How to change PDF417 Module Width?

[Rajendar]

Hi,

 

As per requirement I want to change the generating pdf417 barcode module width is 28.5 mils.I searched within zxing code but couldn't get any idea where to change to within zxing pdf417Encoder part to generate the barcode with the mentioned module width?

 

Another query is even I changed the Aspect Ratio = 3 within PDF417Writer.java file , barcode is being generated with 352 Widh and 96 Height size, not exactly like 300W:100H.To generate the barcode I have given following inputs to get 3:1 aspect ratio

 

MinRows = MaxRows = 6

MinCols = MaxCols = 12

Width = 300

Height = 100

Compaction Mode = "Text"

 

Please give me some idea where to change the code to get changed module width?

I found the constant within PDF417.java If I change this one will get reflect?
