Ahh, that's what I was after. Many thanks ;)
However, I can't seem to get PDF::API2's image methods to accept the scalar data as input:
$png = $pdf->image_png($file);
I know my scalar contains a valid PNG image as I've written the source image to a scalar, closed the file handle, opened another and written the scalar back to disc and the file is a valid PNG.
Any ideas on how to do this please?
Thanks again.
