SWFBitmap (PHP 4 >= 4.0.5) SWFBitmap -- Loads Bitmap object DescriptionSWFBitmap swfbitmap ( mixed file [, mixed alphafile] ) 警告 | 本函数是实验性的。本函数的行为,包括函数名称以及其它任何关于本函数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。使用本函数风险自担。 |
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.
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(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(); ?>
