Method: Easyzpl::LabelTemplate#variable_bar_code_pdf417

Defined in:
lib/easyzpl/label_template.rb

#variable_bar_code_pdf417(x, y, params = {}) ⇒ Object

This creates a PDF417 bar code, which is very common in the automotive industry. The format is as follows: ^B7o,h,s,c,r,t o = Orientation

N - normal, R rotated 90 degrees clockwise, I inverted 180 degrees
B - Read from bottom up 270 degrees

h = height for individual rows in dots
