SWFBitmap

Description

SWFBitmap swfbitmap ( mixed file [, mixed alphafile] )

swfbitmap() creates a new SWFBitmap object from the Jpeg or DBL file in file. alphafile is a MSK file to be used as an alpha mask for a Jpeg image. Both parameters can be fopen() resources or binary strings.

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(file_get_contents("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(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(); ?>
