hello dear opensuse-fans
how to view photos and to rapidly change the major categories
i have several hundred images (photographs) taht i want to view on opensuse linux version 13.1
i want to view the images - and of while doing so i want to turn the colored images into b/w
Question; which is the best - ie. the quickest way to do so.
note; i have installed the following thigns on my opensuse 13.1:
- gimp the great grahical tool
- digicam - the great tool to view images and pictures
- Gwenview Version 4.11.4 on KDE 4.11.5
so again here the question: which tool allowes to view the color(ed) image and to turn it - on the fly - in to black and white?
BTW: can i tell linux to swith the colors - in general - to black and white? is this doable...
looks like we could write a small shell script, utilizing imagemagick.- maybe like this:
this is just a quick hack. i haven't tried it. also, it's not interactive and simply changes all jpg's to grayscale, even if they already are grayscale.
btw we need more information about imagemagick.
see the results:
what can i do!?
