constructor

• new TextureDownloader(texture: Gdk.Texture): TextureDownloader

  Parameters

  • texture: Gdk.Texture

  Returns TextureDownloader

Static$gtype

Since 4.10copy

• copy(): TextureDownloader

  Creates a copy of the downloader.

  This function is meant for language bindings.

  Returns TextureDownloader

  A copy of the downloader

  Since

  4.10

Since 4.10download_bytes

• download_bytes(): [GLib.Bytes, number]

  Downloads the given texture pixels into a GLib.Bytes. 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 Gdk.TextureDownloader.download_into once allocation succeeded.

  This function cannot be used with a multiplanar format. Use Gdk.TextureDownloader.download_bytes_with_planes for that purpose.

  Returns [GLib.Bytes, number]

  The downloaded pixels

  Since

  4.10

Since 4.20download_bytes_with_planes

• download_bytes_with_planes(): [GLib.Bytes, number[], number[]]

  Downloads the given texture pixels into a GLib.Bytes. The offsets and strides of the resulting buffer will be stored in the respective values.

  If the format does have less than 4 planes, the remaining offsets and strides will be set to 0.

  Returns [GLib.Bytes, number[], number[]]

  The downloaded pixels

  Since

  4.20

Since 4.10download_into

• download_into(
      data: string | Uint8Array<ArrayBufferLike>,
      stride: number | bigint,
  ): void

  Downloads the texture into local memory.

  This function cannot be used with a multiplanar format.

  Parameters

  • data: string | Uint8Array<ArrayBufferLike>

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

  • stride: number | bigint

    rowstride in bytes

  Returns void

  Since

Since 4.10free

• free(): void

  Frees the given downloader and all its associated resources.

  Returns void

  Gets the color state that the data will be downloaded in.

  Returns Gdk.ColorState

  The color state of the download

  Since

Since 4.16set_color_state

• set_color_state(color_state: Gdk.ColorState): void

  Sets the color state the downloader will convert the data to.

  By default, the sRGB colorstate returned by ColorState.get_srgb is used.

  Parameters

  • color_state: Gdk.ColorState

    the color state to use

  Returns void

  Since

  4.16

Since 4.10set_format

• set_format(format: Gdk.MemoryFormat): void
