# ImagickDraw::pathLineToRelative

(PECL imagick 2.0.0)

ImagickDraw::pathLineToRelativeDraws a line path

### Beschreibung

bool ImagickDraw::pathLineToRelative ( float `\$x` , float `\$y` )
Warnung

Diese Funktion ist bis jetzt nicht dokumentiert. Es steht nur die Liste der Argumente zur Verfügung.

Draws a line path from the current point to the given coordinate using relative coordinates. The coordinate then becomes the new current point.

### Parameter-Liste

`x`

starting x coordinate

`y`

starting y coordinate

### Rückgabewerte

Es wird kein Wert zurückgegeben.

``` Hope this of help of anything, I had one hell of a time to draw a simple pie slice, where in GD2 is very easily done with the 'arc' function.. this is a bit harder to do in imagick.The degrees are a mess, seems like the path, arc and ellipse functions all use a different system.. utterly confusing.Code below should at least be of help in understanding how it works.For an example of the output, please see: http://www.imagebam.com/image/8e0ca432393602<?php    function getPointOnCircumference( \$widthOfCircle, \$heightOfCircle, \$degrees, \$x = 0, \$y = 0 )    {        return array(             'x' => \$x + (\$widthOfCircle/2)  * sin( deg2rad( \$degrees ) ),            'y' => \$y + (\$heightOfCircle/2) * cos( deg2rad( \$degrees ) )        );    }        \$width  = 200;    \$height = 200;    \$border = 2;    \$x = \$width / 2;    \$y = \$height / 2;    \$im = new Imagick();    \$im->newImage( \$width, \$height, "orange", "png" );            \$draw = new ImagickDraw();    \$draw->setFillColor( 'lime' );    \$draw->setStrokeColor( new ImagickPixel( 'black' ) );    \$draw->setStrokeWidth( 2 );    \$draw->arc( 0, 0, (\$width-\$border), (\$height-\$border), 270, 360  ); //270 till 360 degrees    \$im->DrawImage( \$draw );        \$draw2 = new ImagickDraw();    \$draw2->setFillColor( 'red' );    \$draw2->setStrokeColor( new ImagickPixel( 'black' ) );    \$draw2->setStrokeWidth( 2 );    \$draw2->ellipse( 100, 100, \$x-\$border, \$y-\$border, 0, 90 );         //0 till 90 degrees    \$im->DrawImage( \$draw2 );        \$draw3 = new ImagickDraw();    \$draw3->setFillColor( 'navy' );    \$draw3->setStrokeColor( new ImagickPixel( 'white' ) );    \$draw3->setStrokeWidth( 2 );    \$draw3->pathStart();      \$degrees90  = getPointOnCircumference( \$width-2*\$border,\$height-2*\$border, 360  );      \$degrees180 = getPointOnCircumference( \$width-2*\$border,\$height-2*\$border, 270 );      \$draw3->pathMoveToRelative( \$x, \$y ); //Move 'pencil' to middle of image.      \$draw3->pathLineToRelative(  \$degrees90['x'],  \$degrees90['y'] );      \$draw3->pathEllipticArcRelative( \$width-\$border, \$height-\$border, 0, false, true, \$degrees180['x'], \$degrees180['y']-\$y+\$border );    \$draw3->pathClose();    \$im->DrawImage( \$draw3 );            header( "Content-Type: image/png" );    echo \$im;?> ```
