I love the idea of using PHP to insert data into Postscript. I'm just not sure how to make it happen.
The good news is that I've got barcodes drawing just the way I need them: http://www.winecarepro.com/kiosk/fast/shell/barcodemerge.ps The bad news is that's all hard-coded Postscript. I'd like to take your suggestion and use PHP to loop-through and draw the barcodes - - - however, if I put anything that resembles PHP in my .ps file, bad things happen. Anyone know the secret to creating a postscript .ps file that had PHP code injecting data into it? Here's the source file that works. Where PHP would be handy is at the very bottom of the script.... http://www.winecarepro.com/kiosk/fast/shell/barcodemerge.ps.zip On Mar 23, 2010, at 7:48 AM, Richard Quadling wrote: > On 23 March 2010 05:48, Jochem Maas <joc...@iamjochem.com> wrote: >> Op 3/23/10 3:27 AM, Rob Gould schreef: >>> I am trying to replicate the functionality that I see on this site: >>> >>> http://blog.maniac.nl/webbased-pdf-lto-barcode-generator/ >>> >>> Notice after you hit SUBMIT QUERY, you get a PDF file with a page of >>> barcodes.
