Line thickness/metafiles

rec · Post by **rec** » Mon Apr 14 2008

We are using v3.0.1.1 and have a problem with line thickness when drawing metafiles. We have a 3rd party barcode toolkit, that generates a metafile which is then drawn on the DC using PlayMetaFile. We have been using this toolkit for a long time with no problems. However, when generating a PDF, the barcode lines are too thick, which means the barcodes will not scan correctly. Are there any know problems with drawing metafiles or line thicknesses in general? Any help would be appreciated. We once used a rival product (Win2PDF) which used to have an issue with the thickness of lines, and wondered if Amyuni is suffering from a similar issue.

I have done more tests and there is definitely a problem with line thickness using the Amyuni driver. I generated a PDF that contains boxes drawn with line thickness's of various point sizes, and thin lines (less than 1pt) all look the same. Similarly, a 1.5pt line looks the same as a 2pt. This would explain why barcodes do not render correctly, as the thickness of each bar needs to be spot-on. Perhaps the driver is rounding up the line width or something?

We had an issue in the line thickness in very old version of the PDF Conveter that was solved way behind, before version 2 even.

Which viewer are you using to view the generated pdf files? Adobe Reader or our PDF Creator? I suggest that you adjust the zoom factor of the viewer, this will change how the line thickness appears.

If this didn't help, I suggest that you open a case with technical support and send us the original file you are trying to print to check it and try to produce this issue. You can send your sample to support@amyuni.com
