## Implemented Interfaces

ClutterTexture implements ClutterContainer, ClutterScriptable, ClutterAnimatable and AtkImplementorIface.

## Description

ClutterTexture is a base class for displaying and manipulating pixel buffer type data.

The `clutter_texture_set_from_rgb_data()` and `clutter_texture_set_from_file()` functions are used to copy image data into texture memory and subsequently realize the texture.

Note: a ClutterTexture will scale its contents to fit the bounding box requested using `clutter_actor_set_size()`. To display an area of a texture without scaling, you should set the clip area using `clutter_actor_set_clip()`.

The ClutterTexture API is deprecated since Clutter 1.12. It is strongly recommended to use ClutterImage instead.

## Functions

### clutter_texture_new ()

    ClutterActor *
    clutter_texture_new (void);

`clutter_texture_new` has been deprecated since version 1.12 and should not be used in newly-written code.

Use ClutterImage instead

Creates a new empty ClutterTexture object.

#### Returns

A newly created ClutterTexture object.

### clutter_texture_new_from_file ()

    ClutterActor *
    clutter_texture_new_from_file (const gchar *filename,
                                   GError **error);

`clutter_texture_new_from_file` has been deprecated since version 1.12 and should not be used in newly-written code.

No direct replacement is available. Use ClutterImage and platform-specific image loading API, like GdkPixbuf, instead

Creates a new ClutterTexture actor to display the image contained a file. If the image failed to load then NULL is returned and `error` is set.

#### Parameters

filename | The name of an image file to load. |
error | Return locatoin for an error. |

#### Returns

A newly created ClutterTexture object or NULL on error.

Since: 0.8

### clutter_texture_new_from_actor ()

    ClutterActor *
    clutter_texture_new_from_actor (ClutterActor *actor);

`clutter_texture_new_from_actor` has been deprecated since version 1.8 and should not be used in newly-written code.

Use the ClutterOffscreenEffect and ClutterShaderEffect directly on the intended ClutterActor to replace the functionality of this function.

Creates a new ClutterTexture object with its source a prexisting actor (and associated children). The textures content will contain 'live' redirected output of the actors scene.

Note this function is intented as a utility call for uniformly applying shaders to groups and other potential visual effects. It requires that the `CLUTTER_FEATURE_OFFSCREEN` feature is supported by the current backend and the target system.

Some tips on usage:

- The source actor must be visible

- The source actor must have a parent in order for it to be allocated a size from the layouting mechanism. If the source actor does not have a parent when this function is called then the ClutterTexture will adopt it and allocate it at its preferred size. Using this you can clone an actor that is otherwise not displayed. Because of this feature if you do intend to display the source actor then you must make sure that the actor is parented before calling `clutter_texture_new_from_actor()` or that you unparent it before adding it to a container.

- When getting the image for the clone texture, Clutter will attempt to render the source actor exactly as it would appear if it was rendered on screen. The source actor's parent transformations are taken into account. Therefore if your source actor is rotated along the X or Y axes so that it has some depth, the texture will appear differently depending on the on-screen location of the source actor. While painting the source actor, Clutter will set up a temporary asymmetric perspective matrix as the projection matrix so that the source actor will be projected as if a small section of the screen was being viewed. Before version 0.8.2, an orthogonal identity projection was used which meant that the source actor would be clipped if any part of it was not on the zero Z-plane.

- Avoid reparenting the source with the created texture.

- A group can be padded with a transparent rectangle as to provide a border to contents for shader output (blurring text for example).

- The texture will automatically resize to contain a further transformed source. However, this involves overhead and can be avoided by placing the source actor in a bounding group sized large enough to contain any child tranformations.

- Uploading pixel data to the texture (e.g by using `clutter_texture_set_from_file()`) will destroy the offscreen texture data and end redirection.

- cogl_texture_get_data() with the handle returned by `clutter_texture_get_cogl_texture()` can be used to read the offscreen texture pixels into a pixbuf.

#### Parameters

actor | A source ClutterActor |

#### Returns

A newly created ClutterTexture object, or `NULL` on failure.

Since: 0.6

### clutter_texture_set_from_file ()

    gboolean
    clutter_texture_set_from_file (ClutterTexture *texture,
                                   const gchar *filename,
                                   GError **error);

`clutter_texture_set_from_file` has been deprecated since version 1.12 and should not be used in newly-written code.

Use ClutterImage and platform-specific image loading API, like GdkPixbuf, instead

Sets the ClutterTexture image data from an image file. In case of failure, `FALSE` is returned and `error` is set.

If “load-async” is set to `TRUE`, this function will return as soon as possible, and the actual image loading from disk will be performed asynchronously. “size-change” will be emitten when the size of the texture is available and “load-finished” will be emitted when the image has been loaded or if an error occurred.

#### Parameters

texture | A ClutterTexture |
filename | The filename of the image in GLib file name encoding |
error | Return location for a GError, or `NULL` |

#### Returns

`TRUE` if the image was successfully loaded and set

Since: 0.8

                                       GError **error);

`clutter_texture_set_from_yuv_data` has been deprecated since version 1.10 and should not be used in newly-written code.

Use a custom ClutterContent implementation and set up the Cogl pipeline using a ClutterPipelineNode with a fragment shader instead.

Sets a ClutterTexture from YUV image data. If an error occurred, `FALSE` is returned and `error` is set.

The YUV support depends on the driver; the format supported by the few drivers exposing this capability are not really useful.

The proper way to convert image data in any YUV colorspace to any RGB colorspace is to use a fragment shader associated with the ClutterTexture material.

