The perfect solution would be a SVG object inside an XHTML document, but I don't know what is the current status of SVG support.
Else PHP has support for generating images, and I seem to remember there's a pseudo-protocol named 'data:' for embedding the graphics inside the markup.

Sure...

PHP Code:



<?php echo '<hr />'; ?>

That's so true! But only for horizontal lines, though.

Huhl?
I'm sorry but either I missunderstand your question or you have absolutely zero knowledge about web, html and php.
How are the two points specified and what kind of "line" do you have to "draw"?
I suggest you read at least the first chapter of any book on web and html.

PHP Code:



<?php 
header("Content-type: image/png"); 
 
$im = @imagecreate(100, 100) 
   or die("Cannot Initialize new GD image stream"); 
$background_color = imagecolorallocate($im,  
                                255, 255, 255 //white 
                                ); 
 
$black = imagecolorallocate($im, 0, 0, 0); 
imageline($im, 
        5, 5, // first point coordinates 
        80,80, // last point coordinates 
        $black); 
 
imagepng($im); 
imagedestroy($im); 
?>

(requires that php is compiled with gd)
