	)		`[virtual]`

Bracket the displaying of a frame from a movie.

Set up to render a full frame from a movie and fills the background. Sets up necessary transforms, to scale the movie to fit within the given dimensions. Call end_display() when you're done. Most of the arguments are only for the ogl renderer. See documentation in that class. Do not use these arguments for new renderers!

Implements gnash::Renderer.

void gnash::renderer::DirectFB::Renderer_DirectFB::begin_submit_mask ( ) [virtual]

Masks

Masks are defined by drawing calls enclosed by begin_submit_mask() and end_submit_mask(). Between these two calls, no drawing is to occur. The shapes rendered between the two calls define the visible region of the mask. Graphics that are irrelevant in the context of a mask (lines and fill styles, for example) should be ignored. After use, disable_mask() is called to remove the mask.

Masks may be nested. That is, end_submit_mask() may be followed by a call to begin_submit_mask(). The resulting mask shall be an intersection of the previously created mask. disable_mask() shall result in the disabling or destruction of the last created mask.

Implements gnash::Renderer.

CachedBitmap* gnash::renderer::DirectFB::Renderer_DirectFB::createCachedBitmap ( std::auto_ptr< image::GnashImage > im ) [virtual]

Given an image, returns a pointer to a CachedBitmap class that can later be passed to FillStyleX_bitmap(), to set a bitmap fill style.

std::string gnash::renderer::DirectFB::Renderer_DirectFB::description ( ) const [inline, virtual]

void gnash::renderer::DirectFB::Renderer_DirectFB::drawGlyph	(	const SWF::ShapeRecord &	rec,
		const rgba &	color,
		const SWFMatrix &	mat
	)		`[virtual]`

Draws a glyph (font character).

Glyphs are defined just like shape characters with the difference that they do not have any fill or line styles. Instead, the shape must be drawn using the given color (solid fill). Please note that although the glyph paths may indicate subshapes, the renderer is to ignore that information.

Parameters:

def
mat
color

void gnash::renderer::DirectFB::Renderer_DirectFB::drawLine	(	const std::vector< point > &	coords,

	)		`[virtual]`

Draw a line-strip directly, using a thin, solid line.

Can be used to draw empty boxes and cursors.

an array of 16-bit signed integer coordinates. Even indices (and 0) are x coordinates, while uneven ones are y coordinates.

the number of x-y coordinates (vertices).

		const gnash::Transform &	xform,
		const gnash::SWFRect *	bounds,
		bool	smooth
	)		`[virtual]`

Draws a video frame.

================================================================== Rendering Interface. ================================================================== The frame has already been decoded and is available in RGB format only.

Parameters:

frame	The RGB video buffer frame. Ownership of the buffer is left to the caller.
mat	The SWFMatrix with world coordinates used to retrieve the x and y coordinate of the video object. The scaling of the SWFMatrix only refers to the Flash instance, not to the video inside that instance. When a video object is placed on the stage and the loaded video is smaller, then the SWFMatrix is still an "identity matrix". However, if the video object is scaled via ActionScript, for example, then the SWFMatrix will change. This means the renderer has to find the correct scaling for the video inside the bounds.
bounds	The minX/minY fields of this SWFRect are always zero. The width and height determine the size of the Flash video instance on the stage (in TWIPS) prior to SWFMatrix transformations.

void gnash::renderer::DirectFB::Renderer_DirectFB::end_submit_mask ( ) [virtual]

void gnash::renderer::DirectFB::Renderer_DirectFB::set_invalidated_regions ( const InvalidatedRanges & ) [virtual]

Sets the update region (called prior to begin_display).

================================================================== Prepare drawing area and other utilities ================================================================== The renderer might do clipping and leave the region outside these bounds unchanged, but he is allowed to change them if that makes sense. After rendering a frame the area outside the invalidated region can be undefined and is not used.

It is not required for all renderers. Parameters are world coordinates (TWIPS).

For more info see page Detection of updated regions.

void gnash::renderer::DirectFB::Renderer_DirectFB::set_scale	(	float	,
