TextureDownloader

Added in version 4.10.

class TextureDownloader(**kwargs)

The GdkTextureDownloader is used to download the contents of a Texture.

It is intended to be created as a short-term object for a single download, but can be used for multiple downloads of different textures or with different settings.

GdkTextureDownloader can be used to convert data between different formats. Create a GdkTexture for the existing format and then download it in a different format.

Constructors

class TextureDownloader

classmethod new(texture: Texture) → TextureDownloader

Creates a new texture downloader for texture.

By default, the downloader will convert the data to the default memory format, and to the sRGB color state.

Added in version 4.10.

Parameters:

texture – texture to download

Methods

class TextureDownloader

download_bytes() → tuple[Bytes, int]

Downloads the given texture pixels into a GBytes. The rowstride will be stored in the stride value.

This function will abort if it tries to download a large texture and fails to allocate memory. If you think that may happen, you should handle memory allocation yourself and use download_into once allocation succeeded.

Added in version 4.10.

download_into(data: list[int], stride: int) → None

Downloads the texture into local memory.

Added in version 4.10.

Parameters:

• data – pointer to enough memory to be filled with the downloaded data of the texture

• stride – rowstride in bytes

free() → None

Frees the given downloader and all its associated resources.
