CopyExif.Exe
Command Line Tool
|
|
Overview:
This tool takes a source image and destination image and adds any Exif
data in the source image that is missing from the destination image.
I wrote this tool because someplace during my workflow of handling images
I've been losing Exif data. For any decent picture I keep the
original raw formatted, and this tools, most of the time, will restore the
missing data to the final image that I end up posting. I did not
have a significant problem until I started using Digital Photo Pro from
Canon, for canon raw cr2 files, which habitually strips the exif
information off before producing a JPG.
Notes:
- The input files can be canon CR2 or JPG.
- The output files must be JPG
- Currently the output files must be encoded with Intel little
ordering or the tool can't correct the Exif information in the
output file.
- I'm half tempted to add a command line option that says
trash the big endian formed data and replace it, but alas I only
have a small percentage of files that suffer from this so I have
not made the coding change (yet). I'm going to first see
if I can find the tool that doing this and see if there's a way
to make it stop.
- If you supply directory names instead of filenames, the tool
will look for all matching JPG files in the destination directory
and compare each one. E.g., you can fix a batch of JPG files
at once.
- There is a special case of ".." that can be used on the
destination name. This will tell the app to check for
matching destination JPG images in the parent directory of where
the current source image is located. I did this because
that's the way I have some very large photo database setup.
- No warranties are implied. The tool is primarly made to
correct files coming out of Digital Photo Pro and that's what it
does. If it works somewhere else great, if not.. maybe it
can be extended but remember the price was free :).
- Note that Exif encoding sort of sucks. Many fields are
position dependant, and to add back what's missing things must
move, so if you don't understand some position dependant field
it's rather hard to move it. The tool handles the ones
I've encounter.
- Feel free to make fixes to the source code and email them back
to me for inclusion so others may benefit as well.

Usage:
|
|
|
CopyExif
|
[-ruox] [-v1..f]
Source Destination |
| |
|
|
Source |
The source image file, or source directory. |
|
Destination |
The destination image file, or destination directory |
|
|
|
|
-r |
Used when supplying a Source & Destination directory.
Recursively walks the Source directory looking for images, and checks the
matching directory tree in the Destination directory looking for target JPGs
to fix. |
|
-u |
The default operation will only add missing Exif data items
to the target image. This flag causes Exif items that are in the
target image to be replaced if the have a different value in the source
image. |
|
-o |
Overwrite all. Causes Exif data items in the target to
be removed that are not present in the source image. |
|
-t |
Removes the embedded jpg thumbnail in the target image.
(The tools I'm using aren't using them, so might as well pull them out). |
|
-s |
Save the original JPG file. This leaves the original
JPG in a file with the extension of ".old" |
|
-x |
Don't perform any updates. Just scan and show what
would be done. |
|
-v1..f |
Sets the verbose flag to the hex value. |
|

|
CopyExif
original\img_123.cr2 post\img_123.jpg
|
Copy Exif info from all the files in the folder original to the
matching files in the folder post
Copy Exif info from all the files in the folder-tree original to
