SWFShape::setLine

(PHP 5 <= 5.3.0, PECL ming SVN)

SWFShape::setLine — Sets the shape's line style

说明

void SWFShape::setLine ( SWFShape $shape )

void setLine ( int $width , int $red , int $green , int $blue [, int $a ] )

Warning

此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担。

swfshape::setline() sets the shape's line style. width is the line's width. If width is 0, the line's style is removed (then, all other arguments are ignored). If width > 0, then line's color is set to red, green, blue. Last parameter a is optional.

You must declare all line styles before you use them (see example).

返回值

没有返回值。

范例

This simple example will draw a big "!#%*@", in funny colors and gracious style.

Example #1 swfshape::setline() example

  <?php
$s  = new  SWFShape ();
 $f1  =  $s -> addFill ( 0xff ,  0 ,  0 );
 $f2  =  $s -> addFill ( 0xff ,  0x7f ,  0 );
 $f3  =  $s -> addFill ( 0xff ,  0xff ,  0 );
 $f4  =  $s -> addFill ( 0 ,  0xff ,  0 );
 $f5  =  $s -> addFill ( 0 ,  0 ,  0xff );

 // bug: have to declare all line styles before you use them
 $s -> setLine ( 40 ,  0x7f ,  0 ,  0 );
 $s -> setLine ( 40 ,  0x7f ,  0x3f ,  0 );
 $s -> setLine ( 40 ,  0x7f ,  0x7f ,  0 );
 $s -> setLine ( 40 ,  0 ,  0x7f ,  0 );
 $s -> setLine ( 40 ,  0 ,  0 ,  0x7f );

 $f  = new  SWFFont ( 'Techno.fdb' );

 $s -> setRightFill ( $f1 );
 $s -> setLine ( 40 ,  0x7f ,  0 ,  0 );
 $s -> drawGlyph ( $f ,  '!' );
 $s -> movePen ( $f -> getWidth ( '!' ),  0 );

 $s -> setRightFill ( $f2 );
 $s -> setLine ( 40 ,  0x7f ,  0x3f ,  0 );
 $s -> drawGlyph ( $f ,  '#' );
 $s -> movePen ( $f -> getWidth ( '#' ),  0 );

 $s -> setRightFill ( $f3 );
 $s -> setLine ( 40 ,  0x7f ,  0x7f ,  0 );
 $s -> drawGlyph ( $f ,  '%' );
 $s -> movePen ( $f -> getWidth ( '%' ),  0 );

 $s -> setRightFill ( $f4 );
 $s -> setLine ( 40 ,  0 ,  0x7f ,  0 );
 $s -> drawGlyph ( $f ,  '*' );
 $s -> movePen ( $f -> getWidth ( '*' ),  0 );

 $s -> setRightFill ( $f5 );
 $s -> setLine ( 40 ,  0 ,  0 ,  0x7f );
 $s -> drawGlyph ( $f ,  '@' );

 $m  = new  SWFMovie ();
 $m -> setDimension ( 3000 , 2000 );
 $m -> setRate ( 12.0 );
 $i  =  $m -> add ( $s );
 $i -> moveTo ( 1500 - $f -> getWidth ( "!#%*@" )/ 2 ,  1000 + $f -> getAscent ()/ 2 );

 header ( 'Content-type: application/x-shockwave-flash' );
 $m -> output ();
 ?>

Just wanted to point out that a $width value of 0 does _not_ prevent the line from being drawn. It causes a non-scaling, single pixel line to be drawn. This is analogous to the way this is handled in ActionScript (see http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/Graphics.html#lineStyle%28%29)

If you do not want a line to be drawn at all, use NAN for $width instead of zero.
