GD Installation problem

Tony Clarke

Hi,

I'm haveing some problems I'm trying to generate bar charts dynamically by
pulling data from an MS Access databasae using an ODBC connection and then
generating the bar charts, this is all on WinXP Pro by the way. I have no
problems with getting the data out of the database and sorting it. I was
using this tutorial
http://www.phpbuilder.com/columns/wi...r20001218.php3 as a guidline to
generating the images, but nothing seems to be working for me.
My problem is that I cannot generate any images using any of the
GD image functions. I have loaded the php_gd2.dll in the php.ini file and I
can see that the dll is loaded when I do a phpinfo(); the probelm is that
none of the pages are generating any images.
I would be greatful if somebody would be able to assist.

Thanks,

Tony

Example code? What errors do you get? What happens when you try to view the
images? Have you sent the right content-type header? Are there PHP error
messages being produced (this corrupts the image)?

I dont get any errors, doing a phpinfo(); shows GD installed. I use a html
with an <img> tag to call the php file that is supposed to generate the
image. Example code below is saved in a file called chart.php and use the
img src tag to call it. On the html page I just get a space as if the html
page could not find the image. Any help would be greatly appreciated.

<HTML>
<BODY>
<H1>RMAs Raised</H1>
<IMG SRC="test1.php" HEIGHT="250" WIDTH="480">
</BODY>
</HTML>
<?php
//-------------------- chart.php file
header ("Content-type: image/png");
$img_handle = ImageCreate (230, 20) or die ("Cannot Create image");
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10);
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191);
ImageString ($img_handle, 31, 5, 5, "My first Program with GD",
$txt_color);
ImagePng ($img_handle);
?>

Sorry, that image tag below should be
<IMG SRC="chart.php" HEIGHT="250" WIDTH="480">

Try commenting out the header() line, make sure error reporting is on and see
what's up. That should give you a human-readable error. I'm asssuming you have
your paths right (your 2 files have to be in the same directory)...

These are two separate files, right?
Also the <img> references test1.php whereas the comment says this is
chart.php.
header ("Content-type: image/png");
If image creation is going wrong, it can be useful to comment out the
content-type header line so you get it dumped out as text - that way you'll see
any error messages.
$img_handle = ImageCreate (230, 20) or die ("Cannot Create image");
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10);
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191);
ImageString ($img_handle, 31, 5, 5, "My first Program with GD",
$txt_color);
ImagePng ($img_handle);
?>
