hi all,

i wanna generate thumbnail from image

i found RMagick and found this code but i can’t run it, so please anyone help me in this issue.

my code

def index img = Magick::Image.read (‘/images/img2.jpg’).first width, height = 100, 100 thumb = img.resize(width, height) thumb.write(‘/images/mythumbnail.jpg’) end

but it throws this exception

unable to open image `/images/img2.jpg': No such file or directory

thanks

Image.read() is relative not to your web root, but to your host operating system's root.

Try something like:

def index   fname = RAILS_ROOT + '/images/img2.jpg'   img = Magick::Image.read(fname)   img = img.first   ... end
