Phatch – Simple Image Editing and Batch Processor

Friday, July 2nd, 2010

So, I’m still going through all of the Libre Graphics Meeting videos and today I watched a short tutorial on Phatch, a batch image processor.  Basically, it’s a graphical ease of use layer on top of many command line tools such as ImageMagick or the scripting languages of other open source graphics applications such as Gimp, Inkscape or Blender.  It’s also a batch processor making it a snap to edit many files all at once.

It serves as an image “recipe box” rather than an editor.  Therefore it allows you to save how you edit one image so that later you can come back to that recipe and rerun the edits simply, whether after a lunch break or a year later for another project.  It also shows the power of mashing open source applications together to get huge productivity gains with a minimum of effort.

Phatch makes it easy to do effects you see all across the web such as reflections, rounded corners and perspective changes.  It also allows you to mix and match them in any order.  This has got to be a huge time saver for website image content managers.  I’m sure I’ll be using it in the future as I start to develop the look and feel of this blog.

It’s probably also helpful for those of you that aren’t very tech savvy.  Phatch can function as a quick way to do more complex effects without having to figure out all of the intricacies of a more powerful image editor like Gimp or Photoshop.

Since it was already in the Ubuntu software repositories (the repositories are basically an “app store” for open source software where everything is free), I had it installed in seconds.  I tried it out and it worked just like the video showed.  Looks like Windows and OSX are supported, but still don’t have a standard installer.  Help them out if you get a chance to get the installers tested out so that it is easier to use for your non-techy friends!  Here’s a great opportunity to contribute.

Really the only downside I saw was that their website was obnoxiously littered with Google ads which made it hard to figure out what was content and what wasn’t.

Hope it comes in handy!  Let me know how it goes!

Finding Books to Get Started In Open Source

Tuesday, June 8th, 2010

Getting started into any new software can be a daunting experience whether open source or not.  For open source projects, you want to find mature projects that generally “just work” and shouldn’t give you many problems.  How do you know if an open source project is mature?

One of the quickest ways is to see if any books have been published for the project.  If a book has been written, that generally means that the product has a large user base that the publisher can sell into.  More users means more bugs found and fixed and therefore more stability.  It also means more feature requests and more developers to work on the requests which means a more robust and useful product.  Usually by the time there is a book out, an open source project has good documentation.  However, many times documentation can be too dry and technical for the average user.  Books are meant to be more readable and useful for those not willing to wade through the specifics of every feature.  Many times books are organized around concepts and projects rather than grouped by feature like documentation usually is which makes them more useful to average users as well.

Even better, because open source projects are invested in open source culture, sometimes the books are released under liberal Creative Commons licenses in digital form so that you can download and easily check out the book to see if it fits you before you invest in buying it if you choose to.  Again, open source culture isn’t just about software; it includes many things like books.  Here is an example of just such a book about Getting Started in Open Office.

Most books are available from Amazon or other online book sellers where you can buy them used or new.  So, as my mom says, let your fingers do the walking and see what’s available for a project you’re interested in.  If you don’t find a book, that doesn’t mean the project isn’t mature and useful (we’ll keep looking at more ways to decide maturity in future posts).  On the other hand, if you do find books available, then chances are really good that the project is mature enough for almost anyone to use.  Here’s a few links to books for several of the most used open source projects.

Open Office – an office suite similar to Micro$oft Office

Inkscape - a vector graphics editor similar to Adobe Illustrator

Gimp – a raster graphics editor similar to Adobe Photoshop

Scribus – a desktop publishing application similar to Adobe InDesign

Firefox – the best web browser (at least for now) ;)

Ubuntu – a user friendly and robust operating system similar to Mac OSX or Microsoft Windows

Various Open Source Media Software – covers installing Ubuntu, audio recording and editing, animation, video editing, font creation, graphic design tools, and much more

If you have other recommendations for good books for learning an open source software package, please post them in the comments.

RealWorks Walkthrough – Professional Media With Open Source

Monday, June 7th, 2010

If you don’t think that open source can put out professional video and animated media, you should check out this virtual design tour done for RealWorks.  Everything was done in Blender except for some texturing in Gimp.   If you don’t know, Blender is a really great multimedia software package that does animation, but so much more.  It includes a lot of the functionality you’d find in After Effects, Maya, ZBrush, Premiere, Cinema 4D, etc.

Kdenlive Quick Start

Monday, April 12th, 2010

Today is the day I deliver on my promise to post tutorials for the first time.  This weekend I did a quick recording about Kdenlive to match a similar post about Final Cut Pro on the ChurchCreate blog.  It is basically just a Kdenlive Quick Start to help you, um, get started quickly using Kdenlive.

If you are not farmiliar with Kdenlive, it is a non-linear video editing application similar to Final Cut Pro, Vegas, Premiere, etc.  It currently is supported on Linux and Mac only, however, using VirtualBox you can run it on Windoze.  Kdenlive even has VirtualBox images already set up and created for you to use.

Why use Kdenlive?  Besides the prohibitive cost of most commerical non-linear video editors, Kdenlive is not only free, but also very full featured, has a great workflow, and is fairly stable. In fact, you’ll see the Kdenlive’s setup is actually pretty similar to FCP in it’s layout.   Some of the more advanced features are still being incorporated or are a little clunky to use.  On the other hand, Kdenlive will be able to handle most any standard editing task you can throw at it.

I will go ahead and apologize ahead of time for meandering a little too much and not being a little more focused.  I’m sure I’ll improve the quality of the video tutorials as I do more of them.  I hope it is helpful all the same.

Also, if you’re interested in other video tutorials.  Kdenlive has several video tutorials on their site already.

Enjoy the introduction to Kdenlive.
