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

Accessors

Accessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods IlvValueInterface::queryValue(), IlvValueInterface::queryValues(), IlvValueInterface::changeValue(), IlvValueInterface::changeValues(). This class inherits the accessors of its superclass IlvGraphicHandle and adds the following ones:

Name Type Equivalent methods
maximumSize UInt getMaximumSize(), setMaximumSize()
internalColor Color getInternalColor(), setInternalColor()
filterName String getFilterName(), setFilterName()
refreshMode RefreshMode getRefreshMode(), setRefreshMode()
displayMode DisplayMode getDisplayMode(), setDisplayMode()

Member Enumeration Documentation

§ 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.

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

Constructor.

Initializes a new IlvFilteredGraphic.

Parameters
displayThe display.
objectThe referenced object.
filterThe name of the filter flow to apply.
ownerMust be set to IlTrue to make the handle object the owner of the referenced object.

§ ~IlvFilteredGraphic()

virtual IlvFilteredGraphic::~IlvFilteredGraphic ( )
virtual

Destructor.

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

Member Function Documentation

§ applyTransform()

void IlvFilteredGraphic::applyTransform ( const IlvTransformer t)
virtual

Applies a transformation.

Parameters
tThe transformer that is applied to the referenced graphic object by calling its IlvGraphic::applyTransform() member function.

Reimplemented from IlvGraphicHandle.

§ boundingBox()

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.

Parameters
bboxThe bounding box to be set.
tA transformer value or 0 if there is no transformation.

Reimplemented from IlvGraphicHandle.

§ computeBitmapData()

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

Computes the filtered bitmap data.

Parameters
tThe transformer to use.

§ contains()

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
pThe point to be tested.
tpThe transformed point obtained by applying the transformer t to the point p.
tA 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.

§ draw()

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.

Parameters
dstThe destination port this object is drawn onto.
tThe transformer value. If 0, no transformation is performed.
clipThe clipping region, relative to the transformed object, or 0 if none.

Reimplemented from IlvGraphicHandle.

§ getDisplayMode()

DisplayMode IlvFilteredGraphic::getDisplayMode ( ) const

Returns the display mode.

Returns
The display mode.

§ getFilterFlow()

IlvFilterFlow* IlvFilteredGraphic::getFilterFlow ( ) const

Returns the filter flow used.

Returns
The filter flow used.

§ getFilterName()

const IlString& IlvFilteredGraphic::getFilterName ( ) const

Returns the name of the filter used.

Returns
The name of the filter used.

§ getInternalBitmapData()

const IlvBitmapData* IlvFilteredGraphic::getInternalBitmapData ( ) const

Returns the internal filtered bitmap data.

Returns
The internal filtered bitmap data.

§ getInternalColor()

IlvColor* IlvFilteredGraphic::getInternalColor ( ) const

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

Returns
The internal color.

§ getMaximumSize()

IlUInt IlvFilteredGraphic::getMaximumSize ( ) const

Returns the maximum dimension of the internal bitmap.

Returns
The maximum dimension.

§ getRefreshMode()

RefreshMode IlvFilteredGraphic::getRefreshMode ( ) const

Returns the refresh mode.

Returns
The refresh mode.

§ inside()

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.

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

Parameters
rThe region to be tested.
tA 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 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.

§ intersects()

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

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

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

Parameters
rThe region to be tested.
tA 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.

§ invert()

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
tempIf IlTrue, highlights the object.
