I am having difficulty with pdf417, if anybody can tell me what is
happening, I would appriciate it.

Here is a working example:
415 331 moveto (M000005392|RFS-042942|Q260|UEA|L501313910|F|A501313910|
D20090805|) (columns=13 eclevel=8) pdf417

Here is the example generating errors:
415 331 moveto (M000005392|RFS-042942|Q260|UEA|L501313810|F|A501313810|
D20090805|) (columns=13 eclevel=8) pdf417

can anybody tell me how to resolve this?

Lance

Hi Lance,

At first glance it looks as though you've found an input that triggers
a bug in the Reed-Solomon error correction code which is emitting a
value of 929, when it should output values in the range 0-928.

I'll attempt to debug this soon.

Thanks,

Tez
