Member Function Documentation

◆ setupScreen()

virtual void Grim::GfxBase::setupScreen	(	int	screenW,
		int	screenH
	)

pure virtual

Creates a render-context.

Parameters

screenW	the width of the context
screenH	the height of the context

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ isHardwareAccelerated()

virtual bool Grim::GfxBase::isHardwareAccelerated ( )

pure virtual

Query whether the current context is hardware-accelerated

Returns: true if hw-accelerated, false otherwise

Implemented in Grim::GfxTinyGL, and Grim::GfxOpenGLS.

◆ supportsShaders()

virtual bool Grim::GfxBase::supportsShaders ( )

pure virtual

Query whether the current context supports shaders

Returns: true if supports shaders, false otherwise

Implemented in Grim::GfxTinyGL, and Grim::GfxOpenGLS.

◆ flipBuffer()

virtual void Grim::GfxBase::flipBuffer ( bool opportunistic = false )

pure virtual

Swap the buffers, making the drawn screen visible

Parameters

opportunistic True when the flip can be avoided to spare CPU

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ getScreenBoundingBox()

virtual void Grim::GfxBase::getScreenBoundingBox	(	const Mesh *	mesh,
		int *	x1,
		int *	y1,
		int *	x2,
		int *	y2
	)

pure virtual

FIXME: The implementations of these functions (for Grim and EMI, respectively) are very similar. Needs refactoring. See issue #789.

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ createBitmap()

virtual void Grim::GfxBase::createBitmap ( BitmapData * bitmap )

pure virtual

Prepares a bitmap for drawing performs any format conversions needed for the renderer, and might create an internal representation of the bitmap external changes to the bitmap may not be visible after this is called. Must be called before drawBitmap can be used.

the external bitmap might have its data changed by this function,

Parameters

bitmap the bitmap to be prepared

See also: destroyBitmap; drawBitmap

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ drawBitmap()

virtual void Grim::GfxBase::drawBitmap	(	const Bitmap *	bitmap,
		int	x,
		int	y,
		uint32	layer = `0`
	)

pure virtual

Draws a bitmap before this is safe to use, createBitmap MUST have been called

Parameters

bitmap the bitmap to be drawn

See also: createBitmap; destroyBitmap

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ destroyBitmap()

virtual void Grim::GfxBase::destroyBitmap ( BitmapData * bitmap )

pure virtual

Deletes any internal references and representations of a bitmap after this is called, it is safe to dispose of or change the external bitmapdata.

Parameters

bitmap the bitmap to be destroyed

See also: createBitmap; drawBitmap

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ dimScreen()

virtual void Grim::GfxBase::dimScreen ( )

pure virtual

Dims the entire screen Sets the entire screen to 10% of its current brightness, and converts it to grayscale.

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ irisAroundRegion()

virtual void Grim::GfxBase::irisAroundRegion	(	int	x1,
		int	y1,
		int	x2,
		int	y2
	)

pure virtual

Draw a completely opaque Iris around the specified rectangle. the arguments specify the distance from the screen-edge to the first non-iris pixel.

Parameters

x	the width of the Iris
y	the height of the Iris

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ prepareMovieFrame()

virtual void Grim::GfxBase::prepareMovieFrame ( Graphics::Surface * frame )

pure virtual

Prepare a movie-frame for drawing performing any necessary conversion

Parameters

width	the width of the movie-frame.
height	the height of the movie-frame.
bitmap	a pointer to the data for the movie-frame.

See also: drawMovieFrame; releaseMovieFrame

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.

◆ releaseMovieFrame()

virtual void Grim::GfxBase::releaseMovieFrame ( )

pure virtual

Release the currently prepared movie-frame, if one exists.

See also: drawMovieFrame; prepareMovieFrame

Implemented in Grim::GfxOpenGLS, and Grim::GfxTinyGL.
