Another tip... I wanted to centre the barcode in the PDF, and then advance my cursor afterwards. So by looking at the code I saw how the width is calculated...
x_scale = 2
y_scale = 10
margin = 0
barcode = PDF417.new("my data to encode")
data = StringIO.new(barcode.to_png(margin: margin, x_scale: x_scale, y_scale: y_scale))
barcode_width = barcode.bit_columns * x_scale + margin * 2
image = pdf.image(data, at: [(pdf.bounds.width - barcode_width) / 2, pdf.cursor])
pdf.move_down(image.height)
from pdf417.
On my case I just did this on prawn document:
barcode = StringIO.new(PDF417.new("my data to encode").to_png)
image barcode, width: 200, height: 35
Because i don't need special coordinates.
