Превью картинок
- <?php
- function resize ($filename, $size)
- {
- $pref = 'mini_';
- $img = strtolower(strrchr(basename($filename), "."));
- $imgname = basename($filename);
- $formats = array('.jpg', '.gif', '.png', '.bmp');
- if (in_array($img, $formats))
- {
- list($width, $height) = getimagesize($filename);
- $new_height = $height * $size;
- $new_width = $new_height / $width;
- $thumb = imagecreatetruecolor($size, $new_width);
- switch ($img)
- {
- case '.jpg': $source = @imagecreatefromjpeg($filename); break;
- //создаем превьюшки
- case '.gif': $source = @imagecreatefromgif($filename); break;
- case '.png': $source = @imagecreatefrompng($filename); break;
- case '.bmp': $source = @imagecreatefromwbmp($filename); break;
- }
- imagecopyresized($thumb, $source, 0, 0, 0, 0, $size, $new_width, $width, $height);
- switch ($img)
- {
- case '.jpg': imagejpeg($thumb, $pref.$imgname); break;
- case '.gif': imagegif($thumb, $pref.$imgname); break;
- case '.png': imagepng($thumb, $pref.$imgname); break;
- case '.bmp': imagewbmp($thumb, $pref.$imgname); break;
- }
- }
- else return 'Error';
- @imagedestroy($thumb);
- @imagedestroy($source);
- return $imgname;
- }
- ?>
Вот пример использования
echo '<img src="mini_'.resize('http://www.moysait.rf/test.jpg',200).'" />';
echo '<img src="mini_'.resize('http://www.moysait.rf/test.jpg',200).'" />';
