func.php文件,当图像上传到网站时,它生成缩略图。我明白如何通过5半径圆润的边角,但由于某种原因,我很为难,现在在哪里纳入圆角到我的代码,请大家帮忙:如何使用php和html在缩略图上创建圆角?
<?php
function create_thumb($directory, $image, $destination) {
$image_file = $image;
$image = $directory.$image;
if (file_exists($image)) {
$source_size = getimagesize($image);
if ($source_size !== false) {
$thumb_width = 100;
$thumb_height = 100;
switch($source_size['mime']) {
case 'image/jpeg':
$source = imagecreatefromjpeg($image);
break;
case 'image/png':
$source = imagecreatefrompng($image);
break;
case 'image/gif':
$source = imagecreatefromgif($image);
break;
}
$source_aspect = round(($source_size[0]/$source_size[1]), 1);
$thumb_aspect = round(($thumb_width/$thumb_height), 1);
if ($source_aspect < $thumb_aspect) {
$new_size = array($thumb_width, ($thumb_width/$source_size[0]) * $source_size[1]);
$source_pos = array(0, ($new_size[1] - $thumb_height)/2);
} else if ($source_aspect > $thumb_aspect) {
$new_size = array(($thumb_width/$source_size[1]) * $source_size[0], $thumb_height);
$source_pos = array(($new_size[0] - $thumb_width)/2, 0);
} else {
$new_size = array($thumb_width, $thumb_height);
$source_pos = array(0, 0);
}
if ($new_size[0] < 1) $new_size[0] = 1;
if ($new_size[1] < 1) $new_size[1] = 1;
$thumb = imagecreatetruecolor($thumb_width, $thumb_height);
imagecopyresampled($thumb, $source, 0, 0, $source_pos[0], $source_pos[1], $new_size[0], $new_size[1], $source_size[0], $source_size[1]);
switch($source_size['mime']) {
case 'image/jpeg':
imagejpeg($thumb, $destination.$image_file);
break;
case 'image/png':
imagepng($thumb, $destination.$image_file);
break;
case 'image/gif':
imagegif($thumb, $destination.$image_file);
break;
}
}
}
}
?>
你不能只是使用CSS的'边界radius'?如果你使用http://css3pie.com/它甚至可以在IE6上工作:) – biziclop 2012-08-14 20:01:27
是的CSS是更好更优雅的解决方案。你为什么不使用它? – bksi 2012-08-14 20:02:29
