Picture generation on-the-fly

ruby-talk

Hi All,

is there any library for Ruby, that can generate gif/
jpeg/tiff/png or something other picture format in a
CGI? The picture must contain a password which the
user must type back in a cgi form, like on yahoo and
other sites…

Thanks,

Take a look at gRuby. It’s a Ruby hook for the GD library, so you need that. I
really think that it’ll do what you want:

http://gruby.sourceforge.jp/index.en.html

In particular, take a look at the file “example/font.rb” from the distribution.

There’s also RMagick http://home.nc.rr.com/rmagick/ which can do some
drawing as well (some nice examples here:
http://home.nc.rr.com/rmagick/portfolio3.html ) . It’s based on
ImageMagick.

you brought up an interesting topic: gRuby.

i follow the developtments of
ruby-gd
and
gRuby (which i think is built on top of ruby-gd)
for quite a long time now.

and i can’t see any recent activity (new libversions etc)…

there are so much cool things in newer GD-versions (antialiased line-drawing
for instance) that aren’t supported by the ruby-links to the lib because
they are based on older versions of GD

i wonder whether there are any active developers of these libs out there - i
myself am not that experienced that i could continue developing these :((

i’m just wondering…
