saving a GD library generated image

[gerkintrigg]

Hi all.

 

I've found a great script to generate pie charts as images, but now I want to save the image to import into something else. I can do it fine from the browser, but want to save it automatically via the script.

 

In the script, I reference to it like this:

<img src="includes/pie_charts/print.php?data=15*35*25*25&label=eggs*carrots*Milk*Bread" />

An include file does the rest for me...

Do I need to hack the source or can I write a function to handle it from the reference?

 

Thanks.

in print.php your see a line like this

imagejpeg($im);

add this line above it (note you may need to change $im to whatever the variable name is

if(!empty($_GET['file'])) imagejpeg($im, dirname(__FILE__)."/tmp/".basename($_GET['file']).".jpeg");

Now in the pie_charts folder create a folder called tmp and give it write privileges.

 

now this

<img src="includes/pie_charts/print.php?data=15*35*25*25&label=eggs*carrots*Milk*Bread&file=test" />

will display the image as normal but will also create test.jpg in the tmp folder,

 

without seeing the code that about the best i can think of.

in the print.php i now have this:

function OutputImage($img) 
{
header('Content-type: image/jpg');
if(!empty($_GET['file'])) imagejpeg($img, dirname(__FILE__)."/tmp/".basename($_GET['file']).".jpeg");
ImageJPEG($img,NULL,100);
}

 

and in the file that references to it:

<img src="includes/pie_charts/print.php?data=1*2*3*94&label=a*b*c*d&file=test" />

 

It displays fine... I'm not sure whether the image is being created though. how will I know?

Look in the tmp folder you created
