Changing imagefilledrectangle to an actual image.

[roofrauf]

I am using this script (which is from http://www.web-max.ca/PHP/)

function getlocationcoords($lat, $lon, $width, $height)
{
   $x = (($lon + 155.4) * ($width / 360));
   $y = ((($lat * -1) + 123) * ($height / 180));
   return array("x"=>round($x),"y"=>round($y));
}

// These are the coordinates the location we wish to plot.
// These are being passed in the URL, but we will set them to a default if nothing is passed.

if(empty($long))$long = [i]longgoeshere [/i];
if(empty($lat)) $lat = [i]latgoeshere[/i];

// First we load the background/base map. We assume it's located in same dir as the script.
// This can be any format but we are using JPG in this example
// We will also allocate the color for the marker

$im = imagecreatefrompng("[i]imagegoeshere[/i]");
$red = imagecolorallocate ($im, 255,0,0);

// Next need to find the base image size.
// We need these variables to be able scale the long/lat coordinates.

$scale_x = imagesx($im);
$scale_y = imagesy($im);

// Now we convert the long/lat coordinates into screen coordinates

$pt = getlocationcoords($lat, $long, $scale_x, $scale_y);

// Now mark the point on the map using a red 4 pixel rectangle

imagefilledrectangle($im,$pt["x"]-.1,$pt["y"]-.1,$pt["x"]+.1,$pt["y"]+.1,$red);

// Return the map image. We are using a PNG format as it gives better final image quality than a JPG

header ("Content-type: image/png");
imagepng($im);
imagedestroy($im);

 

imagefilledrectangle($im,$pt["x"]-.1,$pt["y"]-.1,$pt["x"]+.1,$pt["y"]+.1,$red)

 

^^ This is the line that I want to change...I want to replace the rectangle with an actual image that will still plot at the coordinates calculated earlier in the script.

Thanks
