ComicLRF has now been added to kovidgoyal's Calibre
. It uses Calibre's GUI as well as a command line utility (comic2lrf). I'll keep this here for now until the code has matured in Calibre.
Command line program to convert Comic Books (CBZ & CBR format) into an LRF file you can load onto the Sony Reader. See Wikipedia
This program extracts and converts the images using ImageMagick into a format suitable for the Reader. The images are resized to match the Reader screen size, white spaces around the edges of the images are cropped and the images are converted to 64 "color" greyscale to look their best on the Reader's grey screen whilst reducing the file size. The images are also sharpened slightly to improve legibility of text.
Install instructions are in the README.txt in the download files.
How to use
Once installed open a command/terminal window in the directory with your Comics, then simply pass it the path of the CBZ/CBR file, e.g.
comiclrf "Simpsons 01.cbz"
(You can pass multiple files to it and use wildcards)

Some samples; first one fills screen, second preserves aspect ratio
