jpgtn 2.06
 
Jpgtn is a thumbnailer for JPEG images. 

Jpgtn is based on "tnpic" by Russell Marks and on "gtnpic" by Willie
Daniel. "tnpic" was originally distributed as a utility with Marks' "zgv"
program. "gtnpic" was an attempt to clean up and expand upon the original 
tnpic program and "maybe add some new features along the way." Jpgtn 
differs from both tnpic and gtnpic in purpose. It is not an indexer.

Jpgtn only thumbnails JPEG images. I have no plans to change it to accept 
other input formats. On and off I've thought about adding support for PNG 
output but I haven't had a real need for it myself so I haven't done it. 

Jpgtn can output thumbnails to files with names based on the names of the 
input files, or it can dump to stdout. The stdout support can be a useful
feature for CGI applications.

Jpgtn is based in part on the work of the Independent JPEG Group.


Usage:

jpgtn -d dh1:jpg/tn -q 95 -s 320 dh1:jpg/*.jpg

jpgtn will convert all full size JPEG files from "dh1:jpg" to "dh1:jpg/tn"
directory with width 320 pixels (for 4:3 aspect ration photos - 320x240
resolution) and jpeg quality 95%.

more info: jpgtn -h

jpgtn requires a lot of memory to convert photos out of camera (for 5mpixels
photos 32MB RAM should be enough). If there is not enough memory you will see
"read_JPEG_file: Error" message.
