PHP & GD

Howdy folks:

Here is my perdiciment. I have a map for a game I play. In the game, you can use a Sextant to find your x,y cords. I'm trying to make a program that when given the x and y cords will place a star or circle where the cords meet. For ease treat the map as starting at each corner of the map with no border, I can fix that by changing the x,y cords. But I can't seem to find any resources on how to just put an image at a specific cordinate without using a huge program that creates Scatter graphs.

Map: http://mononexo.com/map/map.jpg

Any tips? Snippets?

Thanks,

Matt

Hi. Perhaps try something like the following:
PHP Code:
<?php
  $pic 
"filename.jpg"// jpg filename
  
$font 5// can be 1, 2, 3, 4, or 5
  
$xpos 50// zero is leftmost position
  
$ypos 10// zero to topmost position
  
$qual 30// zero (worst) to 100 (best)
  
$symb "*"// symbol to denote x,y point
  
$im imagecreatefromjpeg($pic);
  
$red imagecolorallocate($im,255,0,0);
  
imagestring($im$font$xpos$ypos$symb$red);
  
imagejpeg($im''$qual);
  
imagedestroy($im);
?>
Also, check here for other image functions.
