ImagickDraw::pathStart — Declares the start of a path drawing list
本函数还未编写文档,仅有参数列表。
Declares the start of a path drawing list which is terminated by a matching DrawPathFinish() command. All other DrawPath commands must be enclosed between a and a DrawPathFinish() command. This is because path drawing commands are subordinate commands and they do not function by themselves.
没有返回值。
Example #1 ImagickDraw::pathStart()
<?php
function pathStart ( $strokeColor , $fillColor , $backgroundColor ) {
$draw = new \ ImagickDraw ();
$draw -> setStrokeOpacity ( 1 );
$draw -> setStrokeColor ( $strokeColor );
$draw -> setFillColor ( $fillColor );
$draw -> setStrokeWidth ( 2 );
$draw -> setFontSize ( 72 );
$draw -> pathStart ();
$draw -> pathMoveToAbsolute ( 50 , 50 );
$draw -> pathLineToAbsolute ( 100 , 50 );
$draw -> pathLineToRelative ( 0 , 50 );
$draw -> pathLineToHorizontalRelative (- 50 );
$draw -> pathFinish ();
$draw -> pathStart ();
$draw -> pathMoveToAbsolute ( 50 , 50 );
$draw -> pathMoveToRelative ( 300 , 0 );
$draw -> pathLineToRelative ( 50 , 0 );
$draw -> pathLineToVerticalRelative ( 50 );
$draw -> pathLineToHorizontalAbsolute ( 350 );
$draw -> pathclose ();
$draw -> pathFinish ();
$draw -> pathStart ();
$draw -> pathMoveToAbsolute ( 50 , 300 );
$draw -> pathCurveToAbsolute ( 50 , 300 , 100 , 200 , 300 , 300 );
$draw -> pathLineToVerticalAbsolute ( 350 );
$draw -> pathFinish ();
$imagick = new \ Imagick ();
$imagick -> newImage ( 500 , 500 , $backgroundColor );
$imagick -> setImageFormat ( "png" );
$imagick -> drawImage ( $draw );
