Class
MetaMultiTexture
since: 13
Constructors
meta_multi_texture_new
Creates a MetaMultiTexture
with the given format
. Each of the
CoglTexture
s represents a plane.
since: 13
meta_multi_texture_new_simple
Creates a MetaMultiTexture
for a “simple” texture, i.e. with only one
plane, in a format that can be represented using CoglPixelFormat
.

Instance methods
meta_multi_texture_get_format
Returns the MetaMultiTextureFormat
that is used by this texture.
since: 13
meta_multi_texture_get_height
Returns the height of the MetaMultiTexture
. Prefer this over calling
cogl_texture_get_height()
on one of the textures, as that might give a
different size when dealing with subsampling.
since: 13
meta_multi_texture_get_n_planes
Returns the number of planes for this texture. Note that this is entirely
dependent on the CoglPixelFormat
that is used. For example, simple RGB
textures will have a single plane, while some more convoluted formats like
NV12 and YUV 4:4:4 can have 2 and 3 planes respectively.
since: 13
meta_multi_texture_get_plane
Returns the n’th plane of the MetaMultiTexture
. Note that it’s a programming
error to use with an index larger than meta_multi_texture_get_n_planes().
since: 13
meta_multi_texture_get_width
Returns the width of the MetaMultiTexture
. Prefer this over calling
cogl_texture_get_width()
on one of the textures, as that might give a
different size when dealing with subsampling.
since: 13
meta_multi_texture_is_simple
A small function that checks whether the given multi texture uses a “simple”
format, i.e. one that can be represented by a CoglPixelFormat
.
since: 13
meta_multi_texture_to_string
Returns a string representation of multi_texture
, useful for debugging purposes.
since: 13
Signals
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
