Destructor.

Since:
3.0, DALi version 1.1.43
Dali::FrameBuffer::FrameBuffer ( const FrameBuffer &  handle)

Copy constructor, creates a new handle to the same object.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]handleHandle to an object
Dali::FrameBuffer::FrameBuffer ( Internal::FrameBuffer *  pointer) [explicit]

The constructor.

Note:

Since:
3.0, DALi version 1.1.43
Parameters:
[in]pointerA pointer to a newly allocated FrameBuffer

Member Function Documentation

void Dali::FrameBuffer::AttachColorTexture ( Texture &  texture)

Attach the base LOD of a 2D texture to the framebuffer for color rendering.

Note:
This causes a color attachment to be added.
Since:
3.0, DALi version 1.1.43
Parameters:
[in]textureThe texture that will be used as output when rendering
Note:
The texture has to have the same size than the FrameBuffer otherwise it won't be attached.
void Dali::FrameBuffer::AttachColorTexture ( Texture &  texture,
uint32_t  mipmapLevel,
uint32_t  layer 
)

Attach a texture to the framebuffer for color rendering.

Note:
This causes a color attachment to be added.
Since:
3.0, DALi version 1.1.43
Parameters:
[in]textureThe texture that will be used as output when rendering
[in]mipmapLevelThe mipmap of the texture to be attached
[in]layerIndicates which layer of a cube map or array texture to attach. Unused for 2D textures
Note:
The specified texture mipmap has to have the same size than the FrameBuffer otherwise it won't be attached.
static FrameBuffer Dali::FrameBuffer::DownCast ( BaseHandle  handle) [static]

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

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

Gets the color texture used as output in the FrameBuffer.

Since:
3.0, DALi version 1.1.43
Returns:
A handle to the texture used as color output, or an uninitialized handle
static FrameBuffer Dali::FrameBuffer::New ( uint32_t  width,
uint32_t  height,
uint32_t  attachments 
) [static]

Creates a new FrameBuffer object.

Since:
3.0, DALi version 1.1.43
Parameters:
[in]widthThe width of the FrameBuffer
[in]heightThe height of the FrameBuffer
[in]attachmentsThe attachments comprising the format of the FrameBuffer (the type is int to allow multiple bitmasks to be ORd)
Returns:
A handle to a newly allocated FrameBuffer
FrameBuffer& Dali::FrameBuffer::operator= ( const FrameBuffer &  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
