information()

Texture::Information Btk::Texture::information

(

)

const

Get the texture's information.

Returns

Information

lock()

void Btk::Texture::lock	(	const Rect *	rect,
		void **	pixels,
		int *	pitch
	)

Lock a Streaming Texture.

Parameters

rect	The area you want to lock(nullptr to all texture)
pixels	The pixels pointer's pointer
pitch	The texture's pixels pitch pointer

size()

Size Btk::Texture::size ( ) const

inline

Get the size(w and h)

Returns

W and H

unlock()

void Btk::Texture::unlock

(

)

Unlock the texture.

update()

void Btk::Texture::update	(	const Rect *	r,
		void *	pixels,
		int	pitch
	)

Update a texture's pixels.

Note

This is a very slow operation

Parameters

r	The area you want to update(nullptr to all texture)
pixels	The pixels pointer
pitch	The pixels pitch
