TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
I recommend you do set a "dpi" in SnagIT. That gives you, at least, a
standard for all your images. Maybe you can then resize only a few
exceptions, rather than each and every capture. And, remember, while a
screen capture is only about a number of pixels, resolution information
is used by desktop publishing software to determine relative image
dimensions on the page.
The JPEG versus PNG versus GIF versus TIFF versus EPS debate is all
about file-type limitations. Pick the type that meets your needs. None
is absolutely "better" than the others, with a nod to JPEG's lossy
compression being a potential drawback.
As for blurryness on-screen, it can be addressed successfully, if you
want, though the place to do it is not in FrameMaker unless you are
delivering FrameMaker files to your reader; the place to consider this
is in the PDF output, if that is your deliverable.
