Description

Functions

meta_shaped_texture_new ()

ClutterActor *
meta_shaped_texture_new (void);

meta_shaped_texture_set_create_mipmaps ()

void
meta_shaped_texture_set_create_mipmaps
                               (MetaShapedTexture *stex,
                                gboolean create_mipmaps);

meta_shaped_texture_update_area ()

gboolean
meta_shaped_texture_update_area (MetaShapedTexture *stex,
                                 int x,
                                 int y,
                                 int width,
                                 int height);

Repairs the damaged area indicated by x , y , width and height and potentially queues a redraw.

Parameters

stex

MetaShapedTexture

 

x

the x coordinate of the damaged area

 

y

the y coordinate of the damaged area

 

width

the width of the damaged area

 

height

the height of the damaged area

 

Returns

Whether a redraw have been queued or not


meta_shaped_texture_get_texture ()

CoglTexture *
meta_shaped_texture_get_texture (MetaShapedTexture *stex);

Parameters

stex

The MetaShapedTexture

 

Returns

the unshaped texture.

meta_shaped_texture_set_mask_texture ()

void
meta_shaped_texture_set_mask_texture (MetaShapedTexture *stex,
                                      CoglTexture *mask_texture);

meta_shaped_texture_get_image ()

cairo_surface_t *
meta_shaped_texture_get_image (MetaShapedTexture *stex,
                               cairo_rectangle_int_t *clip);

Flattens the two layers of the shaped texture into one ARGB32 image by alpha blending the two images, and returns the flattened image.

Parameters

stex

A MetaShapedTexture

 

clip

A clipping rectangle, to help prevent extra processing. In the case that the clipping rectangle is partially or fully outside the bounds of the texture, the rectangle will be clipped.

 

Returns

a new cairo surface to be freed with cairo_surface_destroy().
