SWFBitmap::__construct

(PHP 5 <= 5.3.0, PECL ming SVN)

SWFBitmap::__construct — Loads Bitmap object

说明

SWFBitmap::__construct ( mixed $file [, mixed $alphafile ] )

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。

Creates the new SWFBitmap object from the given file.

参数

For both parameters you can provide a file pointer returned by fopen() or the image data, as a binary string.

file

Note:

We can only deal with baseline (frame 0) jpegs, no baseline optimized or progressive scan jpegs!

You can't import png images directly, though- have to use the png2dbl utility to make a dbl ("define bits lossless") file from the png. The reason for this is that I don't want a dependency on the png library in ming- autoconf should solve this, but that's not set up yet.

alphafile

An MSK file to be used as an alpha mask for a JPEG image.

范例

Example #1 Importing a DBL file

  <?php
$s  = new  SWFShape ();
 $f  =  $s -> addFill (new  SWFBitmap ( file_get_contents ( "image.dbl" )));
 $s -> setRightFill ( $f );

 $s -> drawLine ( 32 ,  0 );
 $s -> drawLine ( 0 ,  32 );
 $s -> drawLine (- 32 ,  0 );
 $s -> drawLine ( 0 , - 32 );

 $m  = new  SWFMovie ();
 $m -> setDimension ( 32 ,  32 );
 $m -> add ( $s );

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

Example #2 Using an alpha mask

  <?php

$s  = new  SWFShape ();

 // .msk file generated with "gif2mask" utility
 $f  =  $s -> addFill (new  SWFBitmap ( file_get_contents ( "alphafill.jpg" ),  file_get_contents ( "alphafill.msk" )));
 $s -> setRightFill ( $f );

 $s -> drawLine ( 640 ,  0 );
 $s -> drawLine ( 0 ,  480 );
 $s -> drawLine (- 640 ,  0 );
 $s -> drawLine ( 0 , - 480 );

 $c  = new  SWFShape ();
 $c -> setRightFill ( $c -> addFill ( 0x99 ,  0x99 ,  0x99 ));
 $c -> drawLine ( 40 ,  0 );
 $c -> drawLine ( 0 ,  40 );
 $c -> drawLine (- 40 ,  0 );
 $c -> drawLine ( 0 , - 40 );

 $m  = new  SWFMovie ();
 $m -> setDimension ( 640 ,  480 );
 $m -> setBackground ( 0xcc ,  0xcc ,  0xcc );

 // draw checkerboard background
 for ( $y = 0 ;  $y < 480 ;  $y += 40 ) {
  for ( $x = 0 ;  $x < 640 ;  $x += 80 ) {
     $i  =  $m -> add ( $c );
     $i -> moveTo ( $x ,  $y );
  }

   $y += 40 ;

  for ( $x = 40 ;  $x < 640 ;  $x += 80 ) {
     $i  =  $m -> add ( $c );
     $i -> moveTo ( $x ,  $y );
  }
}

 $m -> add ( $s );

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