How do I save an image created by pChart to a file?

Question

I am using the following:

$chartImage->autoOutput('/statistics/'.$image.'.png');

The problem is that this code outputs the image to the browser. I would prefer it if it saved the image to a file with the directory and name I specified. How do I do this? I was looking at the pChart wiki, and its very confusing with all this pCache stuff. I don't have a need for any caching or anything like that... I just want to save the image.

Try to use:

$chartImage->render("image_name.png");

It worked for me in 1.x, don't know about 2.x - did not used it.

Thanks, that did it... the render function does not appear to be documented in the pChart wiki. – Jason Axelrod Jul 22 '11 at 05:30

Hmm.. Here it is: http://wiki.pchart.net/doc.faq.script.output.html See 'Rendering to a flat file'. – rMX Jul 22 '11 at 05:35

$imageOut = 'grafico';
$chart->drawFromJPG($width, $height, "{$imageOut}.jpg");
$chart->render("{$imageOut}.jpg");

I got this working very well.

If there is no way, then do

ob_start();
$chartImage->autoOutput('/statistics/'.$image.'.png');
$image = ob_get_contents();
ob_end_clean();
$file = fopen('<path_to_file>', 'wb');
fputs($file, $image);
fclose($file);
