I'm new to PDF417, and I'm having a problem. I am kind of in a testing phase, and wrote a quick VB application that takes an input string then encodes it for PDF417 using the ActiveX control that was sent with the fontset. I then take the encoded string and plug it into a fillable PDF and drop it into a text field utilizing the PDF417 font. For some reason, the resultant barcode looks very odd. Basically, it takes each line of the bar code and puts at least two carriage returns between them so the bar code is not stacked directly on top of each other into one barcode, but look live several individual barcodes double spaced in a long column. I skipped the middle step and had the VB application create the barcode directly and was met with similar results, except this time it doesn't have any carriage returns, it just strings them all out end to end. Any thoughts?

Loopy,
First make sure that you resize the text box to hold a full PDF417 row. If the text box is too small, the line will wrap and extra spaces will be displayed.
If you still see extra blank line between the rows, the text box may not handle the line feed propertly. By default, the encode ActiveX outputs "\r\n" (corresponding to vbCrLf) at the end of each line. Some text box interpreates these two characters as two carriage returns. If that is the case, set LineFeedString property to chr(13), or "\n" only.
object.LineFeedString = chr(13)

How do you make the PDF file? We tested with distiller and no problems. Some third party PDF programs may not handle \r\n properly.

Well, first I was just copying the encoded text from the VB app and pasting it into the PDF file. Now, I'm outputting the encoded text to a file and reading it in through a data object in Acrobat. I'm running Acrobat 7 professional.

The thing is, it's a fillable PDF, and I enter the data directly into a text field on the PDF, not distilling it.

Now I understand. It seems that the internal height of the font needs some modification to accommodate this scenario. I will get back to you once we have a solution.

I'm still getting the same result. Is there any way I could send you my PDF so you can test it there and see if I'm just screwing up something over on this end?

Loopy,
Send the PDF to support@morovia.com we'll take a look.
Also you may consider starting with a new PDF document after you install the new fonts. Acrobat grabs the fonts into the document right after you create an edit box and select the font.

You know what, I didn't think about that. I'll try a new PDF and see what happens.

The fonts worked on Acrobat 6.0. After I moved the document to 7.0, the barcode initially looked good, but extra spaces appear whenever I change the content.
I'll think about it and get back to you soon.
