Detailed Description

The DynamicShape class represents a mutable shape.

It is provides mutating functions for the SWF::ShapeRecord class that are used in the Flash drawing API. DynamicShape objects are not refcounted, so must be stack-allocated or wrapped in smart pointers.

Member Function Documentation

§ add_line_style()

size_t gnash::DynamicShape::add_line_style ( const LineStyle & stl )

Add a line style, possibly reusing an existing one if existent.

Returns: the 1-based offset of the line style, either added or found. This offset is the one required to properly reference it in gnash::path instances.

References gnash::SWF::Subshape::addLineStyle(), and gnash::SWF::Subshape::lineStyles().

Referenced by lineStyle(), and setBounds().

§ add_path()

void gnash::DynamicShape::add_path ( const Path & pth )

Add a path, updating _currpath and recomputing bounds.

TODO: make private? Only current user is BitmapMovieDefinition. It needs this function unless we provide a mean to add a Bitmap-Filled path

References gnash::SWF::Subshape::addPath(), and gnash::SWF::Subshape::currentPath().

Referenced by beginFill(), gnash::Bitmap::construct(), and shapeRecord().

§ addFillStyle()

size_t gnash::DynamicShape::addFillStyle ( const FillStyle & stl )

Add a fill style, possibly reusing an existing one if existent.

Returns: the 1-based offset of the fill style, either added or found. This offset is the one required to properly reference it in gnash::path instances.

References gnash::SWF::Subshape::addFillStyle(), and gnash::SWF::Subshape::fillStyles().

Referenced by beginFill(), gnash::Bitmap::construct(), and setBounds().

§ beginFill()

void gnash::DynamicShape::beginFill ( const FillStyle & f )

Start drawing with a solid fill.

References add_path(), addFillStyle(), gnash::SWF::ShapeRecord::addSubshape(), gnash::Path::close(), endFill(), and gnash::SWF::Subshape::paths().

Referenced by gnash::registerMovieClipNative(), and ~DynamicShape().

§ clear()

void gnash::DynamicShape::clear ( )

Remove all paths and style informations.

References gnash::SWF::Subshape::clear(), and gnash::SWF::ShapeRecord::clear().

Referenced by gnash::registerMovieClipNative(), gnash::MovieClip::unloadChildren(), gnash::Bitmap::update(), and ~DynamicShape().

§ curveTo()

void gnash::DynamicShape::curveTo	(	std::int32_t	cx,
		std::int32_t	cy,
		std::int32_t	ax,
		std::int32_t	ay,
		int	swfVersion
	)

Draw a curve from current position to given one using given control points.

References gnash::Path::drawCurveTo(), gnash::SWFRect::expand_to_circle(), gnash::Path::expandBounds(), gnash::SWF::ShapeRecord::getBounds(), gnash::SWF::Subshape::lineStyles(), gnash::SWF::ShapeRecord::setBounds(), and gnash::Path::size().

Referenced by gnash::registerMovieClipNative(), and ~DynamicShape().

§ display()

void gnash::DynamicShape::display	(	Renderer &	renderer,
		const Transform &	xform
	)		const

Display a DynamicShape object.

References gnash::Renderer::drawShape().

Referenced by gnash::Bitmap::display(), gnash::MovieClip::draw(), and setBounds().

§ endFill()

void gnash::DynamicShape::endFill ( )

Close an existing filled path, if any.

References gnash::SWF::ShapeRecord::addSubshape(), gnash::Path::ap, gnash::Path::close(), gnash::SWF::Subshape::paths(), gnash::geometry::Point2d::x, and gnash::geometry::Point2d::y.

Referenced by beginFill(), gnash::registerMovieClipNative(), and ~DynamicShape().

§ finalize()

void gnash::DynamicShape::finalize ( ) const

Always call this function before displaying !

It will take care of cleaning up the drawing and setting up correct fill styles
