great. good job!

Does this Software work only for pictures? Because when I read your description I got the idea that I could scan books and your software could convert it automatically to the ePUB format (that would be so awesome... I have some old books that I would like to share on the Internet).

Hello Emindead,

Yes, you can use it for that purpose.
You have to scan your book, either one page at a time, or two pages at once.
Then you copy all your jpeg files in the "images" directory and launch the program. You answer the questions, and voilà !
Your pictures will be auto cut, cropped, resampled... to make the best ebook (LRF or EPUB) possible.

Just try it and tell me how you find it !

I can't seem to make it work. I scanned a page of a book. Run the program. Answered the questions and the program gets stuck with the same "Screen Size" lines ad-infinitum. What's going on?

tetra · 03-01-2011, 09:00 AM

That's very strenge. I don't have this problem.
You have to answer this question with either 1 or 2.
Could you post me a screen capture of the problem?
Thanks

hi

Idle question : is the source code available?
I've done this similiar thing with 'sam2p' instead of ImageMagicks
'convert' from jpg to pdf .. and found very much reduced file size

Hi ab7vf,
No, the source code is not yet released. I'll think about it ;-)
I have no much time to improve it, so a release one day under GPL may be a good idea.
What would you like the source code for?

The pictures are converted to PNG, hence the file size a bit bigger than JPG. PNG files are better for readibility as there is no artefacts around letters.
Pictures are 16 greyscales. We can split filesize nearly in half using 8 greyscale.

hi tetra

re source .. just to 'play' with .. try sam2p and stare/compare as to source size - converted file size/quality, etc

is it possible that only jpg files are detected?
i got several mangas in png format.

cheers.

I think that this sw makes jpgs in 16 grey colour. Epubs made with calibre are more rich. Is possible use a 256 grey conversion? I like of this sw the crop funcion. Is it made by imagemagik? What is the command line to make a strong cropping? thanks.

tetra · 12-03-2011, 01:47 PM

Hi Sage79,
Cropping is done by my own program. ImageMagick is only used to resize and decrease color depth, and yes, I convert to 16 greyscale.
I'll release the source code as some people requested, so you will be able to continue increasing functionalities, as I have no more time to work on this.

tetra · 12-03-2011, 02:14 PM

I just released source code.
You can download it from my website : http://scantoebook.vassaux.net
I hope you'll enjoy it ! (althow it is a bit quickly written)
Please let me know if you modify the program.
