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.
The reason you get a "too many colors" error when saving as GIF is that GIF
only supports 256 colors (just as BMP only supports RGB, etc.). If your
desktop is set to 16-, 24-, 30- or other color depth, you need to resample
the image before saving as GIF. Software like SnagIT and presumably FullShot
(it's been a while, so I don't recall) should let you resample your color
depth at the time of capture. In short, the color thing is a limitation of
the graphics format, not your capture software. (Also, if you are not
optimizing your color, I suspect you are not optimizing your resolution and
it might be that you can slim-down your image sizes considerably.)
And, I use SnagIT32 (registered version not the perpetual trial) . . . and
am very happy with the purchase. I recommend if you need a tool for
business, you purchase the tool (it's a golden rule thing for me, I write
about software after all ;?).
I use FullShot. I think it does a decent job, once you turn off all
the dumb
default stuff that shows up on your title bars. Well, I find it
annoying,
but others might not. I think FullShot does a decent job though. The
only
trouble I've run into is saving images with many colors as .gifs.
FullShot
tells you there are too many colors, etc. So, I end up saving as a
.png.
Currently, however, I'm using a shareware screen capture tool called
SnagIt,
which you can download from www.techsmith.com. I think it does a
pretty good
job, and has a few handy features, such as being able to capture a
scrolling
region and being able to send captures straight to the printer.
