bool gnash::LineStyle::doPixelHinting

(

)

const [inline]

Return true if pixel hinting should be activated.

CapStyle gnash::LineStyle::endCapStyle

(

)

const [inline]

Return the end cap style.

Referenced by gnash::Renderer_cairo::apply_line_style().

const rgba& gnash::LineStyle::get_color

)

const [inline]

Return line color and alpha.

Referenced by set_lerp(), and gnash::Renderer_cairo::apply_line_style().

boost::uint16_t gnash::LineStyle::getThickness

(

)

const [inline]

Return thickness of the line, in TWIPS.

float gnash::LineStyle::miterLimitFactor

(

Referenced by gnash::Renderer_cairo::apply_line_style().

bool gnash::LineStyle::noClose

(

)

const [inline]

Return true if stroke should not be closed if the stroke's last point matches the first point. Caps should be applied instead of a join

void gnash::LineStyle::read	(	SWFStream &	in,
		SWF::TagType	t,
		movie_definition &	md,
		const RunResources &	r
	)

Read the line style from an SWF stream.

Stream is assumed to be positioned at the right place.

Throw a ParserException if there's no enough bytes in the currently opened tag for reading. See stream::ensureBytes()

void gnash::LineStyle::read_morph	(	SWFStream &	in,
		SWF::TagType	t,
		movie_definition &	md,
		const RunResources &	r,
		LineStyle *	pOther
	)

Read two lines styles from the SWF stream at the same time -- this is used in morphing.

bool gnash::LineStyle::scaleThicknessHorizontally

(

)

const [inline]

Return true if line thickness should be scaled horizontally.

Referenced by gnash::Renderer_cairo::apply_line_style().

bool gnash::LineStyle::scaleThicknessVertically

(

)

const [inline]

Return true if line thickness should be scaled vertically.

Referenced by gnash::Renderer_cairo::apply_line_style().

void gnash::LineStyle::set_lerp	(	const LineStyle &	ls1,
		const LineStyle &	ls2,
		float	ratio
	)

Set this style to the interpolation of the given one.

Parameters:

ls1	First LineStyle to interpolate.
ls2	Second LineStyle to interpolate. The interpolation factor (0..1). When 0, this will be equal to ls1, when 1 this will be equal to ls2.

CapStyle gnash::LineStyle::startCapStyle

(

)

const [inline]

Return the start cap style.
