changing absolute position pointer location

TimTimTimma

Hello, its been awhile, I am currently working on a GD script that uses x and y coordinates to display a little message saying "<--You are here" on a map. Now traditionally it seems the pointed is located always to the left side of any text I add to it, which is fine, EXCEPT when i get close to the right edge of the map! I need it to switch from "<--you are here" to "you are here-->", this is simple enough, but the pointer is still located on the left side of "you are here-->", is there anyway I can relocate this pointer from the left side to the right side sometimes?

probably is. But we do not know your script.

<?php 

$base_url = "http://phpublisher.net";

switch($_GET['map']){
	case 1;
		$map = $base_url."/test/sec1.jpg";
	break;

	case 2:
		$map = $base_url."/test/sec2.jpg";
	break;

	case 3:
		$map = $base_url."/test/sec3.jpg";
	break;

	case 4:
		$map = $base_url."/test/sec4.jpg";
	break;

	default:
		$map = "http://phpublisher.net/test/sec1.jpg";
	break;
}

$image = ImageCreateFromJPEG($map);
$text_color = ImageColorAllocate($image, 000, 000, 000);	
Header("Content-type: image/jpeg");
ImageString ($image, 5, $_GET['xpos'], $_GET['ypos'], $_GET['code'], $text_color);
ImageJPEG($image, '', 75);
ImageDestroy($image);
?>

Its very simple..i need need to know how to change the position of the pointer frm left to right

Just had a look in the manual , and I think you'll have to write a function which calculates the length, and moves the x/y coordiantes

For you, I hope I am wrong 😃
