Member Function Documentation

beginFrame()

virtual void VideoContext::beginFrame ( )

pure virtual

Called at the beginning of every frame to begin it.

Implemented in aurore::HeadlessVideoContext.

clear()

virtual void VideoContext::clear ( NVGcolor  color )

pure virtual

Called at the beginning of every frame to clear the window

Implemented in aurore::HeadlessVideoContext.

endFrame()

virtual void VideoContext::endFrame ( )

pure virtual

Called at the end of every frame to end it (swap buffers...).

Implemented in aurore::HeadlessVideoContext.

fullScreen()

virtual void VideoContext::fullScreen ( bool  fs )

inlinevirtual

getCurrentMonitorIndex()

virtual int VideoContext::getCurrentMonitorIndex ( )

inlinevirtual

getNVGContext()

virtual NVGcontext * VideoContext::getNVGContext ( )

pure virtual

Implemented in aurore::HeadlessVideoContext.

getScaleFactor()

virtual double VideoContext::getScaleFactor ( )

pure virtual

Implemented in aurore::HeadlessVideoContext.

readPixels()

virtual bool VideoContext::readPixels ( std::vector< unsigned char > *  rgba, int *  width, int *  height  )

inlinevirtual

Reads back the frame drawn so far (before endFrame() presents it): top-down rows of opaque RGBA pixels, at the drawable's size. Returns false where the driver cannot (only the OpenGL ones do for now).

Reimplemented in aurore::HeadlessVideoContext.

resetState()

virtual void VideoContext::resetState ( )

pure virtual

Can be called by the application to reset the graphics state, in case there is a need to use the graphics API directly (for instance direct OpenGL calls).

Implemented in aurore::HeadlessVideoContext.

setSwapInterval()

virtual void VideoContext::setSwapInterval ( int  interval )

pure virtual

Implemented in aurore::HeadlessVideoContext.
