Привет, ребята, мне нужна помощь.
<form action="sample.php" method="POST" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit" name="submit">
</form>
Затем, когда я нажимаю " Отправить", размер файла изображения будет сведен к минимуму.
Например.
Gaara.JPG = размер файла: 1.50mb;
Но когда я загружаю Размер файла, он будет уменьшаться.
Like = размер файла: 600kb; или меньше.
благодаря
U может попробовать использовать Image Magician script, с помощью которого вы можете обрезать, изменять размер, добавлять водяные знаки, границы и делать другие вещи. Вот ссылка http://phpimagemagician.jarrodoberto.com/
Использование образца:
include_once ('.../php_image_magician.php');
$path = "your/media_media_upload_directory/";
$destination = "your_thumbnails/media_upload/directory/";
if(move_uploaded_file($tmp, $path.$actual_image_name)) {
$magicianObj = new imageLib($path.$actual_image_name);
$magicianObj -> resizeImage(630, 600, 'landscape');
$magicianObj -> addWatermark('your/watermark/folder/watermark.png', 'l', 5);
$magicianObj -> saveImage($path.$actual_image_name, 70);
$magicianObj -> reset();
$magicianObj -> resizeImage(300, 300, 'crop-tl', true);
$magicianObj -> saveImage($destination.$actual_image_name);
}
В этом примере после того, как файл был перемещен из папки tmp в папку с носителями, я изменяю его размер, добавляя водяной знак, а затем пихаю по миниатюре, при действии saveImage у вас есть возможность уменьшить качество от 100 до всего, что вы хотите, на пример качества - 70.
