.NET print multiple pdf's on a page (like check images on a bank statement)

Hi.
We have customer signature "tickets" scanned as PDF's.  
We want to combine images of the tickets on a single page, like you would see your bank check images on a bank statement.   (Do banks still do that?)   For example, we might have 25 tickets per customer, and we would print 6 images per page and mail that to them with their invoice.

I don't know if a report tool like ActiveReports or CrystalReports will do this, or if some sort of .Net library like iTextPDF   would be the only answer ( ... not that I have any experience with iTextPDF).

Anyone have any suggestions?
Thanks!

Hi Rob,
I recommend making a command line call to GraphicsMagick from your .NET code. Here are two EE articles that discuss the basic technique:

Create a PDF file with Contact Sheets (montage of thumbnails) for all JPG files in a folder and each of its subfolders using an automated, batch method

Create an image (BMP, GIF, JPG, PNG, TIF, etc.) from a multi-page PDF

Neither of those is exactly what you want. but it's simply a matter of sending the right parameters to GM in the command line call. In your case, since you want six images per page, and since checks are landscape (width bigger than height), I recommend a -tile parameter of 2x3 (i.e., two columns and three rows). Since you're already scanning as PDFs, the input files will all be PDF and, of course, the output file will be PDF. I think that should do it for you. Regards, Joe

You're welcome. Please post back here when you get a moment to let me know how it goes for you. Btw, you may want to use the -geometry parameter to specify the size of each check in the montage PDF (what my article calls the ThumbnailPixelSize variable). Good luck on the project! Regards, Joe
