png output failure

[JMcCleery]

Every time I try to generate a png using barby (on ruby 1.9.2, winXP),
the file comes up as an invalid image. I get no errors while
generating it. Is there something I need to change in my setup?

[JMcCleery]

I found that adding the "b" option to the file mode fixed the problem
in windows:
File.open('code128b.png', 'wb')
instead of:
File.open('code128b.png', 'w')

This forces binary mode, and suppresses the conversion to CRLF in
windows.

Hi,

I get same problem when I try to generate a png. The png-file has a size of 1 kb and I get an error message when I try to open the file. This is the code I use.

barcode = Barby::EAN13.new('732351090062')

File.open('barcode.png', 'wb'){|f| f.write barcode }
