CoglTexture
Description [src]
abstract class Cogl.Texture : GObject.Object
{
/* No available fields */
}Functions for creating and manipulating textures
Cogl allows creating and manipulating textures using a uniform API that tries to hide all the various complexities of creating, loading and manipulating textures.
Instance methods
cogl_texture_allocate
Explicitly allocates the storage for the given texture which
allows you to be sure that there is enough memory for the
texture and if not then the error can be handled gracefully.
cogl_texture_get_components
Queries what components the given texture stores internally as set
via cogl_texture_set_components().
cogl_texture_get_max_waste
Queries the maximum wasted (unused) pixels in one dimension of a GPU side texture.
cogl_texture_get_premultiplied
Queries the pre-multiplied alpha status for internally stored red,
green and blue components for the given texture as set by cogl_texture_set_premultiplied().
cogl_texture_is_sliced
Queries if a texture is sliced (stored as multiple GPU side tecture objects).
cogl_texture_set_components
Affects the internal storage format for this texture by specifying what components will be required for sampling later.
cogl_texture_set_data
texture a CoglTexture.
Sets all the pixels for a given mipmap level by copying the pixel
data pointed to by the data argument into the given texture.
cogl_texture_set_premultiplied
Affects the internal storage format for this texture by specifying whether red, green and blue color components should be stored as pre-multiplied alpha values.
cogl_texture_set_region
Sets the pixels in a rectangular subregion of texture from an in-memory
buffer containing pixel data.
cogl_texture_set_region_from_bitmap
Copies a specified source region from bitmap to the position
(src_x, src_y) of the given destination texture handle.
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.
