Member Function Documentation

◆ setSize()

bool OpenGL::Backbuffer::setSize ( uint  width,
uint  height,
Common::RotationMode  rotation 
)
overridevirtual

Set the size of the back buffer.

Implements OpenGL::Framebuffer.

◆ activateInternal()

void OpenGL::Backbuffer::activateInternal ( )
overrideprotectedvirtual

Activate framebuffer.

This is supposed to set all state associated with the framebuffer.

Implements OpenGL::Framebuffer.

Reimplemented in LibretroHWFramebuffer.
