Google Maps Dynamic Marker Icons - dynamic

Question

I am well aware that google offers as part of their chart api dynamic marker icons for google maps here:
https://developers.google.com/chart/image/docs/gallery/dynamic_icons
There is just only one small problem, the whole API seems to be deprecated. Plus I would really like to have more variety because not all of the icons offer the same flexibility.
So I found this webpage:
http://mapicons.nicolasmollet.com/numbers-letters/numbers/?style=classic
The icons look nice but they are not dynamic and well my client doesn't seem to like em. So is there a differenct webpage or some other sort of service which offers neat dynamic icons?
Doesn't have to be for google maps. Can be for any purpose just be suitable for maps as well :-)
Thank you in advance!

Answer 1

OK, I did a project some time ago that does exactly this but its independent of google maps, even though I used it to create dynamic map markers. Here is the whole php function:
<?php
function createImage($number, $color) {
$blank = "/var/www/rbc/dashboard/images/".$color."-0.png";
//$image = #imagecreatefrompng($blank);
$image = LoadPNG($blank);
// pick color for the text
$fontcolor = imagecolorallocate($image, 255, 255, 255);
$font = 2;
$fontsize = 8;
$width = imagefontwidth($font) * strlen($number) ;
$height = imagefontheight($font) ;
$x = (imagesx($image) - $width) / 2;
$y = 5;
//white background
$backgroundColor = imagecolorallocate ($image, 255, 255, 255);
//white text
$textColor = imagecolorallocate($image, 255, 255, 255);
// preserves the transparency
imagesavealpha($image, true);
imagealphablending($image, false);
imagestring($image, $font, $x, $y, $number, $textColor);
// tell the browser that the content is an image
header('Content-type: image/png');
// output image to the browser
imagepng($image);
// delete the image resource
imagedestroy($image);
}
function LoadPNG($imgname) {
/* Attempt to open */
$im = imagecreatefrompng($imgname);
/* See if it failed */
if(!$im) {
/* Create a blank image */
$im = imagecreatetruecolor(150, 30);
$bgc = imagecolorallocate($im, 255, 255, 255);
$tc = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 150, 30, $bgc);
/* Output an error message */
imagestring($im, 1, 5, 5, 'Error loading ' . $imgname, $tc);
}
return $im;
}
if(!isset($_GET['color'])) {
$_GET['color'] = "blue";
}
if(!isset($_GET['number'])) {
$_GET['number'] = "99";
}
createImage($_GET['number'], $_GET['color']);
?>
which you show with <img src="image.php?color=red&number=2" />
