Windows Presentation Foundation (WPF) and XAML

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've not seen WPF in action... I read a little of the documentation. I think my previous post answers your question, but I'll restate it: WPF will not improve on your ability to resize bitmaps.

    Terrence,

    What was the quality of WPF when viewing images that were portrait quality? Vector is great for graphics, but falls short for things such as photography. Does WPF address this?

    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.

    Hi Trudie,
    I don't have any problem with making screenshots bigger - and ending up blurry. Maybe we can address that issue instead? I'm not too much into playing the letters game futures, but if you really want to, I'll slink away and be quiet. On the other hand, if you want to tackle your "blurry" problem, here I am . . . giggle . No, really!
