PNGArt::~PNGArt ( )

If a PNG resource has been loaded it deletes it.

Member Function Documentation

void PNGArt::Delete ( )

virtual

Deletes the PNG resource, this is done automatically when this class is destroyed

Implements IArt.

void PNGArt::Draw	(	IGraphicsPort *	gPort,
		const PMMatrix &	imMatrix,
		int32	agmflags
	)

virtual

Draw's the PNG to the supplied graphics port

Parameters

IGraphicsPort,:	IGraphicsPort to draw to
PMMatrix,:	Transformation matrix to apply to the PNG, if no translation is desired use the idenity matrix or just a plain PMMatrix.
agmflags,:	Any desired AGM flags, use 0 if none are desired.

Implements IArt.

void PNGArt::DrawDisabled	(	IGraphicsPort *	gPort,
		const PMMatrix &	imMatrix,
		int32	agmflags
	)

virtual

Draw's the PNG with a 50% transparensy see regular draw methode for more info.

Implements IArt.

AGMImageRecord* PNGArt::GetBitmap ( ) const

virtual

Returns: A pointer to the AGMImageRecord for the loaded PNG resource

Implements IArt.

int PNGArt::GetHeight ( ) const

virtual

Returns: The height of the loaded PNG resource

Implements IArt.

int PNGArt::GetWidth ( ) const

virtual

Returns: The width of the loaded PNG resource

Implements IArt.

bool PNGArt::HasAlpha ( )

virtual

Does the PNG have a a alpha?

Returns: true if PNG contains pixels not totally opaque

Implements IArt.

bool PNGArt::IsLoaded ( )

virtual

Did the PNG sucessfully load?

Returns: true if loaded

Implements IArt.

static void PNGArt::ReleasePNGSharedCaches ( void )

static

Different instantiations of PNGArt may share a cached PNG reader. ReleaseCaches can be called to free these caches.

bool PNGArt::SetFile	(	const IDFile &	idFile,
		const float	scaleFactor = `1.0`,
		const float	iconScale = `2.0`
	)

virtual

Deletes any currently loaded resource and loads a PNG image file resource in from the supplied file.

Parameters

path	to a PNG file
float	scale factor at which image should be displayed.
float	scale of the icon.

Returns: true if file / resource was loaded

Implements IArt.

bool PNGArt::SetRsrc	(	const PluginID &	pid,
		const RsrcID &	rid,
		const bool	isRollOver,
		const bool	isDark = `false`,
		const float	scaleFactor = `1.0`,
		const float	iconScale = `2.0`
	)

virtual

Deletes any currently loaded resource and loads a PNG image from a plugin's resource. This is the preferred approach.

Parameters

PluginID,:	PluginId to load the resource from
RsrcID,:	Resource ID of the PNG
bool,:	Rollover resource? If false, then a resource type of "PNGA" will be loaded, else a resource type of "PNGR" will be loaded.
bool,:	Dark UI resource? If false, then a resource type of "PNGA" (or "PNGR" if isRollover is true) will be loaded, else a resource type of "PNGD" (or "PNGK" if isRollover is true) will be loaded. Default is false.
float	scale factor at which image should be displayed.
float	scale of the icon.

Returns: true if file / resource was loaded

Implements IArt.
