Detailed Description

Implements the BitmapData native type.

All functions can be called if the BitmapData has been disposed. Callers do not need to check.

Constructor & Destructor Documentation

gnash::BitmapData_as::BitmapData_as	(	as_object *	owner,
		std::auto_ptr< GnashImage >	im,
		boost::uint32_t	fillColor
	)

Construct a BitmapData.

The constructor sets the fill colour and the immutable size of the bitmap, as well as whether it can handle transparency or not.

Member Function Documentation

void gnash::BitmapData_as::attach ( DisplayObject * obj ) [inline]

Attach this BitmapData to an object.

This may be either as a fill or an attached Bitmap.

const CachedBitmap* gnash::BitmapData_as::bitmapInfo ( ) const [inline]

Referenced by gnash::Bitmap::construct().

void gnash::BitmapData_as::dispose ( )

Free the bitmap data.

bool gnash::BitmapData_as::disposed ( ) const [inline]

Whether the BitmapData has been disposed.

Referenced by gnash::Bitmap::Bitmap(), and getPixel().

void gnash::BitmapData_as::fillRect	(	int	x,
		int	y,
		int	w,
		int	h,
		boost::uint32_t	color
	)

Fill the bitmap with a colour starting at x, y.

Negative values are handled correctly.

References gnash::for_each(), and gnash::DisplayObject::update().

boost::uint32_t gnash::BitmapData_as::getPixel	(	size_t	x,
		size_t	y
	)			const

Returns the value of the pixel at (x, y).

Returns 0 if the pixel is out of range or the image has been disposed.

References gnash::GnashImage::argb_begin(), disposed(), height(), gnash::pixel_iterator< Iterator, Pixel >::toARGB(), and width().

size_t gnash::BitmapData_as::height ( ) const [inline]

Return the height of the image.

Do not call if disposed!

Referenced by getPixel().

void gnash::BitmapData_as::setPixel	(	size_t	x,
		size_t	y,
		boost::uint32_t	color
	)

Set a specified pixel to the specified color.

Retains transparency value for BitmapDatas with transparency.

void gnash::BitmapData_as::setPixel32	(	size_t	x,
		size_t	y,
		boost::uint32_t	color
	)

Set a specified pixel to the specified color.

void gnash::BitmapData_as::setReachable ( ) [virtual]

Overrides Relay::setReachable().

Reimplemented from gnash::Relay.

Referenced by gnash::Bitmap::markReachableObjects().

bool gnash::BitmapData_as::transparent ( ) const [inline]

References gnash::GNASH_IMAGE_RGBA.

size_t gnash::BitmapData_as::width ( ) const [inline]

Return the width of the image.

Do not call if disposed!
