这个脚本有些如何显示图像的一半而不是整个图像...我想弄清楚这里有什么问题
任何帮助,请
//文件
$ftimage = $_POST['feature_image'];
// maximum height 150 X width 150
$width = 150;
$height = 150;
// Dimensions Set
list($width_orig, $height_orig) = getimagesize($ftimage);
$ratio_orig = $width_orig/$height_orig;
if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}
// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($ftimage);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
// Output
$image = imagejpeg($image_p, null, 100);
var_dump($image);
答案 0 :(得分:-1)
尝试替换它
$ftimage = $_POST['feature_image'];
用它:
$ftimage = $_POST['feature_image']['tmp_name'];
或者,如果在您的POST请求中存储了远程图像的URL,请尝试以下操作:
$image = imagecreatefromstring(file_get_contents($ftimage));
