Retreiving image metadata

Can anyone point me on how to retreive image metadata from an image... I was looking into the possibility of using JAI but could not find a clear answer.... If some one could post a link or point me in the correct direction...
Thanks in advance....

How to retreive images and xml stored in temporary internet files

hi all,
I am creating an air application that has to work in offline too.so i have decided to retrieve datas it from temporary internet files(is it a rightway or anyother way to do that if so pls suggest). I have an issues of retreiving images and xml stored in the temporary internet files of the user system ..can anybody help me and give solution for this..
regards,
Divya.

What software are you using to create the website? Perhaps there is some command you can implement on the website to force the entire file to be downloaded. If you use Dreamweaver, you might ask in that forum. If you make the link an ftp link rather than a http link, you might guarantee that the file will be downloaded in its entirety, but the download location will not necessarily be in a temp folder.

Update image metadata programatically

Hi
I developed a plugin, which changes exif information of the image (using a third party program). Is there a way to inform Lightroom programatically to refresh image metadata? Right now I have to right-click on the folder and choose "Synchronize Folder...".

There's at least one ODBC driver for SQLLite http://www.ch-werner.de/sqliteodbc/, and maybe command line access to the database too
But there's nothing directly through Lightroom, and you won't be able to code Lightroom to refresh EXIF data. There is no coding mechanism to write to EXIF fields or to refresh the image (ie sadly you can't automate Metadata > Read Metadata).
If you write directly to the SQL while LR is open, the best you can expect is that the EXIF will use updated data from the database when you next click on that image in Library. However, you are likely to encounter database locking problems and stand a good chance of corrupting the database. Abandon all hope, ye who enter here?

Muse image metadata and global caption styling

When will Muse be able to import image metadata and perform global caption styling with accurate positioning for lightboxes and slideshows?

I've done some testing.
if images are uploaded to the Facebook Wall, the Comments field that Aperture presents before uploading the image becomes the Description field on Facebook.
however, if the images are uploaded to a known Facebook Album, the Version Name becomes the Description.
both of these situations are not logical. in the case of uploading to the Wall, 'Comments' should probably be 'Description'. I'll report them to Apple's bugreport.
images seem to be scaled down to fit within 2048x2048 pixels.

Reading Image Metadata..

Hi,
I am converting some PHP pages to JSP. There is an image gallery page where images are being displayed and also the comment and Author names is displayed under that image.Those things are set as image metadata.
The code for doing this in PHP looks like....
$exif = exif_read_data($full_file_path, 0, true);
foreach ($exif as $key => $section)
foreach ($section as $name => $val)
echo $section['Comments'];
echo $section['Author'];
How can I achieve this in java i.e. how can I read author and comment metadata fields using java....
Thanks & Regards

Image metadata is not retained(stripped) in lightbox slideshow widget

How is this corrected

Can someone at Adobe please confirm that there is no reading of the image metadata. I thought it was limiting that it was only the caption field available. I am stunned if this is the case that no metadata is being read. I am working on a photo web site and got to the point of importing photos with the 'captions' checked. Huge surprise. It is hard to believe that something as fundamental as basic metadata fields (caption, title, filename, copyright) isn't pulled with the image and available as needed. C'mon, you are the company that has Photoshop and Lightroom. Do you guys talk to the other teams?
I was looking at Muse galleries as an alternative to the LR web module for 2 reasons: one is flexibility in layout, and the other is speed, since the LR gallery export cranks along at a glacial pace to the point of being almost unusable. And this is the LR4 upgrade; much slower than LR3. See the LR threads on this if you're interested. Still waiting for that fix.
The thought of manually entering caption info to a dozen galleries, each with 20 or 30 images, is nonsense. This makes Muse a non-starter for photo galleries. This is basic capability. Adobe should be embarrassed that LR4 doesn't do what it should in this regard, and that the feature needed don't even exist in Muse. Everyone expects a few bugs in the early days of a new software, but not missing essential, fundamental features to make web galleries useful.
Rant now over and I will happily apologize if the metada fields are, indeed, available. Please explain how. Thanks.

Image Metadata Editor

I have been looking for inserting descriptions into my pictures. Unfortunately, there isn't any option to edit Metadata in File Explorers (I tried Thunar and Nautilus). I wouldn't like to have a photo gallery software just to do that, and, by the way, I couldn't find any of those that allows me to edit metadata in a straight-forward way. I have to navigate through a lot of menus in order to do that.
Basically, I was looking for a plugin or other software that enhanced the "Image" tab on Thunar, so I could see and edit all file metadata there. Honestly, I don't know how do you guys keep your photo albums organized without this feature.

