Constructor & Destructor Documentation

ScreenShotter() [1/2]

gnash::ScreenShotter::ScreenShotter	(	const std::string &	fileName,
		int	quality = 100
	)

Create a ScreenShotter with output type selected from filename.

ScreenShotter() [2/2]

gnash::ScreenShotter::ScreenShotter	(	std::string	fileName,
		FileType	f,
		int	quality = 100
	)

Create a ScreenShotter, specifying the output type.

Member Function Documentation

last() [1/2]

void gnash::ScreenShotter::last ( const Renderer &  r ) const

inline

To be called on the last frame before exit.

Parameters

r	The renderer to use to render the image. Which frame is last depends on the execution path of the SWF, whether the SWF loops, whether a timeout was requested or a maximum number of advances set. Those conditions are not knowable in advance, so the last frame is a special case.

References gnash::key::r.

last() [2/2]

template<typename Action >

void gnash::ScreenShotter::last ( const Renderer &  r, Action *  t = 0  ) const

inline

To be called on the last frame before exit.

Template Parameters

Action

The functor to call only when a screenshot is due.

Parameters

r	The renderer to use to render the image. Which frame is last depends on the execution path of the SWF, whether the SWF loops, whether a timeout was requested or a maximum number of advances set. Those conditions are not knowable in advance, so the last frame is a special case.

References gnash::key::t.

lastFrame()

void gnash::ScreenShotter::lastFrame ( )

inline

Take a screenshot when the last frame is reached.

now()

void gnash::ScreenShotter::now ( )

inline

Take a screenshot at the next possible moment.

screenShot() [1/2]

void gnash::ScreenShotter::screenShot ( const Renderer &  r, size_t  frameAdvance  )

inline

Takes a screenshot if required.

Called on each advance.

Parameters

frameAdvance	used to check whether a screenshot is required as well as to construct the filename.
r	The renderer to use to render the image.

References gnash::key::r.

screenShot() [2/2]

template<typename Action >

void gnash::ScreenShotter::screenShot ( const Renderer &  r, size_t  frameAdvance, Action *  t = 0  )

inline

Takes a screenshot if required.

Called on each advance, invoking a functor before any screenshot is taken.

Template Parameters

Action

The functor to call only when a screenshot is due.

Parameters

frameAdvance	used to check whether a screenshot is required as well as to construct the filename.
r	The renderer to use to render the image.

References gnash::key::r, setFrames(), and gnash::key::t.

setFrames()

void gnash::ScreenShotter::setFrames

(

const FrameList &

frames

)

Request a list of frames to be rendered to image files.
