PDF417 Bar Code Width/Height

Hello,

First, if this has been addressed already, I apologize; I couldn't find any other threads discussing PDF417 bar codes aside from release notes.

I'm trying to use a PDF417 bar code and it is being generated too tall. Looking at the spec, PDF417 allows for 3 to 90 rows in the bar code. The Reports.Wpf product seems locked at 3 rows (columns?) so it gets taller instead of wider. Is it possible to increase the number of rows generated so that we could generate a wider, yet shorter code?

Thanks,
Adam

Hello,

By default the automatic selection of the barcode size according to the value of the AspectRatio property (the ratio of the barcode width and height) is set.
The AutoDataColumns and AutoDataRows properties defines the direction in which the selection of the size will be carried out automatically.
In your case please set the AutoDataRows property to false, and select the desired value of the DataRows property. Now when you change the amount of data only the width of the barcode will be changed.

Also, we have found a bug in Designer.Wpf, because of which all the properties of the barcode were not shown.
The problem will be solved in the coming days. The patch will be available in the next prerelease build.

Thank you.

Wonderful, that sounds like exactly what we need. I didn't think to look at the properties programmatically; I was only looking at the designer, so I think I must just have run into that bug. I'll check it out whenever the prerelease comes out. Thanks!
