The Mapivi application was designed to be an open-source and cross-platform (UNIX, Mac OS X and Windows) picture manager / organizer written in Perl/Tk. Mapivi is a stand alone tool, there is no need for a web server, online access or a database.

Mapivi is a photo management tool with focus on JPEG pictures. Mapivi supports adding, editing and searching of IPTC/IIM, EXIF data and JPEG comments. The pictures are managed in place (in your folder structure), so you are able to use other tools like file managers or other viewers together with Mapivi.

Mapivi is a stand alone tool, in the sense that there is no need for a web server, online access or a database.

EXIF information (like timestamp, camera model, focal length, exposure time, aperture, etc.) are stored in the pictures by digital cameras. Mapivi displays this information in a short and readable format, e.g, "2008-02-21 10:55:30 29mm (43mm) F5.6 1/125s +0.3 ISO200 Nikon D70". It is possible to rename pictures according to the EXIF creation date and to search and browse your photo collection by this date.

IPTC information (like keywords, caption, location, etc.) can be added to pictures using Mapivi. There are several ways to do this: The user is able to define his own hierarchical keyword catalog and to assign one or several keywords to a selection of pictures at once. Other IPTC tags like the caption can be assigned directly in the main window. Existing IPTC location information (Country, Province/State, City, Sublocation) can be assigned to a set of pictures. These and all other IPTC tags can be edited in the IPTC dialog (for one or several pictures at once).

Mapivi also support JPEG comments, but I recommend to use the structured IPTC information.

Mapivi saves all meta information where it belongs to - in the pictures.

When you add a caption to a picture (like "day in the garden with Tom, Tim and Peter") or add hierarchical IPTC keywords (like Nature.Plant.Flower.Rose) this meta information is stored in two places:
1. In the picture, where they will stay even if you send the picture via email to a friend or show it on your homepage and
2. in a small database of Mapivi. Searching for e.g. "Tom" AND "Tim" in this database will find the picture pretty fast.

Image Management
1. Mapivi supports any existing folder structure
2. Mapivi stores just picture meta information (IPTC, EXIF, comments, ...) in his database
3. Mapivi supports pictures on removable media (CD, DVD, USB-HD, ...)
4. IPTC/IIM information (International Press Telecommunications Council Information Interchange Model) with keywords, categories, location, headline, caption/abstract, writer,
5. EXIF (EXchangeable Image File) information (date, time, aperture, exposure time, ISO speed, ...)
6. JPEG comments (single and multiple comments are supported)

Image Manipulation
1. lossless JPEG rotation (90, 180, 270 degrees or automatic rotation using the EXIF orientation flag)
2. lossless JPEG cropping to any format (useful when printing and framing pictures)
3. rotate pictures at any angle (this is not a lossless operation)
4. resize pictures, change the quality (file size) of pictures
5. filter a picture (normalize, equalize, saturation, gamma, unsharp mask, ...)

Other Features
1. generate and display high quality thumbnails
2. store generated thumbnail pictures in a sub directory (.thumbs) or a central thumbnail database for further access
3. search for pictures (mapivi keeps a database with all file names, directories, EXIF, IPTC data and comments) .
4. import pictures from a digital camera, memory card or other device
5. file operations: rename, copy, move, email and delete pictures
6. directory operations: rename, create, delete
7. compare/diff two picture directories and show all files which differ by: file name, file size, pixel size, comment, EXIF info, IPTC info
8. search for duplicate pictures (by file name or by file size)
9. export a static html web gallery of the selected pictures with comments and EXIF and IPTC infos
10. (mapivi uses a page template so the design and layout of the html page is very flexible). These html galleries may be presented on a web page or burned on a CD-ROM.
11. add a border/drop shadow and/or a copyright info (text or picture) to images
12. build index prints
13. compare details between two or more pictures by switching between these pictures zoomed to the same picture area
14. batch rename pictures (e.g. according to their internal EXIF or file date, e.g. "yyyymmdd-hhmm.jpg")
15. show pictures in a slideshow
16. fix camera CCD defects by interpolating dead and hot pixels (also possible while importing pictures)
17. show the histogram of a picture
18. make screenshots (single window or complete desktop)
19. set a picture as desktop background