I've found Shotwell pretty straightforward to edit tags. However, I personally also use feh + dmenu + a script I found somewhere to view and edit metadata. The latter method I find quite speedy when I've imported a bunch of photos. The script is
image-metadata.sh:
#!/bin/bash
if [ $# -lt 2 ]
then
echo -e usage: "$0 <action> <filename>\n actions: edit-comment, edit-tags"
exit -1
fi
action=$1
file=$2
if [ "$action" == "edit-comment" ]
then
commentText=$(echo | dmenu -t "$(exiv2 -Pt -g Exif.Photo.UserComment $file)")
if [ $? -ne 1 ] # not aborted
then
if [ -z "$commentText" ]
then
exiv2 -M"del Exif.Photo.UserComment" $file
else
exiv2 -M"set Exif.Photo.UserComment $commentText" $file
fi
fi
fi
if [ "$action" == "edit-tags" ]
then
exiv2 -Pt -g Iptc.Application2.Keywords $file > /tmp/._image_keywords.txt
selection=$(exiv2 -Pt -g Iptc.Application2.Keywords $file | dmenu -sb "#000" -nf "#aaa" -nb "#222" -sf "#509ba6" -fn 'Deja Vu Sans Mono-14:bold' -l 10)
if [ -n "$selection" ]
then
exiv2 -M "del Iptc.Application2.Keywords" $file
while read keyword
do
if [ "$selection" != "$keyword" ]
then
exiv2 -M "add Iptc.Application2.Keywords String $keyword" $file
else
deleted=true
fi
done < /tmp/._image_keywords.txt
if [ -z $deleted ]
then
exiv2 -M "add Iptc.Application2.Keywords String $selection" $file
fi
fi
rm /tmp/._image_keywords.txt
fi
if [ "$action" == "show" ]
then
comment=$(exiv2 -Pt -g Exif.Photo.UserComment $file)
exiv2 -Pt -g Iptc.Application2.Keywords $file > /tmp/._image_keywords.txt
echo -n Comment: $comment, "Keywords: "
first=true
while read keyword
do
if [ $first == "false" ]
then
echo -n ", "
fi
echo -n $keyword
first="false"
done < /tmp/._image_keywords.txt
echo
rm /tmp/._image_keywords.txt
fi
It requires exiv2, iptc, and dmenu. (Also ttf-dejavu, but you can edit out that font choice ) The script is not mine; unfortunately, I cannot remember where I found it.
Then in .config/feh/themes, put
tag --action2 ";/path/to/image-metadata.sh edit-comment %f" --action1 ";/path/to/image-metadata.sh edit-tags %f" --info "/path/to/image-metadata.sh show %f"
Browse pictures with "feh -Ttag *.jpg" for instance, then press 1 to edit tags, press 2 to edit comments.

How do I edit image metadata?

What I would like to be able to do is something like:
  tell application "Image Events"
  tell pic
    make new metadata tag with properties {name:"creation", value:cr}
  end tell
  end tell
Only, sips/Image Events doesn't support setting most image metadata. Any suggestions as to how to approach this problem?

Thanks. Lightroom 2.4, unfortunately, isn't very scriptable. This is ironic, since the program itself relies on Lua for its interface functionality. I will probably, eventually, manage to compile Exempi and the Python XMP Toolkit and do the job that way.

WDS 2012 Image Capture - Stuck at 50% "Capturing Windows image metadata..."

I have tried capturing a few images after running sysprep, and they are getting stuck at 50% completion, never moving past after hours of waiting. "Capturing Windows image metadata...". If I look on the WDS server I see that the file
hasn't been modified since it was actually capturing and moving the progress bar.
Has anyone ever experienced this, or have any ideas of how to troubleshoot?
Thank you!

