Hi,
I'm used the code below from Seanf (running with GD). It gave me thumbnail OK with full colors; but if I change $max_width = 120; and $max_height = 100 (since I want larger thumbnail), most colors in the image will be lost. What's to do?
Thanks,
John
PHP Code:<?php
$image = 'coverr.jpg';
if (!$max_width)
$max_width = 80;
if (!$max_height)
$max_height = 60;
$size = GetImageSize($image);
$width = $size[0];
$height = $size[1];
$x_ratio = $max_width / $width;
$y_ratio = $max_height / $height;
if ( ($width <= $max_width) && ($height <= $max_height) ) {
$tn_width = $width;
$tn_height = $height;
}
else if (($x_ratio * $height) < $max_height) {
$tn_height = ceil($x_ratio * $height);
$tn_width = $max_width;
}
else {
$tn_width = ceil($y_ratio * $width);
$tn_height = $max_height;
}
$src = ImageCreateFromJpeg($image);
$dst = ImageCreate($tn_width,$tn_height);
ImageCopyResized($dst, $src, 0, 0, 0, 0,
$tn_width,$tn_height,$width,$height);
header("Content-type: image/jpeg");
ImageJpeg($dst, null, -1);
ImageDestroy($src);
ImageDestroy($dst);
?>
