How to generate rounded images in php,

The example in this article describes how to generate rounded images in php. Share it with everyone for your reference. The details are as follows:
Copy code The code is as follows: $image_file = $_GET['src'];
$corner_radius = isset($_GET['radius']) ? $_GET['radius'] : 20; // The default corner radius is set to 20px
$topleft = (isset($_GET['topleft']) and $_GET['topleft'] == "no") ? false : true; // Top-left rounded corner is shown by default
$bottomleft = (isset($_GET['bottomleft']) and $_GET['bottomleft'] == "no") ? false : true; // Bottom-left rounded corner is shown by default
$bottomright = (isset($_GET['bottomright']) and $_GET['bottomright'] == "no") ? false : true; // Bottom-right rounded corner is shown by default
$topright = (isset($_GET['topright']) and $_GET['topright'] == "no") ? false : true; // Top-right rounded corner is shown by default
$imagetype=strtolower($_GET['imagetype']);
$backcolor=$_GET['backcolor'];
$endsize=$corner_radius;
$startsize=$endsize*3-1;
$arcsize=$startsize*2 1;
if (($imagetype=='jpeg') or ($imagetype=='jpg')) {
$image = imagecreatefromjpeg($image_file);
} else {
if (($imagetype=='GIF') or ($imagetype=='gif')) {
$image = imagecreatefromgif($image_file);
} else {
$image = imagecreatefrompng($image_file);
}
}
$size = getimagesize($image_file);
// Top-left corner
$background = imagecreatetruecolor($size[0],$size[1]);
imagecopymerge($background,$image,0,0,0,0,$size[0],$size[1],100);
$startx=$size[0]*2-1;
$starty=$size[1]*2-1;
$im_temp = imagecreatetruecolor($startx,$starty);
imagecopyresampled($im_temp, $background, 0, 0, 0, 0, $startx, $starty, $size[0], $size[1]);
$bg = imagecolorallocate($im_temp, hexdec(substr($backcolor,0,2)),hexdec(substr($backcolor,2,2)),hexdec(substr($backcolor,4,2)));
$fg = imagecolorallocate($im_temp, hexdec(substr($forecolor,0,2)),hexdec(substr($forecolor,2,2)),hexdec(substr($forecolor,4,2)));
if ($topleft == true) {
imagearc($im_temp, $startsize, $startsize, $arcsize, $arcsize, 180,270,$bg);
imagefilltoborder($im_temp,0,0,$bg,$bg);
}
// Bottom-left corner
if ($bottomleft == true) {
imagearc($im_temp,$startsize,$starty-$startsize,$arcsize,$arcsize,90,180,$bg);
imagefilltoborder($im_temp,0,$starty,$bg,$bg);
}
// Bottom-right corner
if ($bottomright == true) {
imagearc($im_temp, $startx-$startsize, $starty-$startsize,$arcsize, $arcsize, 0,90,$bg);
imagefilltoborder($im_temp,$startx,$starty,$bg,$bg);
}
// Top-right corner
if ($topright == true) {
imagearc($im_temp, $startx-$startsize, $startsize,$arcsize, $arcsize, 270,360,$bg);
imagefilltoborder($im_temp,$startx,0,$bg,$bg);
}
$newimage = imagecreatetruecolor($size[0],$size[1]);
imagecopyresampled($image,$im_temp,0,0,0,0,$size[0],$size[1],$startx,$starty);
// Output final image
header("Content-type: image/png");
imagepng($image);
imagedestroy($image);
imagedestroy($background);
imagedestroy($im_temp);
?>
