I am trying to get a PNG created with GD to output exactly as a
pre-existing PNG file on the server
I have an app that is being very finicky about how it is loading images
:(
Within Quicktime, If I point to the PNG file directly on the server,
it works.
this works:
$image = isset($_GET['image'])? $_GET['image']:"yolanda.png";
$image = "./".$image;
$imageInfo = getimagesize($image);
$mime = $imageInfo['mime'];
header("Content-type:".$mime);
header ("Content-Length:".filesize($image));
header ("Cache-Control:".$cacheInfo);
readfile($image);
If I output a PNG with GD, it does not work within Quicktime for the PC.
My guess is that Quicktime for PC is very finicky when it comes to
headers :(
[excerpt from php script]
$im = imagecreatefrompng($image);
imagettftext($im, $fontSize, 0, 17, 20, $color, $font, $text);
imageAlphaBlending($im, true);
imageSaveAlpha($im, true);
// Output handler
function output_handler($im) {
header('Content-type: image/png');
header('Content-Length: ' . strlen($im));
header('Cache-Control:no-store, no-cache');
return $im;
}
// Image output
ob_start("output_handler");
imagepng($im);
ob_end_flush();
anyone know a bullet proof way to output the headers to look like a
pre-existing PNG file ?
many thanks in advance
