how to switch the color to black and white <- on the fly

Martin Kaspar
hello dear digikam-experts



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...

love to hear from you

As far as I know this is a broader problem than Digikam. It's a
"feature" of using KDE apps in a non-KDE environment. There was a thread
about this recently and IIRC there is no fix. I also have Linux Mint and
have other applications that exhibit the same problem. I'm hoping I am
wrong, BTW!

Well, I use Linux Mint as my OS as well and I have Widget style set to
"GTK+". This setting is OK, I  can read anything mentioned above.

There are 2 settings which have effects on application colors :

- Widget style.
- Color scheme.

For both, you can add new one using distro installer, but the most
important is Color Scheme. From KDE, there are come from kdeartworks
package.

Best widget style is Oxygen (KDE default). A lots of other styles are
bugous and not maintained...

Subject: [Digikam-users] Viewing and Setting the GPSDestination
        GPS?attributes
Message-ID: <[hidden email]>
Content-Type: text/plain; charset=UTF-8

Hi,

I am a digikam user and really like the functionality that Digikam
provides. Thank you for all the work you as developers invest in the
software!

One feature I am missing and would like to see implemented in Digikam is
the ability to set the GPSDestination EXIF metadata.

I am organizing the photos geographically. The position the photo is
taken is recorded automatically from my Solmeta GPS tagger. However,
more important than the position the photo is taken is the position we
are looking at when taking the picture, esp. in the case of tele-lense
pictures of mountains.

The goal is being able to organize, find and view the viewing angle of
my photos, like in this screenshot of an application I did several years
ago: http://www.carto.net/neumann/temp/geophoto_view_angle.png - see
also http://www.geofoto.ch/geophotomap/ (currently does not work in all
browsers, need to fix a few things). Should work in Firefox.

Now my question:

These destination EXIF metadata needs to be set by hand. Digikam already
has the map view of where the photo was taken. Would it be possible to
enhance Digikam to allow the edition of the GPSDestination metadata.
This concerns the following EXIF tags:

GPSDestLatitude
GPSDestLongitude
GPSDestLatitudeRef
GPSDestLongitudeRef
GPSDestBearingRef
GPSDestDistanceRef
GPSDestDistance

Some GPS tagger device also record bearing data (electronic compass).

Based on the size of the photo sensor and the fov one can then draw a
viewing angle like in
http://www.carto.net/neumann/temp/geophoto_view_angle.png

I am not a developer but I would be willing to pay a digikam developer
to work on the following:

1. ability to edit all of the GPSDestxx EXIF data listed above - both
interactively in the map, but also based on numeric values (line input
widgets)

2. ability to draw the viewing angle on a map like shown in
http://www.carto.net/neumann/temp/geophoto_view_angle.png

Is there a digikam developer out there who would like to work on these
features if I would fund the work?

Thanks a lot for your replies.

digiKam has in Editor and Batch queue Manager a B&W converter which a lots of analog film emulation.

There is also Infrared converter...
