Constructor & Destructor Documentation

pdf::graph::CState::CState

(

)

default constructor. it will ininitalize the members to their PDF default values.

00036     : m_line_width( 1.0f ), m_line_cap( butt_cap ),
00037       m_line_join( mitter_join ), m_miter_limit( 10.0f ),
00038       m_flatness( 1.0f )

pdf::graph::CState::CState	(	double	line_width,
		ECapStyle	line_cap = butt_cap,
		EJoinStyle	line_join = mitter_join,
		double	miter_limit = 10.0f,
		const CDash &	dash = CDash( ),
		double	flatness = 1.0f
	)

constructor initializes all members with parameters.

Parameters:

line_width	width of line is user space
line_cap	a code specifying the shape of the endpoints for any open path that is stroked
line_join	A code specifying the shape of joints between connected segments of a stroked path
miter_limit	the maximum length of mitered line joins for stroked paths
dash	dash pattern. see its reference for details.
flatness	the precision with which curves are to be rendered on the output device.

Member Function Documentation

std::ostream & pdf::graph::CState::Print	(	std::ostream &	os,
		const CState &	prev
	)	const

print the state into an output stream. like CTextState::Print(), this function takes the previous state as parameter. only the difference between the previous state will be printed.

00109     if ( m_line_width != prev.m_line_width )
00110         os << m_line_width  << " w\n" ;
00111     
00112     if ( m_line_colour != prev.m_line_colour )
00113         os << m_line_colour << " RG\n" ;

00115     if ( m_fill_colour != prev.m_fill_colour )
