Windows Presentation Foundation (WPF) and XAML

Question

Hi,
I just saw a high-level presentation about Windows
Presentation Foundation (WPF) and XAML. I understand that one of
the advantages to using this new desktop technology is better
control over image resolution. I'm no techie, but I immediately
thought of the challenges we Captivate users have of trying to make
screenshots larger, but having them end up blurry. Will this new
technology somehow help with this problem? Thanks!

I wouldn't think so.
AFAIK, WPF is the XML language that windows will use to
render the interfaces. Without knowing too much about it I imagine
that it will build parts/all of the Vista interface with vectors as
opposed to bitmaps which will work better for a greater number of
montiors (e.g. check out the windows XP boot splash bitmap on a
large hi res montior....ewww!). However, this will not make a
difference to resizing a captured image of the interface.
For the purposes of this discussion let's say vectors are
mathematical descriptions of what should be drawn (shape, outline,
fill, gradient, etc) while bitmaps are images with a fixed number
individually coloured of pixels/dots.
Screenshots images are generally captured in a bitmap format.
When you attempt to increase the overall dimensions of the image
your image processing software makes a guess as to what color each
pixel/dot must be in the resized image based on a sample from the
original image and that's why they tend to look blurry. The better
your software can guess/resample, then the better the resulting
image.
