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.
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.
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.

CLUTTER_TEXTURE_ERROR
#define CLUTTER_TEXTURE_ERROR (clutter_texture_error_quark ())
Error domain for ClutterTexture errors
Since: 0.4
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.

clutter_texture_set_from_yuv_data ()
gboolean clutter_texture_set_from_yuv_data (ClutterTexture *texture,const guchar *data,gint width,gint height,ClutterTextureFlags flags,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.

void clutter_texture_set_filter_quality (ClutterTexture *texture,ClutterTextureQuality filter_quality);
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()

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.

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

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.

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.

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.
