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.
