Detailed Description

Cairo Image class.

TODO ...

Constructor & Destructor Documentation

◆ CairoImage() [1/4]

CairoImage::CairoImage ( )

Constructor for a null Image.

◆ CairoImage() [2/4]

CairoImage::CairoImage	(	const char *	rawData,
		uint	width,
		uint	height,
		ImageFormat	format )

Constructor using raw image data.

Note: rawData must remain valid for the lifetime of this Image.

◆ CairoImage() [3/4]

CairoImage::CairoImage	(	const char *	rawData,
		const Size< uint > &	size,
		ImageFormat	format )

Constructor using raw image data.

Note: rawData must remain valid for the lifetime of this Image.

◆ CairoImage() [4/4]

CairoImage::CairoImage ( const CairoImage & image )

Constructor using another image data.

◆ ~CairoImage()

CairoImage::~CairoImage ( )

override

Destructor.

Member Function Documentation

◆ loadFromMemory()

void CairoImage::loadFromMemory	(	const char *	rawData,
		const Size< uint > &	size,
		ImageFormat	format = kImageFormatBGRA )

overridevirtualnoexcept

Load raw image data from memory.

Note: rawData must remain valid for the lifetime of this Image.

Reimplemented from ImageBase.

◆ loadFromPNG()

void CairoImage::loadFromPNG	(	const char *	pngData,
		uint	dataSize )

noexcept

Load PNG image from memory. Image size is read from PNG contents.

Note: pngData must remain valid for the lifetime of this Image.

◆ drawAt()

void CairoImage::drawAt	(	const GraphicsContext &	context,
		const Point< int > &	pos )

overridevirtual

Draw this image at position pos using the graphics context context.

Implements ImageBase.

◆ getSurface()

cairo_surface_t * CairoImage::getSurface ( ) const

inlinenoexcept

Get the cairo surface currently associated with this image. FIXME might be removed

◆ operator=()

CairoImage & CairoImage::operator= ( const CairoImage & image )
