I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.

Need to extract -PreviewImage with -Orientation tag
Hi friends. I need to extract from from a dir with nef files the -PreviewImage with -Orientation tag After many reading all about exiftool, I have been trying to do it in one command line but not success at all.
exiftool -fast -b -PreviewImage -w nef.jpg -ext nef DIR (this works ok)
With the above command I can get files -PreviewImage "file#.nef.jpg" from "file#.nef" but without -Orientation tag
And with a second command I try to copy -Orientation tag from nef files "file#.nef" to the new "file#.nef.jpg" but no success.
exiftool -fast -overwrite_original -tagsFromFile %d%f.nef -Orientation -ext nef.jpg DIR (this not working)
If it is posible to do it with only one command line, will be great.
Please, can you help me? I need to do it with only one command line, if it is possible.
Thanks in advanced for this wonderful exiftool.
My best regards.

Re: Need to extract -PreviewImage with -Orientation tag
This is a bit tricky, but you can use the -execute option to combine different commands into a single command line. I think this may do what you want, but I can't test it right now to make sure I didn't do something wrong:

exiftool -b -previewimage -w nef.jpg -ext nef DIR -execute -tagsfromfile @ -orientation -srcfile %d%f.%e.jpg -ext nef DIR

Re: Need to extract -PreviewImage with -Orientation tag
I tried this with a pef-file and it works generally, but errors are displayed. Error: File not found *pef.jpg. Also I used -w pef.jpeg, because I like to have the extension jpeg and not jpg. It allows me to delete all _created_ files, which use jpeg, while original jpg-files are untouched.

Hi friend.

Thanks a lot, Phil and Linuxuser for your prompt reply.

Yes, it is tricky and I use it from a Java program with "Runtime.getRuntime().exec(exiftool_command);"

I have dirs with a mixture of NEF and JPG original files and I need to get 256x256 thumbnails of them with the right orientation.

The jpg files I get with this code are intermediate to get 256x256 pixels thumbnails with "mogrify", so after I need to delete those intermediate .nef.jpg

Phil, I am going to test your proposal with needed variations, I will let you know about, sure :-)

Linuxuser, you had a nice idea, I use nef.jpg to be able to differentiate them from original jpg, but it could be also just .JPEG so I will not need a double extension.

I will comeback as soon as I have some results after testing with these new possibilities.

Phil, thanks a lot for this very nice exiftool. I will let you know about my program for photography classification.

My best regards.

P.D. Escuse me about my english, I am from Spain :-)

Re: Need to extract -PreviewImage with -Orientation tag
Hi Phil and Linuxuser.

I think I have found the coding solution for my program, I am very happy :-))

"exiftool -b -previewimage -w jpeg -ext nef . -execute -overwrite_original -tagsfromfile %d%f.nef -Orientation -ext jpeg ."

I made test with nef files but it will be like: cr2, raf, rw2, jpg as original from cameras.

With this one a get the previewimage of any raw file with the right orientation tag in it and with JPEG extension, so I can delete JPEGs after "mogrify" reduced them to PNG with 256x256 pixels without afecting originals jpg in the same dir.

Thanks a lot Phil and Linuxuser, both have guide me to the nice solution.

Muchisimas gracias :-)

My best regards.

P.D. I will keep you inform about my photo clasification system that is universal because it only use pure text files to keep photo tags and Java.

Re: Need to extract -PreviewImage with -Orientation tag
Great. Glad you figured this out. My command line didn't work because I needed an extra "." as in -w .nef.jpg

Re: Need to extract -PreviewImage with -Orientation tag
Can you explain with a few sentences what your photo clasification system does?

Re: Need to extract -PreviewImage with -Orientation tag
Hi Linuxuser.
Of course I will try to explain how I classify photo originals. It is a system for personal use with some thousand photos per year, but not for photo agencies. It +will be full free with some kind of GPL/Copyleft. HardDisk |__MyPhotos | |__2007 |__2008 |__2009 |__090110_After_Christmas |__090125_Another_sesion |__... |__090519_Last_photo_work |__autor_090519_1234.raw |__autor_090519_1235.raw |__auror_090519_1236.raw |__... |__090519_Las_photo_work.dat |__thumbnails |__autor_090519_1234.raw.png (255x255pixels) |__autor_090519_1235.raw.png |__... The data file: 090519_Las_photo_work.dat (pure text content) 0 common tag words to all photo of this session 1 autor_090519_1234.raw particular tag words for this photo as many as you wont 2 autor_090519_1235.raw particular tag words for this photo as many as you wont 3 autor_090519_1236.raw particular tag words for this photo as many as you wont 4 ... Until now I have some years clasified with this system using just standar text editors and standar +OS searching possibilities, but now I have programed this GUI to make it easy. The programa: Organizing: (Sessions) Rename photos in a session with the escheme: autor_yymmdd_####.ext extracted from exif data, autor +is in program config. Create png thumbnails 255x255 with right orientation. Classifying: (Sessions) Display a list of session photos and a text box where to write tags with nice easiness. Searching: (all sessions, a year, one session) Search for photos with a boolean combination of tag words and you see thumbnails of results. If double click in a result word jumps to Classifying with the session of the click photo. If double click in the thumbnail, jumps and opens the photo with Gimp or any other photo editor. Histogram: (word histogram) In two lists -Alfabetical order and -Quantity order. If double click in a word jumps to Searching w +ith that word. When hard disk are full, you have the thumbnails to see the photo, DVD are tittle with just 090110_ +090119, so you know which sessions and photos are in that dvd. The system and program name is: "Siaclafo" Sistema Abierto para Clasificacion de Fotografia. Open S +ystem for Photo Classifying. Advantages: It can work in any Operating System, any version now and in the future. Just pure text, + everybody can easily see and edit. Actual test speed, PC Linux, single CPU 2.8 Mhz: Average searching time in a tree with: 3 Years, 50 +0 Sessions, 5000 photos, 730 diferent tag words = 12 seconds. Please, ask anything you like. Best regards.
