Printing barcode with bars of 1.5pixels width

Mathias_Hansen

Hello.
Im trying to make a specific barcode system using a custom-made C# program with Navision.
The problem is, that I need the thin bars to have a with of 1.5pixels???

My solution is to make the bars 3.0pixels and scale the barcode 50% on printing.

Now the question is...
Can I scale the printing from navision?...
Or is there a way I can write a C# program temporarily setting the printer to do this?

Can you use fontsize?

... Do you mean set the fontsize in navision? Yes...

So it sounds like you're creating a barcode bitmap dynamically and printing it? .NET has a SetResolution(x_dpi, y_dpi) method for the Bitmap class. Did you try it? Set the resolution to 300 x 300, and the total pixel size to x_inches*300 x y_inches*300.

Impressive!

image.SetResolution(###, ###);
This does the trick!

I already tried this, but failed because my mind was too set on the 1.5Pixels-problem.
The width in pixels doesn't change, but the actual width when printing is.

Thank you sooo much.

I need to enlarge the barcode image so I wonder where I can change the resolution of target created barcode image. :roll:
