Feature requests?

Hi,

After experimenting with iphotoexport, I failed to accomplish the
following:

1-) Exporting photos that are in the library, but not included in any
album. My iPhoto library is quite large and I believe that are
photographs which have not been placed in any album. How could I
export these?

2-) Avoiding duplicates in the export folder. I have a number of smart
albums that partially overlap. When I experimented exporting some of
these, I noticed that for some photographs, iphotoexport creates
aliases of the actual photographs, but for others the photograph is
copied multiple, one for each album in which it appears. My interest
in using iphotoexport is to embed all metadata in the files
themselves, so simply exporting everything as links is not an option
for my intended use.

Considering the above, I believe many users would find it useful to
have the possibility of exporting the entire library with associated
metadata and placing the exported photographs at the root of the
export folder, thus avoiding duplicates (an originals folder could be
created for photos that were edited in iphotos).

Is there a way of accomplishing 1 and 2 using the current version?

Thanks,
Andre

Update on post above:

If what one wants is to embed metadata in the EXIF fields of all
photographs in the library by exporting a copy of each photo, but does
not care about re-creating the albums organization in folders, it is
easy to:

1-) Create a regular album in iPhoto, called say EntireLibrary
2-) Drag all photos to this album
3-) Use iphotoexport with options -k -a "EntireLibrary" to export all
photographs to a chosen folder

This solution should avoid duplicates as all photos as copied to the
same destination folder. When I attempted to implement this strategy,
it worked for several photos, but for others I got errors like this:

Error: File format error - /Users/afs25/iPhotoExportFolder/
EntireLibrary/Asthenothaerus maxwelli drawing 001.jpg
Error: Format error in file - /Users/afs25/iPhotoExportFolder/
EntireLibrary/Asthenothaerus maxwelli drawing 001.jpg
Failed to update IPTC data in image /Users/afs25/iPhotoExportFolder/
EntireLibrary/Asthenothaerus maxwelli drawing 001.jpg: 0 image files
updated
1 files weren't updated due to errors

For each of these errors, an alias to the photograph was created in
the export folder. I have no idea what causes this error or how to fix
it. After several of these errors as well as successful exports, the
routine failed with this error:

Traceback (most recent call last):

Any ideas of what I am probably doing wrong? Thanks in advance,

Do you have iPhoto configured to not copy photos into your library? If you do that, the original images in your library are just aliases to the real image file. The way iphotoexport copies images, it actually copies the alias, not the file. And then the meta data update fails, because it can't handle an alias. It works for images that you have edited, because then the modified file is actually stored in the iPhoto library. I actually noticed that once before, but didn't follow up because I always check "copy photos into your library".

The fix is easy, if you don't mind modifying the Python script, you can do it yourself. Around line 154 of iphotoexport.py, you find this code:

      # 'cp' is about 4x faster than shutil.copy2() when I tested it a long

      # time ago, but it requires a subprocess

      # shutil.copy2(source, target)

      result = su.execandcombine([ 'cp', '-fp', source, target ])

      if result:

        print >> sys.stderr, "%s: %s" % (su.fsenc(source), result)

Switching it around to use the slower shutil.copy2() will cause it to not copy aliases, but rather the file the alias points to:

      # 'cp' is about 4x faster than shutil.copy2() when I tested it a long

      # time ago, but it requires a subprocess

      shutil.copy2(source, target)

      # result = su.execandcombine([ 'cp', '-fp', source, target ])

      # if result:

      #  print >> sys.stderr, "%s: %s" % (su.fsenc(source), result)

Thank you. That is indeed the case. When I first configured my iphoto
library, I chose not to copy the files. I tried the fix you suggested,
but got an error message informing the "global name 'shutil' is not
defined. Traceback below:

File "./iphotoexport.py", line 720, in <module>

Thank you for your help!

Sorry. I forgot to mention that you also have to add an import statement in line 22 of iphotoexport.py:

import os

import re

import string

import sys

import shutil              <-- add this line

import unicodedata

Thanks. Now the script produces output and in the export folder I find
copies of the photographs rather than aliases. However:

1-) During runtime numerous of these errors are issued:
Error: File format error - <filename>
Error: Format error in file - <filename>
Failed to update IPTC data in image <filename>: 0 image files updated

1 files weren't updated due to errors

2-) Using exiftool -list <filename> to check what was actually written
to the files copied by shutil.copy2 I get:

- for files that are actually contained in the iphoto library it works
nicely (Keywords are copied to EXIF tag Keywords and Comments to EXIF
Caption-Abstract)

- for files that are store elsewhere in the hard disk and only linked
in the library, the EXIF fields of interest appear like this (Tags
written by the camera are erased and neither comments nor keywords are
exported):

That is really odd. I'll experiment a little more with this configuration. Would you mind sharing one of your pictures with me? That might make it easier to debug. Exiftool is actively maintained - maybe there is a newer version available that can handle your particular image. E-mail the image to tspo...@gmail.com. I will use it only for debugging, and then delete it.

Thanks

Tilman
