Tumbnail Script
Auteur: Stijn1 Dennisvb
Dit is een klein scriptje, waarmee je een dir kan laten uitlezen en dat hij automatisch al de images Tumbnailed naar de juiste grootte (de grootte door jouw gekozen)
Vb om de class te gebruiken:
<?php
$dir = new tumb_dir('path/naar/de/dir', 'voorvoegsel_', array('toegelate', 'extenties'), 'Maximale grootte van de lanste zijde', 'recursief of niet (submappen zoeken) in true of false');
// dus hier vb met ingevulde waardes:
$dir = new tumb_dir('/home/scripts4/public_html/stijn/', 'tumb_', array('jpg', 'gif', 'png'), '100', true);
?>
<?php
$dir = new tumb_dir
( 'path/naar/de/dir' , 'voorvoegsel_' , array ( 'toegelate' , 'extenties' ) , 'Maximale grootte van de lanste zijde' , 'recursief of niet (submappen zoeken) in true of false' ) ; // dus hier vb met ingevulde waardes:
$dir = new tumb_dir
( '/home/scripts4/public_html/stijn/' , 'tumb_' , array ( 'jpg' , 'gif' , 'png' ) , '100' , true ) ; ?>
Als je een foto hebt, met de hoogte bijvoorbeeld 1000 en de breedte 500, als je dan maximale hoogte 100 zet krijg je de hoogte: 100 en de breedte 50
Hij blijft dus in dezelfde verhouding... (vanonder heb ik een vb dat je de dir kan ingeven...)
Code:
