Gradient fills are implemented in SWF as a color ramp, mapped onto a square from (-16384, -16384) to (16384, 16384) TWIPS.
The following code creates a movie, displaying a square with a gradient fill, correctly scaled to the size of the shape.
<?php
ming_setscale(1.0);
$m = new SWFMovie();
$m->setRate(12.0);
$m->setDimension(400,400);
$m->setBackground(0xff, 0xff, 0xff);
$sx = 300;
$sy = 300;
$s = new SWFShape();
$g = new SWFGradient();
$g->addEntry(0.0, 0x00, 0x00, 0xff); $g->addEntry(1.0, 0xff, 0xff, 0x00); $f = $s->addFill($g);
$f->moveTo($sx/2, $sy/2);
$f->scaleTo($sx/32768, 1);
$s->setRightFill($f);
$s->drawLine($sx, 0);
$s->drawLine(0, $sy);
$s->drawLine(-$sx, 0);
$s->drawLine(0, -$sy);
$sh = $m->add($s);
$sh->moveTo(50, 50);
header("Content-type: application/x-shockwave-flash");
$m->output();
?>
