Hi there,

I’m trying to send binary data (e.g. gif file) to a web browser using
the following code:

f = File.open(gif_filename, “rb”)
content = f.read(filesize)
f.close

print “Content-type: image/gif\n\n”
print content

I’m using ruby for windows. I’m getting problems because every 0x0a
will be converted to 0x0d 0x0a. Must I use another method to print
binary data for output? I’ve found nothing in the ruby documentation.

Hi Ara,

sorry, that’s not the problem. I’ve used f.binmode as well as
f.read(filename, “rb”) where b is for binary.

But thanks for your help.

Cheers,
