Detailed Description

Windows-specific class to predefine devices.

Library: winviews
This class defines devices that are specific to Windows. The drawing methods of the superclass (IlvSystemPort) are used without modification.

Since the IlvPort::setTransformer() method is directly built on the Windows API that is common to Windows NT/7/8/10 and Windows 95/98/Me, it is not possible to apply transformations other than translations or scalings. Other types of transformation should be applied when the draw() method is called for the device. Note that since precision is better on the Windows device, it can be interesting to use two transformations: one that is applied to the device and that only contains translation or scaling factors and the other one that is applied when draw() is invoked.

Member Function Documentation

§ clip() [1/2]

virtual void IlvWindowsVirtualDevice::clip ( const IlvRect * rect ) const

virtual

Limits the drawing to the given rectangular area.

Limits the drawing to the rect area. This area maps out a temporary clipping area. These settings will be erased when a new clip function is called.

Parameters

rect	The drawing rectangle.

Reimplemented from IlvSystemPort.

§ clip() [2/2]

virtual void IlvWindowsVirtualDevice::clip ( const IlvRegion * region ) const

virtual

Limits the drawing to the given region.

Limits the drawing to the region region. This area maps out a temporary clipping area. These settings will be erased when a new clip function is called.

Parameters

region The drawing region.

Reimplemented from IlvSystemPort.

§ end()

virtual void IlvWindowsVirtualDevice::end ( )

virtual

Ends the dump devices.

This member function closes the dump devices and does all the necessary cleaning operations. If you redefine this function in subclasses, do the following:

Call the method end() of the superclass.
Remove and destroy the specific data.

Reimplemented from IlvSystemPort.

Reimplemented in IlvWindowsDevice.

§ fillRectangle()

virtual void IlvWindowsVirtualDevice::fillRectangle	(	const IlvPalette *	palette,
		const IlvRect &	rect
	)		const

virtual

Fills the given rectangle.

Fills the rectangle specified by rect.

Parameters

palette	The palette to use for the fill color of the rectangle.
rect	The rectangle to fill.

Reimplemented from IlvSystemPort.

§ getCompatibility()

IlUInt IlvWindowsVirtualDevice::getCompatibility ( ) const

Gets the compatible version of the dump device.

Returns: The current version with which the dump device is compatible. The default value is 220 (corresponding to version 2.2). This insures that the computation of the transformers is coherent with the Postscript dump mecanism. If this value is strictly less than 220, then it is compatible with version 2.1.

§ getHDC()

HDC IlvWindowsVirtualDevice::getHDC ( ) const

Gets the Windows HDC (Handle Device Context).

Returns: The HDC handle associated with the object.

§ getMapMode()

int IlvWindowsVirtualDevice::getMapMode ( ) const

Gets the mapping mode.

Returns: The current mapping mode of the Windows device.

§ initDevice()

virtual IlBoolean IlvWindowsVirtualDevice::initDevice	(	const char *	filename,
		IlvRect *	clip = `0`
	)

virtual

Initializes the dump device.

Initializes the dump device so that it writes its result in the filename file. This member function must be called before any other class member function. The region to be dumped is clipped by the bbox parameter. This member function sets the global clip with bbox set as the parameter to be used throughout the device lifespan.

Parameters

filename	Is usually used to indicate the output filename of the dump.
clip	The clipping rectangle to be used when drawing.

Reimplemented from IlvSystemPort.

Reimplemented in IlvWindowsDevice.

§ isADevice()

virtual IlBoolean IlvWindowsVirtualDevice::isADevice ( ) const

virtual

Queries the nature of this port.

Returns: Always IlTrue.

Reimplemented from IlvPort.

§ isBad()

virtual IlBoolean IlvWindowsVirtualDevice::isBad ( ) const

virtual

Indicates whether this port is valid.

Indicates whether the display system can allocate the system-dependent part of the IlvPort. You must not use this port if it is "bad".

Returns: IlTrue if the display system can not allocate the system-dependent part of the IlvPort.

Reimplemented from IlvSystemPort.

§ newPage()

virtual IlBoolean IlvWindowsVirtualDevice::newPage ( ) const

virtual

Produces an output page and prepares for a new page.

Produces an output page and prepares the dump device for a new page. If there has been an error, you should stop producing output data.

Returns: IlFalse if there has been an error.

Reimplemented from IlvSystemPort.

Reimplemented in IlvWindowsDevice.

§ setCompatibility()

void IlvWindowsVirtualDevice::setCompatibility ( IlUInt version )

Sets compatible version of the dump device.

Sets version as the new version with which the dump device is compatible.

Parameters

version The version to set.

§ setHDC()

void IlvWindowsVirtualDevice::setHDC ( HDC hdc )

Sets the Windows HDC (Handle Device Context).

Sets the hdc parameter as the HDC attribute of the object.

Parameters

hdc	The `HDC` handle to associate with the object.

§ setMapMode()

void IlvWindowsVirtualDevice::setMapMode ( int mode )

Sets the mapping mode.

Sets mode as the new mapping mode of the Windows device.

Parameters

mode	The mapping mode to be set.

§ setTransformer()

virtual void IlvWindowsVirtualDevice::setTransformer ( const IlvTransformer & t )

virtual

Applies another transformer to the coordinates provided for the drawing functions.

Parameters

t	The transformer that is applied.

Reimplemented from IlvSystemPort.
