changes:
added -cl (insert comment literal) option
Added -norot (zero out rotation tag) option
Added handling of explicit 35mm equivalent tag
Added ability to do sequencial renaming
and fixes
Changes since 1.9:
Minor changes where newlines are printed.
Added check to warn about wiping out the originals with the -st option.
Fixed display of "flash used=no" for exif headers generated by photoshop.
Added -ci and -cs options.
Limit directory recursion depth to avoid crashing on circularly linked
directories within the Exif header.
Added automatic rottion (-autorotate) to right-up images that contain
a rotation tag from the camera.
*Finally* wrote a nice MAN page for jhead.
Makefiles simply need to use this value often, for better or for
worse.
(2) Create a new variable FIX_RPATH that lists variables that should
be cleansed of -R or -rpath values if ${_USE_RPATH} is "no". By
default, FIX_RPATH contains LIBS, X11_LDFLAGS, and LDFLAGS, and
additional variables may be appended from package Makefiles.
changes:
- Ignore undefined bits of "flash used" tag, as cannon sets them nonzero,
causing jhead to indicate flash used when it wasn't with some Canon models.
- Automatic rotation using jpegtran & clear rotation element
- Option to put a file in as comments (as opposed to edit file)
This adresses pkg/17816 by Eric Jacoboni
Changes since 1.5:
- Added -V (version) option
- Added -exonly (exif only) option
- Fixed lots of typos (Thanks, David Baker [mailto:dave@dsb3.com])
- Use EDITOR environment variable to pick which editor (Instead of notpead or VI)
- Improved thumbnail deletion feature - now not just shortens the header, but
also removes pointers to the thumbnail form the exif header.
site. Changes from the previous pkgsrc version:
1.4 --> 1.5 (Oct 25 2001)
* Minor typos fixed
* Added "-ce" option to edit comments
* Fixed bug in "-ts" option that caused the time set to be incorrect
* Fixed saving of thumbnails for big-endian format cameras
* Wen renaming files to date based scheme, avoid changing names of files
with correct name already.
* Added '-de' option to remove exif header
* Added '-ts' option to set exif timestamp absolutely
used by most Digital Cameras.
Things the 'jhead' program can extract from an Exif file:
- Integral low-res Exif thumbnail
- Shutter speed
- Camera F-stop number
- Flash used (yes/no)
- Focus distance (some digital cameras store this element - very
interesting)
- Focal length (most zoom cameras store their zoomed-to focal length)
- Equivalent 35mm focal length (Calculated from focal length, CCD size,
and CCD resolution)
- Image resolution
- Time and date picture was taken
- Camera make and model
