comiclrf - Comics(CBZ) to LRF converter

I have a US model, firmware 1.1.00.18040 with the same issue, the firmware AFAIK is the latest version available from the Sony site.

For now I've resigned myself to convert my comics to LRF as they turn out just fine that way.

I found ticket number #3202 which seems to describe this problem and I tested the epub supplied by kovidgoyal. (riki-oh.2.epub)

What I saw was the following:

Cover page was sharp
1st page was text
2nd page did not display at all <-- comic page
3rd page was sharp <-- comic page

So, it can be made to work. Somehow

Addendum: I just tried Adobe Digital Editions 1.7.1.1085 on WinXP and my comics display badly in that too. This might help with tracking down the bug.

Also, this might be related to the bug that had jpegs not displaying correctly. It would be nice if fixing this allowed jpeg pages too

[Kirtai]

I have finally tracked this down. The problem is that some Sony readers and ADE version 1.7.1.1085 do not like 64 colour (4 bit) PNG images. If you do the conversion with 256 colours it works perfectly.

A bit of experimentation shows that both greyscale and colour JPEGs display correctly too.

I have added this as ticket #3529

Great find. After testing I can confirm that 64 color epubs look pixelated and 256 color epubs look just fine (on my reader, anyway). I've now set 256 colors as the default in the preferences.

Thanks!

[dreamers]

thanks for that find Kirtai. the 256 colour epubs look great. and finally a TOC.

[Kirtai]

I'm glad to hear it fixed your problems too

I haven't read through the whole thread, so sorry if this has already been addressed. ComicLRF is a great utility, but I note in Task Manager that it uses 2 full cores, and nothing more. Since it can use 2 cores, any chance of a future update allowing it to utilize 4?

[kovidgoyal]

It uses 16 cores on my machine.

I was wondering, perhaps ardeegee is still using the original comiclrf script instead of the current Calibre-integrated version.

ardeegee, comiclrf was merged with Calibre a while ago. Are you using the standalone version still?

Yes, I've been using the stand-alone command prompt version-- opening a command prompt on a folder and typing comiclrf *.cb*. I don't see that a shell could be easier than that.

edit to add:

Just tried the Calibre solution-- it did use all my cores. At the expense of several more steps to have to go through than a short command line, plus the Calibre version failed to convert half of the 8 files I picked for a test while the command line version had no problem with any of them. I'd much rather live with using only 2 cores than bother with the shell.

OK, now try Calibre on the commandline

You can stick all your favorite settings in a batch script and get the ease of conversion coupled with using all your cores. Win-win.

not sure if I am doing this right but I am trying to convert a cbr comic to lrf using calibre and I keep getting this error

[kovidgoyal]

Are you sure your cbr file is a RAR archive? Can you open it it with winrar?

[Katep]

yea its a white box with a rar image on it and it opens in rar
