Martin’s Picture Viewer (Mapivi) is a cross-platform, open source picture manager and organizer. It is a standalone tool and does not use a separate web server, online access or a database.
This application copes admirably with EXIF data (like timestamp, camera model, focal length, exposure time, aperture, etc.), and can rename pictures according to their internal date/time, to display and modify JPEG comments and do lossless rotation.
The idea of using Mapivi as an picture organizer is to keep user, EXIF, and IPTC information where it belongs — in the pictures — as well in a searchable Mapivi database. The support for IPTC is particularly impressive.
Mapivi can also perform image processing. Mapivi serves as a graphical frontend for many proven command line tools, such as the Image Magick tools.
Features include:
-
- Supports any existing folder structure.
- Stores just picture meta information (IPTC, EXIF, comments, …) in its database.
- Supports pictures on removable media (CD, DVD, USB-HD, …)
- IPTC/IIM information (International Press Telecommunications Council Information .Interchange Model) with keywords, categories, location, headline, caption/abstract, writer, …:
- Display IPTC.
-
- Add, edit, remove IPTC (also multiple pictures at once).
-
- Hierarchical IPTC keywords and categories.
-
- Apply or save IPTC templates.
-
- Rating of pictures using the IPTC urgency flag.
- EXIF (EXchangeable Image File) information (date, time, aperture, exposure time, ISO speed, …):
- Display EXIF.
-
- Copy EXIF.
-
- Save and restore EXIF.
-
- Remove EXIF.
-
- Alter EXIF date/time absolute or relative.
-
- (Re)build, copy, rotate EXIF thumbnail.
-
- Reset/clear EXIF orientation flag.
- JPEG comments (single and multiple comments are supported):
- Display JPEG comments.
-
- Add, edit, copy, join or remove comments.
-
- Add comments to multiple pictures without overwriting the existing comments (e.g. to add a copyright notice to many pictures at once (batch processing). Without overwriting the existing comments.).
