Write An Image Created By A Charting Class To A Bitmap File

Hi

I have a barchart created by the chartdirector program available as a stream of bits that I then print using the print php statement, viz.:

print($c->makeChart2(PNG));

With the makechartChart2 being the operation of the barcharting class.

I do not have the GD graphics library loaded but need to find some way to save the stream of bits as a file so that I can later make it available to a class (part of the fpdf library) that can insert the image as a picture in a pdf document.

Does anybody have a solution.?

Help would be appreciated.
Thanks

If you print the content, why not just saving the content to a variable like this:
$pic = $c->makeChart2(PNG);

// output bits
print $pic;

//write pic to file:
$fp = fopen('/name/of/pic.png', 'w+');
fputs($fp, $pic);
fclose($fp);
