Properties:

• public Material cogl_material { get; set; }
• public Texture cogl_texture { get; set; }
• public bool disable_slicing { get; construct; }
• public string filename { owned get; set; }
  The path of the file containing the image data to be displayed by the texture.
• public TextureQuality filter_quality { get; set construct; }
• public bool keep_aspect_ratio { get; set; }
• public bool load_async { set; }
  Tries to load a texture from a filename by using a local thread to perform the read operations.
• public bool load_data_async { set; }
  Like load_async but loads the width and height synchronously causing some blocking.
• public bool pick_with_alpha { get; set; }
• public PixelFormat pixel_format { get; }
• public bool repeat_x { get; set; }
• public bool repeat_y { get; set; }
• public bool sync_size { get; set; }
• public int tile_waste { get; }

Creation methods:

• public Texture ()
  Creates a new empty Texture object.
• public Texture.from_actor (Actor actor)
  Creates a new Texture object with its source a prexisting actor (and associated children).
• public Texture.from_file (string filename) throws TextureError
  Creates a new ClutterTexture actor to display the image contained a file.

Methods:

• public void get_base_size (out int width, out int height)
  Gets the size in pixels of the untransformed underlying image
• public unowned Handle get_cogl_material ()
  Returns a handle to the underlying COGL material used for drawing the actor.
• public unowned Handle get_cogl_texture ()
  Retrieves the handle to the underlying COGL texture used for drawing the actor.
• public TextureQuality get_filter_quality ()
  Gets the filter quality used when scaling a texture.
• public bool get_keep_aspect_ratio ()
  Retrieves the value set using set_keep_aspect_ratio
• public bool get_load_async ()
  Retrieves the value set using set_load_async
• public bool get_load_data_async ()
  Retrieves the value set by set_load_data_async
• public int get_max_tile_waste ()
  Gets the maximum waste that will be used when creating a texture or -1 if slicing is disabled.
• public bool get_pick_with_alpha ()
  Retrieves the value set by set_load_data_async
• public PixelFormat get_pixel_format ()
  Retrieves the pixel format used by this .
• public void get_repeat (out bool repeat_x, out bool repeat_y)
  Retrieves the horizontal and vertical repeat values set using set_repeat
• public bool get_sync_size ()
  Retrieves the value set with set_sync_size
• public bool set_area_from_rgb_data (uint8[] data, bool has_alpha, int x, int y, int width, int height, int rowstride, int bpp, TextureFlags flags) throws Error
  Updates a sub-region of the pixel data in a Texture.
• public void set_cogl_material (Handle cogl_material)
  Replaces the underlying Cogl material drawn by this actor with cogl_material.
• public void set_cogl_texture (Handle cogl_tex)
  Replaces the underlying COGL texture drawn by this actor with cogl_tex.
• public void set_filter_quality (TextureQuality filter_quality)
  Sets the filter quality when scaling a texture.
• public bool set_from_file (string filename) throws Error
  Sets the Texture image data from an image file.
• public bool set_from_rgb_data (uint8[] data, bool has_alpha, int width, int height, int rowstride, int bpp, TextureFlags flags) throws Error
  Sets Texture image data.
• public bool set_from_yuv_data (uint8[] data, int width, int height, TextureFlags flags) throws Error
  Sets a Texture from YUV image data.
• public void set_keep_aspect_ratio (bool keep_aspect)
  Sets whether this should have a preferred size maintaining the aspect ratio of the underlying image
• public void set_load_async (bool load_async)
  Sets whether this should use a worker thread to load the data from disk asynchronously.
• public void set_load_data_async (bool load_async)
  Sets whether this should use a worker thread to load the data from disk asynchronously.
• public void set_pick_with_alpha (bool pick_with_alpha)
  Sets whether this should have it's shape defined by the alpha channel when picking.
• public void set_repeat (bool repeat_x, bool repeat_y)
  Sets whether the this should repeat horizontally or vertically when the actor size is bigger than the image size
• public void set_sync_size (bool sync_size)
  Sets whether this should have the same preferred size as the underlying image data.

Signals:

• public virtual signal void load_finished (Error error)
  The load_finished signal is emitted when a texture load has completed.
• public virtual signal void pixbuf_change ()
  The pixbuf_change signal is emitted each time the pixbuf used by texture changes.
• public virtual signal void size_change (int width, int height)
  The size_change signal is emitted each time the size of the pixbuf used by texture changes.
