Thanks kovidgoyal, I'll take a look. I'm finding the library stuff and the cross-platform stuff the hardest thing to work out with Python, the language itself is quite excellent though!

kovidgoyal · 06-18-2008, 10:49 AM

Yeah cross platform is a pain. You may also want to look at the Python Imaging Library. It should allow you to do the transforms easily in python, without relying on an external imaging library. If you need any help with the cross platform stuff, just ask, I have a good deal of experience with it.

I would have liked to use the Python Imaging Library but it misses a few vital functions that ImageMagick provides. Thanks for the pointers on the ImageMagick libraries, there's no mature interface for Python but I've managed to coble together a suitable interface, that now works well, from various sources. Also the ImageMagick documentation is almost non-existent when using the API.
I'll PM you if I have any questions, I'm particularly interested in cracking OS X support next.

I second the OSX support - if you need a guinea pig, just let me know!

this program is very nice. I was unsure of the capability of the prs505 to display comics but after putting a moon knight book on it and reading through it, I'm very impressed. Good work.

Well, I can confirm that the 64mb limitation is completely false.

Using the new pythin version of comiclrf, I have been able to generate a 4615 page, 251,386 kb .lrf file that works perfectly on my prs-505.

It's an archive of Dilbert comics, 1990 to 2005, incidentally.

Update: Version 2.1 released

Python version now works on Mac OS X and Linux.
Now uses built in ImageMagick library and does not use external installation (except Linux)
ImageMagick processing now thread based instead of external process, slightly faster.
Added output directory (-o) option where LRFs are written to.

If you installed previous versions you can uninstall ImageMagick as the latest version has the libraries built-in (except for Linux).

On linux the most robust way to load the magickwand library would be

Code:

ctypes.cdll.LoadLibrary(ctypes.util.find_library('MagickWand'))

FangornUK · 07-02-2008, 10:03 AM

Thanks for the info kovidgoyal. Unfortunately they changed the library naming from Wand to MagickWand etc recently so my version tries to access either.

kovidgoyal · 07-02-2008, 10:11 AM

Well, in that case

Code:

lib = ctypes.util.find_library('MagickWand')
if not lib: lib = ctypes.util.find_library('Wand')

Hi, i was so happy to know u finally compiled your program in osx (i red great comments on your software).
But i uncompressed it and it doesnt work... i just said
>ERROR: Can't load ImageMagick Library /Applications/Multimedia/ebook/comiclrf/ImageMagickOSX/lib/libWand.dylib

i tried to run the program from outside the folder and inside the directory and subdirectories... but still doesnt work...

i want to try it!

FangornUK · 07-03-2008, 07:45 AM

Did you extract everything out of the TAR and all subdirectories? Also is X11 installed? Think ImageMagick might need that but I'm not sure.

Can you see the file "/Applications/Multimedia/ebook/comiclrf/ImageMagickOSX/lib/libWand.dylib"

SurgE · 07-03-2008, 10:57 AM

here's an error:

Extracting...

Traceback (most recent call last):
File "comiclrf.py", line 363, in <module>
File "comiclrf.py", line 298, in runcomic

IOError: [Errno 2] No such file or directory: 'c:\\users\\user\\appdata\\loc

------------------------

I am using the latest version on windows vista. The application died when the cbz file itself has a folder structure inside.
