This is great!

A couple of observations:

The functions (on my mac!) both have an extra "Exif_" in front of the function name

This is intended. The first four letters are treated special by FileMaker. It is the FileMaker PlugIn ID.

Exif_Get_Exif_Reference

and

Exif_Get_Exif_from_File

For Exif_Get_Exif_Reference I can get partial results:

1. in certain cases the full jpeg_reference works, ie

imagemac:/Macintosh HD/Users/me/Desktop/my folder/DSC01950.JPG

works fine.

But I am stumped by the fact that a longer pathname doesn't seem to work

imagemac:/Macintosh HD/Users/me/Dropbox/Base de Dados/GPS Data/26 07/GPS 3/DSC01950.JPG

Is this a real local path or is there some magic with dropbox going on? I tested a longer path on my mac (with blanks) and it works.

Regards Jens

does not work. I am sure this path is correct as its the very same that is used in a calculated container field, and the image is visible in the record.

2. There seems to be a similar issue with Exif_Get_Exif_from_File.

The unix path

/Users/me/Desktop/my folder/DSC01950.JPG

works fine,

but the same file in a different location does not return Exif data. The path

/Users/me/Dropbox/Base de Dados/GPS Data/26 07/GPS 3/DSC01950.JPG

does not work. I have checked permissions and have Read & Write privileges over the file in both locations

Best regards

Hi

When the images are inserted into a database via a conventional container field, the Exif_Get plugin works just fine. However it doesn't appear to work when the container field is a calculated field, accessing images that are resident outside of the database. Is this possible in some way, or a limitation of the plugin?

My apologies if this topic has been discussed here before, but the archive link from the webpage is not working

Hi,

this was indeed a limitation. But I made a new version (for Mac) today: 0.3.0. It has the ability to extract Exif data also from container fields with images stored as reference.

External jpg files are also accessible.

Win version, improved example file and documentation are following soon.

The link is: http://jensteich.de/wp-content/exif-plugin/ExifPlugIn-0.3.0.Mac.zip.

There are two new functions:

Get_Exif_Reference( jpeg_reference ; tag )

which wants a FileMaker container field with jpg images stored as reference as first parameter and the exif tag as second.

Get_Exif_from_File( unix_path ; tag )

this function expects a unix path as first parameter: '/Users/me/Desktop/myfunnypic.jpg'
