Subject:Re: Screen Captures in UNIX From:Mike Starr <writstar -at- WI -dot- NET> Date:Mon, 20 Oct 1997 06:17:53 -0500
If you've saved your screen captures as bitmap files, try this:
Open the file with Windows Paintbrush (yes, the one that comes standard
as part of your Windows installation). Select the File/Save as... menu
item. Set the File Save As Type to 16 Color Bitmap and save the file,
either under a new name or replacing the current file. What this does is
map the colors to the standard Windows screen colors. Now, select the
File/Open menu item and open the file up, even though you've already got
it open. The reason you need to do this is because the image currently
open is a 256- or higher-color image. You need to open the 16-color
Once you've got the file open, you should have much less trouble
remapping the colors.
Having said all that, my own technique for screen captures is to strip
them completely of color and/or grayscale. I turn them into pure
monochrome images so that no matter what printer I output them on
they'll look the same. In addition, you don't have the degradation
inherent in the photocopying process if that's your production method
for documents. I've found that I can usually strip the color out of a
screen capture in less than three minutes for all but the most complex
Photoshop is a great tool, but I've never found a tool that I can use as
easily as Windows Paintbrush for screen captures. Now, I'll confess I
haven't looked at it since version 2.something so I may revisit it in
the near future as well as installing the version of Paintshop Pro and
Adobe Illustrator that I've ordered. Microsoft Flash might also be worth
Hope this helps
