# ImagickDraw::pathLineToRelative

(PECL imagick 2, PECL imagick 3)

ImagickDraw::pathLineToRelativeDraws a line path

### Descrição

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

Esta função não está documentada; apenas a lista de argumentos está disponível.

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

### Parâmetros

`x`

starting x coordinate

`y`

starting y coordinate

`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;?>`