#### Parameters

texture | A ClutterTexture |
data | Image data in YUV type colorspace. | [array]
width | Width in pixels of image data. |
height | Height in pixels of image data |
flags | ClutterTextureFlags |
error | Return location for a GError, or `NULL`. |

#### Returns

`TRUE` if the texture was successfully updated

`clutter_texture_set_filter_quality` has been deprecated since version 1.12 and should not be used in newly-written code.

Use ClutterImage and `clutter_actor_set_content_scaling_filters()` instead

Sets the filter quality when scaling a texture. The quality is an enumeration currently the following values are supported: `CLUTTER_TEXTURE_QUALITY_LOW` which is fast but only uses nearest neighbour interpolation. `CLUTTER_TEXTURE_QUALITY_MEDIUM` which is computationally a bit more expensive (bilinear interpolation), and `CLUTTER_TEXTURE_QUALITY_HIGH` which uses extra texture memory resources to improve scaled down rendering as well (by using mipmaps). The default value is `CLUTTER_TEXTURE_QUALITY_MEDIUM`.

#### Parameters

texture | a ClutterTexture |
filter_quality | new filter quality value |

Since: 0.8

### clutter_texture_get_cogl_texture ()

    CoglHandle
    clutter_texture_get_cogl_texture (ClutterTexture *texture);

`clutter_texture_get_cogl_texture` has been deprecated since version 1.12 and should not be used in newly-written code.

No replacement available; it's not advisable to modify the Cogl pipeline of an actor. Use a ClutterContent implementation and set up the pipeline during the paint sequence instead.

Retrieves the handle to the underlying COGL texture used for drawing the actor. No extra reference is taken so if you need to keep the handle then you should call `cogl_handle_ref()` on it.

The texture handle returned is the first layer of the material handle used by the ClutterTexture. If you need to access the other layers you should use `clutter_texture_get_cogl_material()` instead and use the CoglMaterial API.

#### Parameters

texture | A ClutterTexture |

#### Returns

a CoglHandle for the texture. The returned handle is owned by the ClutterTexture and it should not be unreferenced.

[transfer none]

No replacement available; it's not advisable to modify the Cogl pipeline of an actor. Use a ClutterContent implementation and set up the pipeline during the paint sequence instead.

Replaces the underlying COGL texture drawn by this actor with `cogl_tex` . A reference to the texture is taken so if the handle is no longer needed it should be deref'd with cogl_handle_unref.

#### Parameters

texture | A ClutterTexture |
cogl_tex | A CoglHandle for a texture |

Since: 0.8

No replacement is available; it's not advisable to modify the Cogl pipeline of an actor. Use a ClutterContent implementation and modify the pipeline during the paint sequence

Replaces the underlying Cogl material drawn by this actor with `cogl_material` . A reference to the material is taken so if the handle is no longer needed it should be deref'd with cogl_handle_unref. Texture data is attached to the material so calling this function also replaces the Cogl texture. ClutterTexture requires that the material have a texture layer so you should set one on the material before calling this function.

#### Parameters

texture | A ClutterTexture |
cogl_material | A CoglHandle for a material |

`clutter_texture_get_load_data_async` has been deprecated since version 1.12 and should not be used in newly-written code.

There is no direct replacement for this function

Retrieves the value set by `clutter_texture_set_load_data_async()`

#### Parameters

texture | a ClutterTexture |

#### Returns

`TRUE` if the ClutterTexture should load the image data from a file asynchronously

Since: 1.0

### clutter_texture_set_load_data_async ()

    void
    clutter_texture_set_load_data_async (ClutterTexture *texture,
                                         gboolean load_async);

`clutter_texture_set_load_data_async` has been deprecated since version 1.12 and should not be used in newly-written code.

There is no direct replacement for this function. Use ClutterImage and platform-specific API for loading image data asynchronously, like GdkPixbuf

Sets whether `texture` should use a worker thread to load the data from disk asynchronously. Setting `load_async` to `TRUE` will make `clutter_texture_set_from_file()` block until the ClutterTexture has determined the width and height of the image data.

See the “load-async” property documentation, and `clutter_texture_set_load_async()`.

#### Parameters

texture | a ClutterTexture |
load_async | `TRUE` if the texture should asynchronously load data from a filename |

Since: 1.0

### clutter_texture_get_pick_with_alpha ()

    gboolean
    clutter_texture_get_pick_with_alpha (ClutterTexture *texture);

`clutter_texture_get_pick_with_alpha` has been deprecated since version 1.12 and should not be used in newly-written code.

There is no direct replacement for this function

Retrieves the value set by `clutter_texture_set_load_data_async()`

#### Parameters

texture | a ClutterTexture |

#### Returns

`TRUE` if the ClutterTexture should define its shape using the alpha channel when picking.

Since: 1.4

### clutter_texture_set_pick_with_alpha ()

    void
    clutter_texture_set_pick_with_alpha (ClutterTexture *texture,
                                         gboolean pick_with_alpha);

`clutter_texture_set_pick_with_alpha` has been deprecated since version 1.12 and should not be used in newly-written code.

There is no direct replacement for this function

Sets whether `texture` should have it's shape defined by the alpha channel when picking.

Be aware that this is a bit more costly than the default picking due to the texture lookup, extra test against the alpha value and the fact that it will also interrupt the batching of geometry done internally.

Also there is currently no control over the threshold used to determine what value of alpha is considered pickable, and so only fully opaque parts of the texture will react to picking.

#### Parameters

texture | a ClutterTexture |
pick_with_alpha | `TRUE` if the alpha channel should affect the picking shape |

Since: 1.4
