I'm resizing images so no matter what size (dims not file size) people
up load, the image will always fit on the screen where I want it to.
I tried the following script (from PHP.net) and it works great...
<?php
// File and new size
$filename = "12.jpg";
// Set a maximum height and width
$width = 200;
$height = 200;
// Content type
header('Content-type: image/jpeg');
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);
$ratio_orig = $width_orig/$height_orig;
if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}
// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height,
$width_orig, $height_orig);
// Output
imagejpeg($image_p, null, 100);
?>
What I need to do is display the output image in say a cell in a table
but I can't get it to work.
For example...
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">
</head>
<body>
<table width="120" border="0" cellspacing="0">
<tr>
<td><?php imagejpeg($image_p, null, 100);?> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
But this just outputs what looks like the text version of the image.
Anyone got any idea??
Many Thanks
Mike
