Constructor & Destructor Documentation

gnash::cxform::cxform

(

)

Initialize to the identity color transform (no transform).

Member Function Documentation

void gnash::cxform::concatenate

(

const cxform &

c

)

Concatenate cxform c onto ours.

When transforming colors, c's transform is applied first, then ours.

References aa, ab, ba, bb, ga, gb, ra, and rb.

Referenced by gnash::DisplayObject::get_world_cxform().

bool gnash::cxform::is_identity

(

)

const

Returns true when the cxform equals identity (no transform).

bool gnash::cxform::is_invisible

(

)

const

Returns true when the cxform leads to alpha == 0.

Not the _alpha property, but the visible alpha related to dislpay. The two might be completely diffrent. eg. mc._alpha ranges in [-32768, 32767] But the alpha on screen ranges in [0, 255]

cxform& gnash::cxform::load_from

(

float *

src

)

[inline]

Load an cxform record from an external array.

References s2x::f.

void gnash::cxform::read_rgb

(

SWFStream &

in

)

Read RGB from the SWF input stream.

Referenced by gnash::SWF::ButtonRecord::readRGBTransform().

void gnash::cxform::read_rgba

(

SWFStream &

in

)

Read RGBA from the SWF input stream.

Referenced by gnash::SWF::ButtonRecord::read().

void gnash::cxform::store_to

(

boost::int16_t *

dst

)

const [inline]

Store the cxform record to an external array.

std::string gnash::cxform::toString

(

)

const

void gnash::cxform::transform	(	boost::uint8_t &	r,
		boost::uint8_t &	g,
		boost::uint8_t &	b,
		boost::uint8_t &	a
	)			const

Transform the given color.

rgba gnash::cxform::transform

(

const rgba &

in

)

const

Transform the given color, return the result.
