Public Member Functions

 Texture ()
 Default constructor, creates an empty handle.
 ~Texture ()
 Destructor.
 Texture (const Texture &handle)
 Copy constructor, creates a new handle to the same object.
Texture & operator= (const Texture &handle)
 Assignment operator, changes this handle to point at the same object.
bool Upload (PixelData pixelData)
 Uploads data to the texture from a PixelData object.
bool Upload (PixelData pixelData, unsigned int layer, unsigned int mipmap, unsigned int xOffset, unsigned int yOffset, unsigned int width, unsigned int height)
 Uploads data to the texture from a PixelData object.
void GenerateMipmaps ()
 Generates mipmaps for the texture. This will auto generate all the mipmaps for the texture based on the data in the base level.
unsigned int GetWidth () const
 Returns the width of the texture.
unsigned int GetHeight () const
 Returns the height of the texture.
 Texture (Internal::Texture *pointer)
 The constructor.

Static Public Member Functions

static Texture New (TextureType::Type type, Pixel::Format format, unsigned int width, unsigned int height)
 Creates a new Texture object.
static Texture New (NativeImageInterface &nativeImageInterface)
 Creates a new Texture object from a native image.
static Texture DownCast (BaseHandle handle)
 Downcasts to a texture. If not, the returned handle is left uninitialized.

Member Function Documentation

static Texture Dali::Texture::DownCast ( BaseHandle  handle) [static]

Downcasts to a texture. If not, the returned handle is left uninitialized.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]handleHandle to an object
Returns:
Texture handle or an uninitialized handle
void Dali::Texture::GenerateMipmaps ( )

Generates mipmaps for the texture. This will auto generate all the mipmaps for the texture based on the data in the base level.

Since:
3.0, DALi version 1.1.43
unsigned int Dali::Texture::GetHeight ( ) const

Returns the height of the texture.

Since:
3.0, DALi version 1.1.43
Returns:
The height, in pixels, of the texture
unsigned int Dali::Texture::GetWidth ( ) const

Returns the width of the texture.

Since:
3.0, DALi version 1.1.43
Returns:
The width, in pixels, of the texture
static Texture Dali::Texture::New ( TextureType::Type  type,
Pixel::Format  format,
unsigned int  width,
unsigned int  height 
) [static]

Creates a new Texture object.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]typeThe type of the texture
[in]formatThe format of the pixel data
[in]widthThe width of the texture
[in]heightThe height of the texture
Returns:
A handle to a newly allocated Texture
static Texture Dali::Texture::New ( NativeImageInterface &  nativeImageInterface) [static]

Creates a new Texture object from a native image.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]nativeImageInterfaceA native image
Returns:
A handle to a newly allocated Texture
Note:
It is not possible to upload data to textures created from a native image using Upload methods although there might be platform specific APIs to upload data to a native image.
Texture& Dali::Texture::operator= ( const Texture &  handle)

Assignment operator, changes this handle to point at the same object.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]handleHandle to an object
Returns:
Reference to the assigned object
bool Dali::Texture::Upload ( PixelData  pixelData)

Uploads data to the texture from a PixelData object.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]pixelDataThe pixelData object
Returns:
True if the PixelData object has compatible pixel format and fits within the texture, false otherwise
bool Dali::Texture::Upload ( PixelData  pixelData,
unsigned int  layer,
unsigned int  mipmap,
unsigned int  xOffset,
unsigned int  yOffset,
unsigned int  width,
unsigned int  height 
)

Uploads data to the texture from a PixelData object.

Note:
Upload does not upsample or downsample pixel data to fit the specified rectangular area in the texture.
Since:
3.0, DALi version 1.1.43
Parameters:
[in]pixelDataThe pixelData object
[in]layerSpecifies the layer of a cube map or array texture (Unused for 2D textures).
See also:
CubeMapLayer
Parameters:
[in]mipmapSpecifies the level-of-detail number. Level 0 is the base image level. Level n is the nth mipmap reduction image
[in]xOffsetSpecifies an horizontal offset of the rectangular area in the texture that will be updated
[in]yOffsetSpecifies a vertical offset of the rectangular area in the texture that will be updated
[in]widthSpecifies the width of the rectangular area in the texture that will be updated
[in]heightSpecifies the height of the rectangular area in the texture that will be updated
Returns:
True if the PixelData object has compatible pixel format and fits in the rectangle specified, false otherwise
