Member Function Documentation

void pdfobjects::CPageDisplay::createXpdfDisplayParams	(	boost::shared_ptr< GfxResources > &	res,
		boost::shared_ptr< GfxState > &	state
	)

Creates xpdf's state and resource parameters.

void pdfobjects::CPageDisplay::displayPage	(	::OutputDev &	out,
		boost::shared_ptr< CDict >	pagedict,
		int	x = `-1`,
		int	y = `-1`,
		int	w = `-1`,
		int	h = `-1`
	)

Draws page using specified page dictionary on an output device with last used display parameters.

Parameters:

	out	Output device.
	dict	If not null, page is created from dict otherwise this page dictionary is used. But still some information is gathered from this page dictionary.

void pdfobjects::CPageDisplay::displayPage	(	::OutputDev &	out,
		int	x = `-1`,
		int	y = `-1`,
		int	w = `-1`,
		int	h = `-1`
	)

Draws page on an output device. Use old display params.

libs::Rectangle pdfobjects::CPageDisplay::getMediabox ( ) const

Returns media box of this page.

It is a required item in page dictionary (spec p.119) but can be inherited from a parent in the page tree.

Returns:: Rectangle specifying the box.

libs::Rectangle pdfobjects::CPageDisplay::getPageRect ( ) const

Returns rect of this page.

int pdfobjects::CPageDisplay::getRotation ( ) const

Returns rotation in degrees.

References _page, pdfobjects::CPageAttributes::InheritedAttributes::_rotate, pdfobjects::CPageAttributes::fillInherited(), and pdfobjects::CPage::getDictionary().

void pdfobjects::CPageDisplay::setDisplayParams ( const DisplayParams & dp )

Sets display params.

void pdfobjects::CPageDisplay::setMediabox ( const libs::Rectangle & rc )

Sets media box of this page.

Parameters:

rc

Rectangle for the media box.

As a side effect it changes also CropBox and TrimBox if they are set.

void pdfobjects::CPageDisplay::setRotation ( int rot )

Sets rotation in degrees.

References _page, pdfobjects::CPage::getDictionary(), and pdfobjects::Specification::Page::ROTATE.

void pdfobjects::CPageDisplay::setTransformMatrix ( double tm[6] )

Sets transform matrix of a page. This operator will be preceding first cm operator (see pdf specification), if not found it will be the first operator.

Parameters:

tm

Six number representing transform matrix.
