# SWFBitmap->__construct()

(no version information, might be only in CVS)

SWFBitmap->__construct() -- Loads Bitmap object

## Descrição

class SWFBitmap {
SWFBitmap __construct ( mixed file [, mixed alphafile] )
}

Atenção
Esta função é EXPERIMENTAL. Isso quer dizer que o comportamento desta função e seu nome, incluindo TUDO o que está documentado aqui pode mudar em futuras versões do PHP, SEM QUALQUER NOTIFICAÇÃO. Esteja avisado, e use esta função por sua própria conta e risco.

Creates the new SWFBitmap object from the given `file`.

## Parâmetros

For both parameters you can provide a file pointer returned by fopen() or the image data, as a binary string.

`file`

  > Nota: 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.

## Exemplos

Exemplo 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(); ?>`

Exemplo 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(); ?>`
