ImageTexture

继承： Texture2D < Texture < Resource < RefCounted < Object

A Texture2D based on an Image.

描述

A Texture2D based on an Image. For an image to be displayed, an ImageTexture has to be created from it using the 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 @GDScript.load over loading them from within the filesystem dynamically with Image.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 CompressedTexture2D first to be loaded with @GDScript.load. If you'd still like to load an image file just like any other Resource, import it as an Image resource instead, and then load it normally using the @GDScript.load method.

Note: The image can be retrieved from an imported texture using the Texture2D.get_image method, which returns a copy of the image:

    var texture = load("res://icon.svg")
    var image: 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 EditorImportPlugin.

Note: The maximum texture size is 16384×16384 pixels due to graphics hardware limitations.

属性

方法

方法说明

ImageTexture create_from_image ( image: Image ) static¹

Creates a new ImageTexture and initializes it by allocating and setting the data from an Image.

Format get_format ( ) const²

Returns the format of the texture, one of Format.

void set_image ( image: Image )

Replaces the texture's data with a new Image. This will re-allocate new memory for the texture.

If you want to update the image, but don't need to change its parameters (format, size), use update instead for better performance.

void set_size_override ( size: Vector2i )

Resizes the texture to the specified dimensions.

void update ( image: Image )

Replaces the texture's data with a new Image.

Note: The texture has to be created using create_from_image or initialized first with the set_image method before it can be updated. The new image dimensions, format, and mipmaps configuration should match the existing texture's image configuration.

Use this method over set_image if you need to update the texture frequently, which is faster than allocating additional memory for a new texture each time.
