Yes and no. A lot depends on the image format, the software you're working
with, the output format... If the original post had asked, "How do I retain
text readability when resizing screen captures?" I'd be asking about those
three things. There are ways to approach that issue without going into
vector graphics.
Generic advice to anybody resizing bitmaps:
* If you're resizing in Paint, don't; it does a terrible job. Photoshop
does pretty well if you're in RGB mode (not indexed color, which has a
limited color palette; anti-aliasing goes out the window), and presumably
other image editors like PSP would be similar. If you resize in Photoshop
in RGB mode, the resulting screen capture will be a little blurry but
readable.
* If the bitmap image is getting distorted in a PDF file, check the
Distiller settings (search the archives).
* But better yet, don't resize. Crop the screen capture instead and show
just the relevant portion at 100%. That way you get perfect clarity and the
added bonus that you can direct your reader's attention right to whatever
it is you're discussing at the moment. IMO, full-screen captures aren't
useful for much besides "This is what the Widget Details screen looks
like."
