Detailed Description

Extracts the pixels from a graphics::Buffer using GL facilities.

Constructor & Destructor Documentation

mir::scene::GLPixelBuffer::GLPixelBuffer ( std::unique_ptr< graphics::GLContext > gl_context )

mir::scene::GLPixelBuffer::~GLPixelBuffer ( )

noexcept

void const * mir::scene::GLPixelBuffer::as_argb_8888 ( )

virtual

The pixels in 0xAARRGGBB format.

The pixel data is owned by the PixelBuffer object and is only valid until the next call to fill_from().

This method may involve transformation of the extracted data.

void mir::scene::GLPixelBuffer::fill_from ( graphics::Buffer & buffer )

virtual

Fills the PixelBuffer with the contents of a graphics::Buffer.

Parameters

[in] buffer the buffer to get the pixels of

geom::Size mir::scene::GLPixelBuffer::size ( ) const

virtual

The size of the pixel buffer.

geom::Stride mir::scene::GLPixelBuffer::stride ( ) const

virtual

The stride of the pixel buffer.
