- This archive contains the third version of the database of net.people
- pictures. This version contains 4372 pictures in a format acceptable
- both to NewsGrazer and Mail.app. The pictures fall into three
- categories:
-
- 1. Pictures converted from the faces database on ftp.uu.net. All of
- these pictures are of pretty high quality as they were converted from
- mostly 108x128 pixel 8 bit grayscale images. To preserve aspect ratio
- these images had to be converted to 48x64 pixel images which leaves a
- small blank strip on one side of the image in programs which expect
- the standard 64x64 pixel images. 3419 images fall into this category.
-
- 2. Pictures converted from the faces database on iuvax.cs.indiana.edu.
- Originally these images were 48x48 pixel b/w, so their converted
- versions are of fairly low quality. Still, in most cases they should
- help you recognize the person in question. 909 images fall into this
- category.
-
- 3. Pictures created for the NeXT. These images are generally of the
- highest quality. Unfortunately there are only 44 of them.
-
- Installation:
-
- Before installation make certain that there is enough disk space on
- your disk. The complete database requires almost 5 MBytes and consists
- out of about 4400 files all in one single directory. Creating,
- moving, removing or even listing that many files can take some
- patience even with a fast hard disk.
-
- After unpacking the archive move the complete created People directory
- to /LocalLibrary/Images. If you already have a tiff database in that
- directory move the files from that database to the new People
- directory then move the new People directory to /LocalLibrary/Images.
-
- Making the database available to NewsGrazer only requires a symbolic
- link from /LocalLibrary/NewsGrazer/People to /LocalLibrary/Images/People.
-
- Mail.app needs two additional files in /LocalLibrary/Images/People to
- be able to use the database. These are /LocalLibrary/Images/People/passwd
- and /LocalLibrary/Images/People/aliases. Both of these files have been
- pre-created in the archive and unless you add new tiffs to the
- database you should not have to worry about either of them. If you do
- add new tiffs to the database, just re-run the mkpassalia script in
- the People directory. It will automagically update both files.
-
- Changes from the v1 to the v2 of the database:
-
- 1. About 800 new low resolution tiffs were added to the database
-
- 2. All of the low resolution tiffs ( 48x48 pixels, 1 bit b/w) were
- converted to 64x64 pixel 2 bit gray scale tiffs. That slightly
- improves the impression the images give and removes that ugly border
- around the images when they are displayed in Mail.app or NewsGrazer.
-
- 3. About additional 1400 images were converted from the high
- resolution faces on ftp.uu.net. The resulting images are of much
- higher quality than those previously included from the faces database
- on iuvax. They are however 48x64 pixel tiffs, so if you display one
- of them in Mail.app or NewsGrazer you will get a margin at the right
- hand side of the image. These images largely replaced lower quality
- images which were in the database previously.
-
- 4. Despite the growth in the size of the archive, the disk space used
- for the installed images has not increased by much. Virtually all the
- pictures are smaller than 1 kByte which means that they will use up
- one block of disk space. The difference is that the old low resolution
- tiffs only used about 450 bytes of the block which was allocated to
- them while the new higher resolution tiffs actually utilize about 900
- to 1000 bytes of their kByte. There are about 800 new tiffs, so the
- used disk space will increase by about 800 blocks.
-
- Changes from the v2 to the v3 of the database:
-
- 1. This is basically a "bug fix" version. During the compilation of
- the second version about two thousand high resolution images got lost
- somewhere and so many of the low quality images did not get replaced
- as they ought to have been. This went unnoticed until the moderator of
- the purdue archives pointed out to me that some images had not been
- updated (Thanks, Allen !). This has been fixed and now there are
- mercifully only few of the low quality images left.
-
- 2. A small number of images were added.
-
- 3. There were about 50 duplicate images in the last version. They have
- been replaced by hard links.
-
- Plans for the future:
-
- 1. Future versions of the database will at least also be available as
- incremental changes to this version of the database.
-
- 2. Due to frequent request: I will hopefully finally get around to
- digitize an image of myself and put it in the database, too. :-)
-
- Disclaimer:
- I did not create these images. I did not originally compile most of
- this database. It was converted from several original databases using
- a few shell scripts which converted the files to names acceptable to
- NewsGrazer/Mail.app. I've not looked at all the converted images,
- although a random check of a few dozen of them has not revealed any
- errors.
-
- Thanks:
- Thanks to Steve Kinzler for helping me locate all the pictures for
- this database. Thanks to Jef Poskanzer for writing and making freely
- available the set of image conversion utilities which made this
- database possible.
