Detailed Description

Graphic class.

Library: views

This section explains the concept of filtered objects. An IlvFilteredGraphic object is used to reference an IlvGraphic object. The IlvFilteredGraphic renders internally the referenced object, and then applies a bitmap filter on it.

See Also: IlvBitmapFilter, IlvGraphicHandle

Member Enumeration Documentation

enum IlvFilteredGraphic::DisplayMode

This enumeration defines the possible values for the display mode.

See Also: IlvFilteredGraphic::setDisplayMode, IlvFilteredGraphic::getDisplayMode

Enumerator
DisplayFiltered	The filtered graphic is displayed. This mode is the default display mode.
DisplayShowThrough	The referenced graphic is displayed.

enum IlvFilteredGraphic::RefreshMode

This enumeration defines the possible values for the refresh mode.

See Also: IlvFilteredGraphic::setRefreshMode, IlvFilteredGraphic::getRefreshMode

Enumerator
RefreshOnDemand	The filtered graphic is recomputed only if requested.
RefreshAlways	The filtered graphic is recomputed for each transformation request. This is the default refresh mode.

Constructor & Destructor Documentation

IlvFilteredGraphic::IlvFilteredGraphic	(	IlvDisplay *	display,
		IlvGraphic *	object,
		const IlString &	filter = `""`,
		IlBoolean	owner = `IlFalse`
	)

Constructor.

Initializes a new IlvFilteredGraphic.

Parameters

display	The display.
object	The referenced object.
filter	The name of the filter flow to apply.
owner	Must be set to `IlTrue` to make the handle object the owner of the referenced object.

virtual IlvFilteredGraphic::~IlvFilteredGraphic ( )

virtual

Destructor.

The destructor releases all the memory used by the instance. It unlocks the filter.

Member Function Documentation

void IlvFilteredGraphic::applyTransform ( const IlvTransformer * t )

virtual

Applies a transformation.

Parameters

t	The transformer that is applied to the referenced graphic object by calling its `IlvGraphic::applyTransform` member function.

Reimplemented from IlvGraphicHandle.

void IlvFilteredGraphic::boundingBox	(	IlvRect &	bbox,
		const IlvTransformer *	t = `0`
	)		const

virtual

Retrieves the bounding box of the graphic object.

Sets bbox, the rectangle reference parameter, to be the bounding box of the object. Since the object can appear within a transformed environment (for example, in a multiview editor), an IlvTransformer object occurs as an optional parameter in order to compute the bounding box in the coordinate system of the transformed environment. When there is no transformation, t is set to 0.

Parameters

bbox	The bounding box to be set.
t	A transformer value or `0` if there is no transformation.

Reimplemented from IlvGraphicHandle.

void IlvFilteredGraphic::computeBitmapData ( const IlvTransformer * t = 0 )

Computes the filtered bitmap data.

Parameters

t	The transformer to use.

virtual IlBoolean IlvFilteredGraphic::contains	(	const IlvPoint &	p,
		const IlvPoint &	tp,
		const IlvTransformer *	t = `0`
	)		const

virtual

Checks whether a point is in the object.

Checks whether the coordinates are located in the shape of this object. A transformation parameter allows you to use the view's coordinate system for this test.

Parameters

p	The point to be tested.
tp	The transformed point obtained by applying the transformer t to the point p.
t	A transformer value, or `0` if there is no transformation.

Returns: IlTrue when the point p lies inside the outline of the object.

Reimplemented from IlvGraphicHandle.

void IlvFilteredGraphic::draw	(	IlvPort *	dst,
		const IlvTransformer *	t = `0`,
		const IlvRegion *	clip = `0`
	)		const

virtual

Draws the graphic object.

Draws the object in the given IlvPort using the transformer t which might have the value 0. The clip parameter, which can also be 0, represents the clipping region relative to the transformed object.

Parameters

dst	The destination port.
t	The transformer value. If 0, no transformation is performed.
clip	The clipping region, or 0 if none.

Reimplemented from IlvGraphicHandle.

DisplayMode IlvFilteredGraphic::getDisplayMode ( ) const

Returns the display mode.

