Here is a simple script using imagefilledellipse to created rounded corners on the fly. It takes
color, bg_color, width, height, and placement (i.e. top left, bottom right) as arguments.
<?php
$color = $_REQUEST['color'];
$bg_color = $_REQUEST['bg_color'];
$c_width = $_REQUEST['width'];
$c_height = $_REQUEST['height'];
$placement = $_REQUEST['placement'];
$width = 2 * $c_width;
$height = 2 * $c_height;
// create a blank image
$image = imagecreatetruecolor($c_width, $c_height);
// fill the corner color
$col_ellipse = hex2int($image, $color);
// fill the background color
$bg = hex2int($image, $bg_color);
// fill the background color
imagefill($image, 0, 0, $bg);
// draw the ellipse
//takes (resource image, int cx, int cy, int w, int h, int color)
// bottom right corner
if ($placement == "br") {imagefilledellipse($image, 0, 0, $width, $height, $col_ellipse);}
// top right corner
if ($placement == "tl") {imagefilledellipse($image, $c_width, $c_height, $width, $height,
$col_ellipse);}
// top left corner
if ($placement == "tr") {imagefilledellipse($image, 0, $c_height, $width, $height,
$col_ellipse);}
// bottom left corner
if ($placement == "bl") {imagefilledellipse($image, $c_width, 0, $width, $height,
$col_ellipse);}
// output the picture
header("Content-type: image/png");
imagepng($image);
function hex2int($image, $color) {
$string = str_replace("#","",$color);
$red = hexdec(substr($string,0,2));
$green = hexdec(substr($string,2,2));
$blue = hexdec(substr($string,4,2));
$color_int = imagecolorallocate($image, $red, $green, $blue);
return($color_int);
}
?>
You would call it like so:
<img src="round_test.php?
width=50&height=50&color=fffefe&bg_color=99e1e0&placement=tr">
