shown on the screenshots page.

By the way, in my Grouping sidecar extensions, the default entry was:

.jpeg;%raw;.xmp

I assume %raw is a shorthand that knows about most raw file extensions, since
it was already grouping my .jpg and .mrw files under one list entry.  Is
that a correct understanding?

I'm lazy, so here's my blind guess at what you want:
1) Hit u to split the screen
2) In one half, select the foo.jpg + .mrw entry.  This will show the .jpg
3) Click on the other half of the split screen
4) Click the + sign to the left of the filename to expand it
5) Click on the foo.mrw entry, which will show the raw file

HTH,

 Thanks so much!  I really appreciate the explanation.  I was assuming that
 the two images would somehow appear on the split screen in one operation
 which I wasn't able to figure out.

 It looks like the raw image is not actually decoded but that an embedded
 jpeg within the raw file is extracted and displayed.  Am I correct in this
 understanding?

Yes, Geeqie reads only the embedded preview images.

The idea behind it is that full raw processing is too slow to be done on 
demand and it is better to process raw files in a separate script and 
then use the grouping  feature in Geeqie.

Correct.

%raw in expanded to a list of all extensions which are marked as RAW image
in the Filtering tab in configuration.

Re: [Geeqie-devel] Question regarding raw files

2009-02-02 Thread Greg Troxel

  I am sorry I wasn't clear.  I took a look at the screenshots page on the
  geeqie wiki:

  https://sourceforge.net/project/screenshots.php?group_id=222125

  and I see an example where the screen is split and the .jpg and the .cr2
  raw versions of the same image are both displayed.  When I run geeqie, I
  see a single thumbnail with the tag filename.jpg + .mrw, but I cannot
  discover any way to get both images displayed in the split screen as is
  shown on the screenshots page.

I can't answer your question, but have another one: What do you expect
to accomplish from this?  Is geeqie actually doing raw conversion on the
fly from the .cr2 to make bits to show?  When I view raw (.nef) in
gqview it just grabs the JPB BASIC that is embedded in the raw and shows
that.  So what's going on when you look at raw in geeqie?

I find JPB BASIC often good enough, so when I shoot raw I use raw only
and then extract BASIC and delete the raw for files I want to keep that
way, and keep a few raw shots.  I have an not-100%-baked exiftool script
for this.  I have no clue if cr2 files have the same embedded jpg.)

#!/bin/sh

f=$1

if [ ! -f $f ]; then
echo $f does not exist
exit 1
fi
jpg=`echo $f | sed -e 's/\.nef$/.jpg/' -e 's/\.NEF$/.JPG/'`
if [ -f $jpg ]; then
echo $jpg already exists
exit 1
fi

# extract embedded JPG (typically LARGE BASIC)
exiftool -b -JpgFromRaw $f  $jpg

# Copy exif information to jpg
#
# NOTE:  -overwrite_original results in a JPEG file that has the same
# modification time as the the NEF.  At first, this seems desirable (mimicing
# what you'd get straight from the camera if set to NEF+JPEG mode).  But,
# it's probably better for the JPEG's modification time to be the time at
# which it was extracted, thus giving an indication that the JPEG file wasn't
# actually created in the camera at the same time as the NEF.  This behavior
# is obtained with -overwrite_original_in_place.

#exiftool -q -overwrite_original -TagsFromFile $f $jpg
exiftool -q -overwrite_original_in_place -TagsFromFile $f $jpg
