Coming to the party late. I'm finding it useful to generate png qr codes that are larger than the smallest possible, and having good luck using the xdim attribute:

barcode = Barby::QrCode.new("http://github.com/")
File.open('barcode3.png', 'w'){|f| f.write barcode.to_png(xdim: 5) }

from barby.

How do you know it ignores them? And where did you find out about them?

I am using Barby 0.5.1 with chunky_png 1.2.8.

require 'RMagick'

def draw_barcode2(id, options = {})

barcodes_dir = FileUtils.mkdir_p("/Users/kasper/projects/barcoda/barcodes")

barcode = Barby::Code128B.new(id)

File.open(File.join(filepath), 'w') do |f|

f.write barcode.to_image(:margin => 0,

:height => options[:height],

:width => options[:width])

end
end
I tehn run it as:

puts draw_barcode2('1-4-019', :width => 70, :height => 260, :rotate => true)
puts draw_barcode2('1-4-019', :width => 70, :height => 260, :rotate => false)
puts draw_barcode2 '1-4-021', :width => 280, :height => 70

puts draw_barcode2('1-4-020', :width => 70, :height => 260, :rotate => true)
puts draw_barcode2('1-4-020', :width => 70, :height => 260, :rotate => false)
puts draw_barcode2 '1-4-021', :width => 280, :height => 70

Retina:

puts draw_barcode2 '1-4-022', :width => 560, :height => 120

I'm seeing this issue too.

barcode.to_png(height: 100, width: 600, margin: 5)

Gives me an image with a width of 364px.

Having the same problem here. Generates 100px qrcodes, no matter the options informed

from barby.

There is no width option.

from barby.

I'm not using width option

require 'barby'
require 'barby/barcode/qr_code'
require 'barby/outputter/png_outputter'

barcode = Barby::QrCode.new("http://github.com/")
File.open('barcode3.png', 'w'){|f| f.write barcode.to_png(height: 300, margin: 5) }

The options are completely ignored

from barby.

You need to be more specific. What results are you expecting and what are you seeing?

from barby.

I expect a 300px height png, and I'm getting a 100px height png

Regards,

Sandro

Ok; the height option isn't valid for 2D barcodes, for the same reason that
width isn't available for any barcode: It's not possible to impose those
dimensions on the result without corrupting it.

as a response to cluesque's comment, going smaller is not possible, xdim: 1, is the default and as small as you can go using the png_outputter

from barby.
