My workflow for flawless screenshots
Here is my workflow that gives flawless screenshots - although its a bit of work:
1. open a clean white background (e.g. textedit)
2. get your app in front that you want to screenshot
3. SHIFT-COMMAND-4 and find out the X, Y coordinates as well as hight and width of the window you want to screenshot (they are depicted in your cursor) - remember them
4. open a terminal window and make a screenshot with the following command line:
screencapture -T 10 -P -R551,325,1095,647 screenshot.png
- -T 10 means you have 10 seconds time to "prepare" your app (open a menu etc)
- -R means the region that should be captured the coordinates <x,y,w,h> are the ones you found out before
- -P means that it will open in preview so you can check the output
Save this one as PNG.

How to look at the real PDF source behind the 'raw' binary parts
Jay Birkenbilt's qpdf is a very useful commandline tool (available for Linux, Mac OSX and as source code, under the open source Artistic License), which can unpack most filtered content and re-organize the internal structure in a way that gives you much more insight into it (all objects are numerically ordered, etc.). The commandline to achieve this is:
qpdf --qdf original.pdf unpacked.pdf
Another useful and free tool (GPL licensed, but Linux-only AFAIK) to look into PDFs is of coursePDFEdit. This one even comes with a GUI (if you prefer that), while still allowing you access to the internal structure and "raw" PDF code.
