GD Percentage Bar

Recommended Posts

Hi folks,

I'm using this code to make a GD percentage bar ~ but the bar starts at the top and goes down the page.
Can anyone help me to adapt it so it starts at the bottom and goes up.

(does that make any sense?)

Thanks,
S.C>

(bar.php?per=70)

[code]<?php
    // returns a PNG graph from the $_GET['per'] variable
    $per = imagecreate(32,302);
    $background = imagecolorallocate($per, 0xFF, 0xFF, 0xFF);
    $foreground = imagecolorallocate($per, 0x00, 0x8A, 0x01);
    $border = imagecolorallocate($per, 0x99, 0x99, 0x99);
    if ($_GET['per'] > 0)
    {
        $grad = imagecreatefrompng("grad.png");
//        $per2 = imagecopy($per, $grad, 1, 1, 0, 0, 30,($_GET['per'] * 3));
        $per2 = imagecopy($per, $grad, 1, 1, 0, 0, 30,($_GET['per'] * 3));         
        imagerectangle($per, 0, 0, 31, 301, $border);         
    }
    header("Content-type: image/png");
    imagepng($per, '', 100);
?> [/code]

You have to flip your calculations. Instead of working out x% is complete, you must work out y% is incomplete.

PNG's render from top to bottom, so that is your restriction.
