kovidgoyal has kindly added ComicLRF to Calibre (
original thread). It is now called 'comic2lrf' on the command line or simply the 'Comic' converter in the GUI. It works the same was as converting any other Book in the Calibre GUI but has different option settings.
It converts Comic Books & Manga (CBZ & CBR format) into an LRF file you can load onto the Sony Reader. See
Wikipedia. The CBZ/CBR files are just RAR or ZIP archives of images of comics, so you could easily create your own "Comic Book" of photos.
This program converts the Comic file into a LRF for the Sony Reader. During the processing it resizes the image to fit the Reader's resolution, crops white space around the edges and converts them to 64 "color" grayscale to look their best on the Reader's grey screen whilst reducing the file size. Landscape images are automatically split into two pages. The images are also sharpened slightly to improve legibility of text and "normalised" to improve contrast. The processing is multi-threaded so it makes use of multi-core processors.
