 Thumbnail |
 |
Hello,
I would like to make thumbnails with gd1 or 2.
I have the code to do this but i don't know how to implement this in images.mdu
Can someone help?
Code:
<?php
function make_thumb ($img_src, $img_th)
{
// some configuration, please match to your server settings
$gd_version = 2;
$thumb_on = 'x';
$thumb_size = 100;
$quality = 30;
$img_size = GetImageSize ($img_src);
$img_in = ImageCreateFromJPEG ($img_src);
if ($thumb_on == 'y')
{
$img_x = ($thumb_size/$img_size[1]) * $img_size[0];
$img_y = $thumb_size;
}
else
{
$img_y = ($thumb_size/$img_size[0]) * $img_size[1];
$img_x = $thumb_size;
}
if ($gd_version == '1')
{
$img_out = ImageCreate($img_x, $img_y);
ImageCopyResized ($img_out, $img_in, 0, 0, 0, 0, $img_x, $img_y, $img_size[0], $img_size[1]);
}
elseif ($gd_version == '2')
{
$img_out = ImageCreateTrueColor($img_x, $img_y);
ImageCopyResampled ($img_out, $img_in, 0, 0, 0, 0, $img_x, $img_y, $img_size[0], $img_size[1]);
}
ImageJPEG ($img_out, $img_th, $quality);
ImageDestroy ($img_out);
ImageDestroy ($img_in);
}
if (isset ($_FILES['image']['name']))
{
$fn = $_FILES['image']['name'];
$src = 'images/'.$fn;
$th = 'thumbs/'.$fn;
if (!@move_uploaded_file ($_FILES['image']['tmp_name'], $src)) die ('Can not upload file...');
make_thumb ($src, $th);
echo "Done!<BR>Original Image:<img src=\"$src\"><BR>Thumbnail Image:<img src=\"$th\">";
}
?>
<form name="form" id="form" action="$PHP_SELF?mod=images" method="post" enctype="multipart/form-data">Thumbnail this file: <input name="image" type="file"><input type="submit" value="Send File"></form>
Regards,
Chris

Why don't you use the built-in thumbnail function?

Because the standard function does not make that nice thumbnails.
The qauality is not so good as with GD 2.

Open images.mdu and change imagecopyresize to imagecopyresampled.
That's it. And you are right, the quality is better. 
(I will change this in the download file as well.)
