[SOLVED] GD - configuration

ali_2kool2002 · March 31, 2007

does anyone know how to configure GD Library in simple instructions for making bar graphs? please help if you can... im using windows xp with php apache macromedia dreamweaver

Barand · March 31, 2007

1 ) Have you now downloaded the php_gd2.dll file from php.net?

2 ) Have you looked in you php.ini file for the line

extension_dir = xxxx

3 ) Have you put the .dll file in the folder xxxx as defined in the ini file.

4 ) Have you then looked in the php.ini file for the line

;extension=php_gd2.dll

and removed the ; from the beginning.

When you have, let us know.

I know this may sound familiar as I answered this here

i have downloaded the gd2.035rc1 which is one of their latest library, but iv looked inside the folder and cant find a dll file? im using php 5.1.4 if that helps?

thanks for your other reply, is more straight forward

ali_2kool2002 · April 1, 2007

every time i look for a library on php.net it says its moved to another link and when i click the link

it goes to http://www.libgd.org/Main_Page.. this is where i dowloaded the file gd-2.0.35RC1.tar.bz2

which has no dll file.. any further ideas ?thanks

another good site is http://www.maani.us/charts/index.php but the chart doesnt change when i follow its tutorial, is this because it requires GD aswel?

hi iv made some kind of progress as the error of not recognising the image create has gone...

however, i have a error on your script for bar.php its

Notice: Undefined index: val in h:\Project\htdocs\fiinalyear\charts\bar.php on line 23

Notice: Undefined index: max in h:\Project\htdocs\fiinalyear\charts\bar.php on line 24

This version should stop those notices when no values are passed to the script.

<?php
// set dimensions
     $w = 102;
     $h = 12;
// create image
     $im = imagecreate($w, $h);
// set colours to be used
     $bg = imagecolorallocate($im, 0xE0, 0xE0, 0xE0);
     $black = imagecolorallocate($im, 0x00, 0x00, 0x00);
     $barcolor  = imagecolorallocate($im, 0xFF, 0x00, 0x00);
// draw border
     imagerectangle($im, 0,0,$w-1,$h-1,$black);
// get value and max value from query string
     $val = isset($_GET['val']) ? $_GET['val'] : 0;
     $max = isset($_GET['max']) ? $_GET['max'] : 100; 
// calculate dimensions of inner bar
     $barw = $max ? floor(($w-2) * $val / $max) : 0;
     $barh = $h - 2;
// draw inner bar
 if ($barw)
     	imagefilledrectangle($im, 1, 1, $barw, $barh, $barcolor);
// send image header
     header("content-type: image/png");
// send png image
     imagepng($im);
     imagedestroy($im);
?>

ali_2kool2002 · April 1, 2007

the notices have gone but all i get if i go onto bar.php is :

‰PNG IHDRf íÞ Í PLTEàààÿ‡½ß°IDATxœcÅp‘(…; úÙ[Fã\IEND®B`‚

and the other normal html that uses bar.php displays the table but doesnt seem to be able to retrieve the bar.php in the last coumn...

does it work on your system?

ali_2kool2002 · April 1, 2007

if i take the gd2.dll file from the php.net site it says the function is not recognised but if i use the one thats allready on my system the above random txt comes up... i think i need an extension for the png file ?

Barand · April 1, 2007

png support is built in to the gd extension

If you run

<?php

phpinfo();

?>

You will get a list of supported formats.

When I run the sample html I get the attachd image. If I run bar.php on its own with no query string I get a grey rectangle

<?php
echo '<pre>', print_r(gd_info(), true), '</pre>';
?>

Array

(

[GD Version] => bundled (2.0.28 compatible)

[FreeType Support] => 1

[FreeType Linkage] => with freetype

[T1Lib Support] => 1

[GIF Read Support] => 1

[GIF Create Support] => 1

[JPG Support] => 1

[PNG Support] => 1

ITS THE SAME I THINK

Barand · April 1, 2007

bar.php should be

<?php
// set dimensions
     $w = 102;
     $h = 12;
// create image
     $im = imagecreate($w, $h);
// set colours to be used
     $bg = imagecolorallocate($im, 0xE0, 0xE0, 0xE0);
     $black = imagecolorallocate($im, 0x00, 0x00, 0x00);
     $barcolor  = imagecolorallocate($im, 0xFF, 0x00, 0x00);
// draw border
     imagerectangle($im, 0,0,$w-1,$h-1,$black);
// get value and max value from query string
     $val = isset($_GET['val']) ? $_GET['val'] : 0;
     $max = isset($_GET['max']) ? $_GET['max'] : 100; 
// calculate dimensions of inner bar
     $barw = $max ? floor(($w-2) * $val / $max) : 0;
     $barh = $h - 2;
// draw inner bar
 if ($barw)
     	imagefilledrectangle($im, 1, 1, $barw, $barh, $barcolor);
// send image header
     header("content-type: image/png");
// send png image
     imagepng($im);
     imagedestroy($im);
?>

remove all the surrounding html code

AT LAST THE HARD WORK HAS PAID OFF... thanks Barrand....i realy really appreciate your hard work and consisstent help throughout the course of this whole procedure from start to end....great help!! thank you! I fee like sending you a gift ! thanks! :) ;D

ali_2kool2002 · April 1, 2007

Placing a gd produced image with

< img src='an_image.php' >

is the same as placing a static image file (such as jpeg). The only diff is the image is generated on demand from the php code.

If you edited a jpeg file and put the html code at the begining and end then that wouldn't work either.
