You don't need an extension for that. You've already got
Ruby-GTK and RMagick. Just glue them together with Ruby.
He's probably wondering specifically how to get from an RMagick
image to a GdkPixbuf or similar (a question I don't know the answer
to offhand), in pure Ruby.

If this helps, I work with unixODBC + Ruby ODBC + Informix on Solaris
all the time without problems. I wrote an Informix adapter for Rails
this way that works fine
Talking about extensions, I'll attempt to write the native Informix
extension for Ruby. It would be nice to see if someone else find it
useful.

There *is* an ODBC for *nix. No clue on it's reliability.

Its very easy:
my_pixbuf = Gdk::Pixbuf.new(rmagic_image.to_blob,
Gdk::Pixbuf::ColorSpace::RGB, false, 8, image_width, image_height,
image.width * 3)
the API reference for the gdk-pixbuf call is:
Gdk::Pixbuf.new(data, colorspace, has_alpha, bit_per_sample, width,
height, rowstride)
rmagic_image.to_blob returns the pixel data

Hello, I'm trying to load an 8x8 GIF file and embed it directly into some HTML but the image pixels are out of order and the dimensions are not correct. I assume the problem is with the byte order during the read. Can any of you suggest a better way to do this?

require 'base64'
gif_path = 'C:\work\gifTest\gifTest.gif'
html_path = 'C:\work\gifTest\gifTest.html'
f = File.open( gif_path, "rb" )
data = f.read
f.close
encoded = Base64.encode64( data )
f = File.open( html_path, 'w' )
# links work perfectly
f.puts( "<IMG SRC=file:///C:/work/gifTest/gifTest.gif>" )
f.puts( "<IMG SRC=file:///#{gif_path}>" )
# something appears, but out-of-order and wrong dimension
f.puts( "<IMG SRC=\"javascript:'#{data}'\">" )
# these produce the "missing image" placeholder
f.puts( "<IMG SRC=\"data:image/gif;base64,#{data}\">" )
f.puts( "<IMG SRC=data:image/gif;base64,#{data}>" )
f.puts( "<IMG SRC=javascript:'#{data}'>" )
f.close
