This example describes how to generate a rounded corner image using php. Share it with you for your reference. The details are as follows:
The code is as follows: <? Php
$ 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, 100, $ size [0], $ size [1 );
$ 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,), hexdec (substr ($ backcolor,), hexdec (substr ($ backcolor, 4, 2 )));
$ Fg = imagecolorallocate ($ im_temp, hexdec (substr ($ forecolor,), hexdec (substr ($ forecolor,), 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, $ size [0], $ size [1], $ startx, $ starty );
// Output final image
Header ("Content-type: image/png ");
Imagepng ($ image );
