Conversion of comics (CBR/CBZ) - Page 2

kovidgoyal · 02-15-2009, 08:49 PM

the windows version of calibre has a built in rar library. Try the following from the command line

any2epub filename.rar

and post the error message

Error I get is:

Code:

Traceback (most recent call last):
  File "from_any.py", line 204, in <module>
  File "from_any.py", line 200, in main
  File "from_any.py", line 170, in any2epub
ValueError: Conversion from CBR is not supported

kovidgoyal · 02-17-2009, 12:39 PM

Oops, my mistake the command should be

comic2epub not any2epub

giddion · 02-17-2009, 02:01 PM

That command gives:

Code:

Traceback (most recent call last):
  File "from_comic.py", line 16, in <module>
  File "C:\Program Files (x86)\calibre\library.zip\calibre\ebooks\lrf\comic\conv

ert_from.py", line 57, in extract_comic
  File "calibre\__init__.pyo", line 144, in extract
Exception: Unknown archive type

But the comic archive opens just fine with comical.

rename the file from .rar to .cbr

giddion · 02-17-2009, 02:52 PM

Did you mean that the other way around? The file is a CBR

When I try to use comic2pdf I get the following error:

Code:

Traceback (most recent call last):
  File "from_comic.py", line 16, in <module>
  File "C:\Program Files\calibre\library.zip\calibre\ebooks\lrf\comic\convert_from.py", line 554, in main
  File "C:\Program Files\calibre\library.zip\calibre\ebooks\lrf\comic\convert_from.py", line 523, in do_convert
  File "C:\Program Files\calibre\library.zip\calibre\ebooks\lrf\comic\convert_from.py", line 395, in create_pdf
ImportError: No module named reportlab.pdfgen

I am trying comic2pdf rather than comic2epub because the graphics output on the epub files is very poor.

comic2lrf works, but I want to try using comic2pdf because I am hoping that the PDF will be able to store graphics scaled so that the image width is saved at the resolution of the Sony's height, so that comics will still be rendered at max resolution when turned to widescreen mode instead of upsampled by the reader. I currently haven't been able to do this with comic2lrf--when the reader scales up an image for widescreen view it is obviously scaled instead of at a higher native resolution, even with the -w flag set.

comic2pdf is not fully functional in the 0.4.x series. It will only be fully integrated in the 0.5.x series.

Please, add an option to enable/disable trimming images of the cbr/cbz. Sometimes trimming doesn't work well, and crops large areas of covers and indexes.

Thanks for all and Greetings from Spain.

open a ticket or I will forget.

I know someone asked this before in the old thread, and I know there are a lot of ways to easily change the extension. But could you make an option so that Calibre recognize zip/rar as comic instead of some kind of text archive? All of my comic files (manga, actually) are in either zip or rar, and changing the extension, while easy enough, is kind of annoying. I don't know how many people depends on the fact that zip/rar is an archive of text files, so I don't ask to change the default behavior, but can I ask for an option? Thank you.

igorsk · 03-19-2009, 06:58 AM

To change extensions of many files, start command promt, change to the directory and type:

Code:

ren *.zip *.cbz
ren *.rar *.cbr

Hypernova · 03-19-2009, 03:12 PM

Thank you igorsk. I really appreciate your help, but I would like to keep my request. I can't claim something like "a lot of people will find this useful", but I still think it's a good thing to have this option.

kovidgoyal · 03-19-2009, 03:58 PM

Making it an option is certainly possible, open a ticket and I'll get around to implementing it at some point.
