Creates the new SWFBitmap object from the given
file
.
Parameter Liste
For both parameters you can provide a file pointer returned by
fopen() or the image data, as a binary string.
file
Anmerkung:
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.
Beispiele
Beispiel 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(); ?>

Beispiel 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(); ?>
