia, lo cual es más rápido que asignar memoria adicional para una nueva textura cada vez.
