soaked and soaped

As I wrote here I was looking for a way to use QuickLook to produce preview images of files.
On day later Matt Legend Gemmell luckily wrote a little method to do exactly what I wanted.
I took that as a reason to write my first little Objective-C/Cocoa app: A command line tool, which uses QuickLook to generate preview images of files.

It took me some time to get familiar with the ObjC syntax and I noticed it’s really boring to write ObjC apps with a German keyboard layout because of the heavy use of square brackets. My next notebook will definitely have an English keyboard layout!
I also took advantage of the new Garbage Collection in ObjC 2.0 (yeah, you can throw stones on me!). But I think it’s a nice thing for developers who are not so familiar with ObjC/C/C++ like me.

To cut a long story short, here is the code: http://github.com/kommen/quikiee/
Here is the binary: quickiee.zip (requires Mac OS X 10.5, obviously)

Attention: The code is not tested very well and may blow up your computer! :)

How to use?

./quickiee <srcfile> <destfile> <size> <imageformat>

• size: e.g 300×300 means that the maximum width OR height is 300 pixels. The original ratio is kept. If omitted, 200×200 will be used.
• format: can be png, gif, jpg, bmp or tiff. If omitted, png will be used.

Comments, suggestions, enhancements etc. to the code are welcome!
