# SWFBitmap

(PHP 4 >= 4.0.5)

SWFBitmap -- Loads Bitmap object

## Description

SWFBitmap swfbitmap ( mixed file [, mixed alphafile] )

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

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.

> Note: 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.

Example 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.

Example 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(); ?>`
