警告

本扩展模块是实验性的。该模块的行为,包括其函数的名称以及其它任何关于此模块的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。我们提醒您在使用本扩展模块的同时自担风险。

swfbitmap() creates a new SWFBitmap object from the Jpeg or DBL file named filename. alphafilename indicates a MSK file to be used as an alpha mask for a Jpeg image.

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

SWFBitmap has the following methods : swfbitmap->getwidth() and swfbitmap->getheight().

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.

例子 1. Import PNG files

<?php
  $s
= new SWFShape();
  
$f = $s->addFill(new SWFBitmap("png.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();
?>

And you can put an alpha mask on a jpeg fill.

例子 2. swfbitmap() example

<?php

  $s
= new SWFShape();

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