Printing color with xwd

Today, this is (relatively) simple: you'd do something like:

xwd | xwdtopnm | pnmtopng > Screenshot.png

But it does seem odd that it takes so many steps. See How do I capture program screens to a file or print them? for capturing screens in other environments.

well, for me:

        gv /usr/local/share/ghostscript/5.10/examples/colorcir.ps

shows a color image, and,

        xwd -out /tmp/tst.wd
        gimp /tmp/tst.wd

shows a color image, but,

        xwd -out /tmp/tst.wd
        xpr -device ps -output /tmp/tst.ps /tmp/tst.wd
        gv /tmp/tst.ps -landscape -swap

shows a black and white image.

therefore, I'm pointing my finger at xpr not producing a color ps in the
first place. So you need something else besides xpr to make the ps, and
this may mean you need something other than xwd to grab the image unless
you can find another scriptable util that can read xwd output. Look into
ImageMagic for starters, and maybe gimp or xv can be run
non-interactively too. both of those can read xwd files, and output
color ps files. but it requires mouse clicks from a human being.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