Hi motenoob,
What system edition and MDT edition you are capturing? If it is Windows8 or 8.1, it seems is the know issue, you can refer the following KB:
Sysprep and Capture task sequence fails when it tries to capture Windows 8 or Windows 8.1 images

Access Image Metadata

Hi!
I'm attempting to create a photo uploader as part of a school project, and I was wondering how I can access, and edit, the metadata for the images I'm uploading. I want to change the tags, description, etc. I tried Googling, but it didn't return anything I can use.
I also suspect it might not be possible to edit metadata in Flex. If so, is there another way I can do this?
By the way, I'm using Flash Builder 4.5 Premium, with Flex 4.5.1 SDK.
Cheers
Mark

I've not tried this but it looks promising

Check image metadata in Oracle Forms 6.0

Hello,
I need to check if an image selected by the user in a Form has the EXIF format because, if so, I need to convert it (using an IrfanView command) before persist it in the database.
I am developing using Oracle Forms 6.0 and Oracle 9i. Do you know if there is a way to check an image metada data inside the Forms.
Thanks for answering.
David

You can also verify EXIF on client side with java (before you post image into database) (Java plugable component) ;)
some libraries...

Or you can also make Java stored procedure on database side...

How can I view only UNSAVED images/metadata?

I rotate photos in bridge, but these metadata changes are not saved to the actual image until saved in Photoshop. If I missed saving a few photos during my initial steps, how will I know which photos still need to be saved if i can only see the modified files? I need to give final images to client and if the changes aren't saved, all the photos will be oriented wronged. is the only way to resave the entire folder with image processor? is there a way to view only unsaved files so only those need to be processed? i don't want to resave files unnecessarily - both for time's sake and for quality sake. In Lightroom there's an option to save metadata changes to file automatically. And even in Google Picasa, you can just hit save to save all modified files.
It seems there's no save button in Bridge and no way to know which files need to be saved. Can somebody help me out with this please?

and i will add that i think it's a huge flaw to not have an option to save/export files properly. sure, professionals prefer metadata because it does not affect the original. but software developers have to remember that professionals have clients. and clients need their things to work out of the box. i don't want to field technical support calls for avoidable circumstances.
(stationtwo - i feel you didn't read the orignal post; i'm really not sure where i'm losing you. do you not understand that professionals have NON-professional clients? we scan and edit family photos using Bridge and Ps to create a final product given to home users.that final product (a DVD filled with their edited family photos) needs to be compatible with all platforms OUT OF THE BOX! it's like giving someone their movie on a DVD+R which won't work in an older DVD-R player. DVD-Rs are more compatible. It's stupid to tell a client they need to buy a new DVD player. It's the professionals' job to make sure that their clients don't run into these issues. and it's the software developers' job to have the foresight to prevent compatibility issues in the first place. )

No image Metadata when outputting from Bridge Web Gallery (CS4)

I use the Web Gallery option within the Output module in CS4 Bridge to process my photos to the image size I want for uploading to flickr. However all the metadata data gets stripped out.
Is there an option I am missing to retain metadata?
Of course I can add back in any IPTC data I want, but I should not have to do that more than once, what I am really annoyed over is the Camera Data (EXIF) is gone.
Software Details:
CS4 Bridge (3.0.0.464)
Output Module
Web Gallery (Standard or HTML Gallery)
Mac OSX 10.5.7

Look into the Image Processor in Bridge or, better yet, install Dr. Brown's Services 2.0.2, a free, brilliant set of scripts by the same author as the Image Processor, Russell Brown. It's like the Image Processor on steroids.

PDFs appear with fragmented images, metadata missing

Can anyone help with this one?
We use InDesign CS3 to create PDF 1.6's, directly from InDesign export. The metadata contained in the images on the layout normally are visible when you control click and select "show metadata" on the image in the resulting PDF with Acrobat's touch up object tools. Ocassionally, there is an unknown problem in the process where a given image will "fragment" -- when you click on it in the PDF, a frame surrounds only part of the image, and there's no "show metadata" choice to select. This is kiling us because we doconstruct those PDFs and put them into our long term archive, and the metadata is missing there!
Any help would be appreicated!
Thanks.

Sounds like some type transparency flattening going on in there. InDesign itself has issues when exporting to lower PDF versions (1.3) and also if transparent objects are around say hyperlinks/buttons etc. The XMP data can be destroyed since it's been broken down and is not the original content any more.
Let us know if you explore in more detail in the ID forum, 2 doors down

How to access Image Metadata with AS3?

An image, like a jpeg, has a bunch of metadata stored in it.
The "IPTC Core" metadata usually includes the photographers name,
address, title, description, etc.
Is there any way to access this information using AS3 so
that, say, captions for images in a flash gallery could be
generated automatically?

As far as I know this is not possible with AS3 directly, but
if you are interested you could check out the as3corelib at
http://code.google.com/p/as3corelib/
They have some pretty nifty JPEG things going on there
(although I do not know if this includes metadata - but I hope
so).
