Detailed Description

template<class T>
class lti::patternDraw< T >

Object for drawing lines and points in a lti::matrix with support for line and fill patterns.

This means that drawing lines and filled areas is a little slower than the methods of the draw class.

		const int	r,
		const bool &	filled = false
	)			[virtual]

draw a circle with circle center 'p1' and radius 'r'

Reimplemented from lti::draw< T >.

const char* lti::patternDraw< T >::getTypeName

(

)

const [virtual]

get name of this type

Reimplemented from lti::draw< T >.

template<class T >

void lti::patternDraw< T >::horizontalLine	(	const int	x1,
		const int	x2,
		const int	y
	)			[virtual]

Draws a horizontal line from (x1,y) to (x2,y).

Reimplemented from lti::draw< T >.

template<class T >

void lti::patternDraw< T >::line	(	const int	fx,
		const int	fy,
		const int	tx,
		const int	ty
	)			[virtual]

Draw a line from the point (fx,fy) to point (tx,ty).

The "last point" will be defined with the last "set", "line" or "lineTo" method.

Reimplemented from lti::draw< T >.

template<class T >

void lti::patternDraw< T >::setElement	(	const int	x,
		const int	y
	)			[inline, protected]

Sets a pixel accordings to the current fill or line pattern, depending on the value of filling.

template<class T >

void lti::patternDraw< T >::setFillElement	(	const int	x,
		const int	y
	)			[inline, protected]

Set pixel at x,y in the color set by setColor; also considers the current fill pattern.

Parameters:

	x	x-coordinate of the pixel to be set.
	y	y-coordinate of the pixel to be set.

template<class T >

virtual void lti::patternDraw< T >::setFillPattern

(

const fillPattern &

pat

)

[virtual]

Sets the pattern for filling areas.

All subsequenly filled areas will be filled with the given pattern. The default pattern is a homogenouos fill.

Parameters:

pat

pattern for filling areas.

Reimplemented from lti::drawBase< T >.

template<class T >

void lti::patternDraw< T >::setLineElement	(	const int	x,
		const int	y
	)			[inline, protected]

Set pixel at x,y in the color set by setColor; also considers the current line pattern.

Parameters:

	x	x-coordinate of the pixel to be set.
	y	y-coordinate of the pixel to be set.

template<class T >

virtual void lti::patternDraw< T >::setLinePattern

(

const linePattern &

pat

)

[virtual]

Sets the pattern for drawing lines.

All subsequent lines will be drawn in the given pattern. The default is the continuous line.

Parameters:

pat

pattern for drawing lines.

Reimplemented from lti::drawBase< T >.

template<class T >

void lti::patternDraw< T >::verticalLine	(	const int	x,
		const int	y1,
		const int	y2
	)			[virtual]

Draws a vertical line from (x1,y) to (x2,y).

Reimplemented from lti::draw< T >.
