I am using GNOME desktop for my
daily work and I manage photos from my digital camera in Nautilus
commander. There is MINI HOWTO for integrating RAW files to GNOME
2.4 and newer using tools from dcraw
project.
With these files you will be able to see digital camera RAW file
thumbnails in Nautilus and open images by clicking on them.
You can also change the file contents, and use this MINI HOWTO to
add any new MIME-type to the system.
- Install any rawphoho plugin to the GIMP (file names mentioned below
and names in files are valid for GIMP 2.2): either simple Dave
Coffin's rawphoto plugin or nice Paweł Jochym's
RawPhoto or Udi
Fuchs' UFRaw or Joseph
Heled's rawphoto (last two has some Nikon enhancements). For
Minolta cameras you can use Mrwtoppm
plugin, which is not based on dcraw.
- Define
image/x-dcraw mime type. Copy dcraw.mime
to /usr/share/mime-info. It defines this mime type for
suffixes .bay, .bmq, .cr2,
.crw, .cs1, .dc2, .dcr,
.fff, .k25, .kdc, .mos,
.mrw, .nef, .orf, .pef,
.raf, .rdc, .srf and .x3f. If
you have shared-mime-info-0.21
or newer, you can skip this step – raw MIME types are already
defined (basic support was added in shared-mime-info-0.20).
- For the same purpose in GNOME 2.6 and later you need to
define Shared
MIME Info Database entry by copying dcraw.xml
to /usr/share/mime/packages. Then you need to
run update-mime-database /usr/share/mime. Note that
GNOME 2.10 and share-mime-info-0.16 has MIME
sub-class support, which is needed to open for opening RAW files
embedded to JPEG or TIFF like Nikon NEF. This works
correctly since gnome-vfs-2.10.2 (see GNOME bug
171595). For older versions you can want sub-class-less
implementation of dcraw.xml.
- Define standard application for opening RAW files – GIMP by copying dcraw.keys
to /usr/share/mime-info. Let me know more translations (in
current GNOME not yet displayed). Note that gimp-2.2 is
not executable name, but key name from
/usr/share/application-registry/gimp.applications. For
older GNOME applications, edit this file and add
,image/x-dcraw to the end of line with mime_types=.
You should properly install (or link) these files from
/usr/share/gimp/2.2/misc, if your distribution does not do
it for you.
- For the same purpose in GNOME 2.8 and later you need to edit
/usr/share/applications/gimp-2.2.desktop and add a string
image/x-dcraw; to the end of the line beginning with
MimeType=. For newer shared-mime-info, you have to add all
related MIME types – GNOME does not yet support sub-class for
thumbnailers. Then you need to call
update-desktop-database.
- Copy default icon gnome-dcraw.png
defined by keys file to /usr/share/pixmaps.
- For the same purpose in GNOME 2.8 and later you need to copy or
link the icon to file gnome-mime-image-x-dcraw.* in
directory /usr/share/icons/gnome/*/mimetypes,
e. g. by ln -s /usr/share/pixmaps/gnome-dcraw.png
/usr/share/icons/gnome/48x48/mimetypes/gnome-mime-image-x-dcraw.png
(in newer GNOME versions, it is outdated – icons are smaller
here, and also need to be added for all raw MIME types defined in
shared-mime-info).
- Copy dcraw-thumbnailer
somethere to your path. Note that this script requires preview
included in RAW file, It uses dcraw and
gnomevfs-copy. If your camera has small or no RAW preview,
you can use alternative dcraw-thumbnailer,
which uses original RAW data interpreted by dcraw. It is
significantly slower, but can result much better results (thanks to
Mattias Holmlund). Note that these thumbnailers don't work properly
with gnome-vfs-2.10.0 and 2.10.1 (see GNOME bug
172658). If you are using dcraw in rcs
revision < 1.310, you have to use old thumbnailers (dcraw-thumbnailer,
alternative dcraw-thumbnailer)
using parse from dcraw (this binary can have name
dcparse or miss in your distribution, please verify and
optionally edit the script).
- Let GNOME know about your new thumbnailer – copy dcraw.schemas
to /etc/gconf/schemas and generate GConf database entries:
GCONF_CONFIG_SOURCE=`gconftool-2 --get-default-source`
gconftool-2 --makefile-install-rule dcraw.schemas.
- Don't forget to set “Only smaller than” in your Nautilus
preview preferences to proper file size.
Alternative installation to /usr/local directories: If you
distribution sets environment variable GNOME2_PATH to proper value
(e. g. /usr/local:/usr), it's also possible (except
/usr/local/share/mime – there you need variable
XDG_DATA_DIRS).
Note that those paths are valid only for GNOME in /usr
prefix. It can vary on different distributions:
- SuSE Linux ≤ 8.2:
/etc → /etc/opt/gnome2
/usr/share → /opt/gnome2/share
- SuSE Linux ≥ 9.0 and < 10.3 (except /usr/share/mime):
etc → /etc/opt/gnome
/usr/share → /opt/gnome/share
- Self compiled GNOME:
/etc → /usr/local/etc
/usr/share → /usr/local/share
- In SuSE Linux and openSUSE you can find it as a precompiled package
dcraw-gnome
- Latest Fedora package: gnome-dcraw-0.1-1.noarch.rpm
(gnome-dcraw-0.1-1.src.rpm).

Source form of icon is available in XCF
format.
PROBLEMS: RAW files can also have following
suffixes: .jpg, .raw and .tif. It's
impossible to detect RAW file from these suffixes, so it's required
to detect them from contents. Owners of such cameras: Please send me
a magic keys for those files. Mime file: Added most suffixes.
TODO: Small icon (needed for example for GTK file dialog), better
thumbnailer, gdk-pixbuf loader, nautilus RAW EXIF reader. Any
volunteers?