Returns: The display mode.

IlvFilterFlow* IlvFilteredGraphic::getFilterFlow ( ) const

Returns the filter flow used.

Returns: The filter flow used.

const IlString& IlvFilteredGraphic::getFilterName ( ) const

Returns the name of the filter used.

Returns: The name of the filter used.

const IlvBitmapData* IlvFilteredGraphic::getInternalBitmapData ( ) const

Returns the internal filtered bitmap data.

Returns: The internal filtered bitmap data.

IlvColor* IlvFilteredGraphic::getInternalColor ( ) const

Returns the color used internally to compute the mask from the object.

Returns: The internal color.

IlUInt IlvFilteredGraphic::getMaximumSize ( ) const

Returns the maximum dimension of the internal bitmap.

Returns: The maximum dimension.

RefreshMode IlvFilteredGraphic::getRefreshMode ( ) const

Returns the refresh mode.

Returns: The refresh mode.

virtual IlBoolean IlvFilteredGraphic::inside	(	const IlvRegion &	r,
		const IlvTransformer *	t = `0`
	)		const

virtual

Determines whether an object with transformation applied is inside the bounding box.

Parameters

r	The region to be tested.
t	A transformer value, or `0` if there is no transformation.

Returns: IlTrue when the object, drawn with the transformer t, covers completely the region r. This virtual member function returns IlFalse when this is not the case. That means that it returns IlTrue if all rectangles that define the region completely lie inside the object.

Reimplemented from IlvGraphicHandle.

virtual IlBoolean IlvFilteredGraphic::intersects	(	const IlvRegion &	r,
		const IlvTransformer *	t = `0`
	)		const

virtual

Checks whether a region intersects the bounding box with transformation applied.

Parameters

r	The region to be tested.
t	A transformer value, or `0` if there is no transformation.

Returns: IlTrue when the region r overlaps the transformed object (if t is not 0) and IlFalse when this is not the case.

Reimplemented from IlvGraphicHandle.

virtual void IlvFilteredGraphic::invert ( IlBoolean temp = IlFalse )

virtual

Highlights the object.

Highlights the object. It is implemented as swapping the foreground and background colors of the object, but can have other implementations in derived subclasses. The parameter temp controls the way you toggle between the background and the foreground. If temp is omitted or is IlFalse, then a new palette is computed by calling the IlvDisplay::getPalette() method. If temp is IlTrue, the object palette is inverted, and thus all the objects referencing this palette will be affected.

Parameters

temp	If `IlTrue`, highlights the object.

Reimplemented from IlvGraphicHandle.

IlBoolean IlvFilteredGraphic::isInvalid ( ) const

Returns whether the internal filtered graphic is invalid.

Returns: IlTrue if the internal filtered graphic is invalid.

Changing the IlvDrawMode attribute of an object is considered a temporary operation. You have to set the mode to its default value when you no longer need another mode different from the value IlvModeSet. The drawing mode information is passed to the palette of the graphic object (see the IlvPalette::setOverwrite method for more details).

Parameters

mode	The drawing mode to be set.

Reimplemented from IlvGraphicHandle.

virtual void IlvFilteredGraphic::setOverwrite ( IlBoolean over )

virtual

Sets an overwrite mode that modifies how the drawing member functions operate.

Modifies the way the drawing member functions operate. The information is passed to the palette of the graphic object (see the IlvPalette::setOverwrite method for more details).

Parameters

over	If `IlFalse`, sets selective hidden drawing operations.

Reimplemented from IlvGraphicHandle.

virtual void IlvFilteredGraphic::setPalette ( IlvPalette * palette )

virtual

Sets the palette of the object.

Each of the graphic properties of this object is then taken from this IlvPalette instance.

Parameters

palette The palette to be set.

Reimplemented from IlvGraphicHandle.

virtual void IlvFilteredGraphic::setPattern ( IlvPattern * pattern )

virtual

Sets the pattern of the object.

Parameters

pattern The new pattern.

void IlvFilteredGraphic::setRefreshMode ( RefreshMode mode )
