# Shiege Iseng Resize Class
# 11 March 2005
# shiegegeATyahoo.com
# http://shiege.com/scripts/thumbnail/
/*############################################
Sample :
$thumb=new thumbnail("./shiegege.jpg"); // generate image_file, set filename to resize/resample
$thumb->size_width(100); // set width for thumbnail, or
$thumb->size_height(300); // set height for thumbnail, or
$thumb->size_auto(200); // set the biggest width or height for thumbnail
$thumb->jpeg_quality(75); // [OPTIONAL] set quality for jpeg only (0 - 100) (worst - best), default = 75
$thumb->show(); // show your thumbnail
$thumb->save("./huhu.jpg"); // save your thumbnail to file
----------------------------------------------
Note :
- GD must Enabled
- Autodetect file extension (.jpg/jpeg, .png, .gif, .wbmp)
but some server can't generate .gif / .wbmp file types
- If your GD not support 'ImageCreateTrueColor' function,
change one line from 'ImageCreateTrueColor' to 'ImageCreate'
(the position in 'show' and 'save' function)
- If your GD not support 'ImageCopyResampled' function,
change 'ImageCopyResampled' to 'ImageCopyResize'

ustteki kodu resize.php olarak kayıt edin.
kullanımı
<?
include("resize.php"); //include class
$thumb=new thumbnail("./shiegege.jpg"); // generate shiegege.jpg
if ($_GET["size"]<50 || $_GET["size"]>500) { // 50-500 pixels will resize
echo "resize range 50 pixels - 500 pixels"; exit();
}
if ($_GET["mode"]=="height") { // mode resize
$thumb->size_height($_GET["size"]);
} elseif ($_GET["mode"]=="width") {
$thumb->size_width($_GET["size"]);
} elseif ($_GET["mode"]=="auto" || empty($_GET["mode"])) {
$thumb->size_auto($_GET["size"]);
}
$thumb->show(); // show resize
if ($_GET["save"]==1) // if save selected
$thumb->save("./shiegege_thumb.jpg");
?> [/PHP]
Bende bu şekilde kullanıyorum.
<?
include("resize.txt");
$thumb=new thumbnail("./resim1.JPG");// Küçülecek resim
$thumb->size_width(94); // genişliği 94px yapar eğer aşağıdaki kod varsa bunu dikkate almaz
$thumb->size_height(56); // yüksekliği 56px yapar eğer aşağıdaki kod varsa bunu dikkate almaz
$thumb->size_auto(200); // genişliğini 200 yapıp orantılı olarak boyunuda kısaltır
$thumb->jpeg_quality(75);// Resim kalitesi 75 önerilir 1 ile 100 arasında rakam girilir orjinalliğe göre
$thumb->show();// göster demek :) Küçük resmi
$thumb->save("./resim1_kucuk.jpg"); //küçülen resmin adı
?>
