Hi- does anyone know of a working EXIF library for Ruby that runs on Windows and Linux? So far I’ve tried rexif and ruby-exif without any success. RMagick (RMagick-1.9.2-IM-6.2.4-6-win32) returns some data, but adds a ‘.’ at the end of every value and undfortunately doesn’t seem to handle GPSInfo, which contains most of the info I’m interested in. Thanks for any help, -markus ---

Please try EXIFR, [http://rubyforge.org/projects/exifr](http://rubyforge.org/projects/exifr) gem install exifr It’s a pure ruby EXIF reader so it works on both windows and linux. Please file a bug in the tracker at rubyforge if GPSInfo is not read properly/ at all and send me some examples (including the expected results) since I don’t have any files containing GPSInfo. Thanks, Remco ---

Unfortunately it doesn’t work. I filed a bug report as you suggested. From a quick glance at the code I couldn’t find any support for GPSInfo IFD. But then again I’m very new to ruby, actually this was going to be my first ruby microproject. For the time being I’ve implemented it in python… Thanks, -markus ---

Newbie here. What’s the syntax to read say the date and time the picture was taken? I tried: puts EXIFR::JPEG.new("/file/is/here/tests/data/exif.jpg").date\_time and got: NameError: uninitialized constant EXIFR Maybe I didn’t get it installed right? Thanks for any help. ---

As a follow on to my Newbie question, here’s what I got when I installed it $ sudo gem install exifr Password: Bulk updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org) Successfully installed exifr-0.10.2 Installing ri documentation for exifr-0.10.2… Installing RDoc documentation for exifr-0.10.2… - PS I don’t se an edit for postings.

Specifically MRW (Konica-Minolta)? If how would I get into the OS X hooks for handling this? Maybe this isn’t a Ruby question and I’ll have to go elsewhere. I’m a Newbie to Ruby (groan), but OS X supports many RAW formats. I have Appscript, so assume that’s the path, but was hoping to avoid that for awhile. Thanks for any clues. ---

I have the book and it’s over my head. But Black’s book arrived today. I ordered it because it is supposed to be a good intermediate book. I had looked up all the ARGV refs in Pickaxe and they didn’t make much sense. I get “require,” but still am learning what needs to be “required” and what’s built in. I think I can see how ARGV will be useful, because eventually I’ll be processing all the files in a folder. I’m running from TextMate in OS X, so wasn’t thinking command line (which I use infrequently), so I’ll pull in the file paths some other way. Much to learn and thanks again. Since exifr doesn’t support Raw images (see separate posting), I also have to dig into the hooks to apps in the Mac OS to read the exif for Raw. But now that I’ve got Black I’ll put some time in with that before working on my own project too much. Plus I have to take a vacation to Utah and Colorado in the next two weeks. Poor me. ---

ARGV is a special global Array that holds the other parameters on the command line after the ruby script.

Interfacing ruby with CoreImage, you may want to follow the RubyCocoa project, from their website it says that the unstable branch supports CoreImage (via QuartzCore), [http://rubycocoa.sourceforge.net/doc/unstable/](http://rubycocoa.sourceforge.net/doc/unstable/) I haven’t played with any of these yet, but they do look fun. > Plus I have to take a vacation to Utah and Colorado in the next two > weeks.
