Barcodes
-
I have an application which generates a report. This report is then converted to PDF and sent out into the world. Recently a barcode was added to add to the reports functionality but the PDF creator totally stuffs this up and the barcode comes out looking very different from the original one, and the scanner also doesn't pick it up. How can I ensure that the barcode wont change when the document is printed/converted to PDF?

It's probably rendered as a bitmap and the PDF creator converts it to an embedded JPEG with very poor resolution and quality (high compression). If you can get it to convert graphics to a lossless format, e.g. PNG, and keep the resolution at 300dpi, it will probably work a lot better, but your file will be significantly larger. If you can get the original barcode rendered as a metafile instead of as a bitmap, and your convertor can convert that metafile into PDF-compatible vector graphics, that would probably be even better. (working with barcodes since 2001)

What PDF creator application are you using? I use the Amyuni driver and create barcodes using the DLSoft barcode toolkit with no problems. I have also used Win2PDF and PDF995 with no issues like this...

I have just finished a barcode related software development for the company I work for. While we don't utilise PDF's (and I do understand it's the conversion into PDF that is the issue) I found that simply using a barcode font provided the consistency I needed rather than trying to generate images all over the place. The font I have used is Abri Barcode39[[^](http://Abri Barcode39)] but I can't see why your PDF converter wouldn't convert this as accurately as Verdana or Arial... :~

The Amyuni driver is by far the best. You have full control over the quality of JPEG images, embedded fonts, etc. Very easy to use. Not free though... but you can distribute it with your apps once you have a copy (I *think* it costs about $500). http://www.amyuni.com[^]

Change the Adobe settings to "Scan as Image"
