Member Function Documentation

virtual KzsGraphicsContextAPI kanzi::GlGraphicsOutput::getGraphicsContextAPI ( ) const

pure virtual

Gets the API used by the associated graphics context.

Returns: Graphics context API.

Implemented in kanzi::DefaultGlGraphicsOutput.

virtual KzsSurfaceType kanzi::GlGraphicsOutput::getSurfaceType ( ) const

pure virtual

Gets the type of the associated graphics surface.

Returns: Surface type.

Implemented in kanzi::DefaultGlGraphicsOutput.

virtual SurfaceColorSpace kanzi::GlGraphicsOutput::getColorSpace ( ) const

pure virtual

Gets the color space used by the associated graphics context.

Returns: Color Space

Implemented in kanzi::DefaultGlGraphicsOutput.

virtual kzsGLProcPointer kanzi::GlGraphicsOutput::getProcAddress ( string_view functionName )

pure virtual

Gets pointer to graphics API function.

Parameters

functionName Name of the function.

Returns: Pointer to the function, or null if not found.

Implemented in kanzi::DefaultGlGraphicsOutput.

virtual void kanzi::GlGraphicsOutput::activate ( )

pure virtual

Makes the graphics output active for the current thread.

Implemented in kanzi::DefaultGlGraphicsOutput.

virtual void kanzi::GlGraphicsOutput::setSwapInterval ( int interval )

pure virtual

Sets the swap interval of the associated graphics implementation.

Parameters

interval Specifies the minimum number of video frame periods per buffer swap. Negative interval values are reserved for platform-specific special cases.

Implemented in kanzi::DefaultGlGraphicsOutput.

virtual void* kanzi::GlGraphicsOutput::getContextHandle ( ) const

pure virtual

Gets the handle of associated graphics context object.

Returns: The handle of associated graphics context object.

virtual void* kanzi::GlGraphicsOutput::createImage	(	void *	context,
		int	target,
		void *	data,
		int *	attributes
	)

pure virtual

Function for creating native image object, which can be shared between client APIs.

Parameters

context	Context to create the image for.
target	Context-specific target specifier.
data	Data to use as image contents.
attributes	Context-specific attributes list.
