My impression is that Raul wasn't seriously considering adding that statement (for the Hough tranform task anyway). The task doesn't require you to show how to download the file from the internet so the following is all that is really needed. require 'media/platimg' MyRGBmatrix=: readimg 'Pentagon.png'
That doesn't mean that it wouldn't be nice to be able to read the file directly from the internet to an array. This isn't possible on Windows right now because of what may be a bug in wget. Using curl rather than wget works fine. > From: Alex Rufon > Sent: Wednesday, 11 August 2010 17:46 > > I've been lurking ... > > I just want to say that I'm a bit apprehensive about adding "install > cygwin's wget and imagemagick" as part of the instruction.
