* Version: 0.8

* overall: Reorganize program in a more modular way.

* pi.image: Add unpaper support for scanned book

* pi.image: Add column compress support for scanned book

* pi.divide: Add simple divider for divide = 1

Following the discussions in https://www.mobileread.com/forums/showthread.php?t=30261, I cam to this thread.

I really appreciate the idea and effort of you guys. I just have a tiny question. Could you please please please consolidate a package that be easier to use?

I read through the discussion and notices that the program "should" be able to convert a pdf to a lrf according to the described algorithm. However, I just do not have the know how-to to test the program.

Is it possible for some of you experts to develop a binary package/script with a simple interface that can be run by a dummy people like me? I understand that you experts' major interests a in impoving the image processing algorithm. But if the package can be used by simple clicks/command, it will attract more people's interests and suggestions.

Thanks

Hi everyone !
First of all, thanks caritas for your work and for sharing it ! You really had a good idea !

I've managed to run your code from os x 10.5.5, but with lot of hassle and trial. It now works flawlessly!(Still I think that there's some room for optimization!).

If anyone else is interested in running this program on a mac os x box, I'd be glad to share my experience with them !
(Either in this thread, another thread or by PM).

Sam.

How about building a wiki page?

Hi Caritas,
I really like your idea of PDF-reflow. I also developed a program for a similar purpose (rendering multi-column PDFs in small devices - I read lots of two-column papers these days.) I wonder if it is okay to adopt your idea into my program?

It's my pleasure that this program is helpful to you. You can adopt the idea. But if you want to use my source code directly, please open source your source code too.

BTW: Can you give me a link to your program?

Taesoo Kwon · 11-14-2008, 07:10 PM

Thank you. I will. The link is:

Sam,

would be great if you could share how you made it work for Leopard. I've spent all day adapting and fixing and finally got stuck with compiling pi_page_parse - could not find pgm.h file to include.

Would be great if you could outline the steps and dependencies for compiling.

Thanks,

damir

marcusgennaroz · 12-10-2008, 07:20 AM

Sam, please could you give us some documentation on how to run it on Mac OSX?

Thanks!
Marco

Nice algorithm.Many many thanks.

daesdaemar · 12-13-2008, 09:49 AM

OK, I'll be the first to admit I'm a dummy and need some help. Please, I need BASIC instructions on how to run this.

I have extracted the "pi" folder to my C: drive and open a cmd prompt window and cd to the pi directory and then I am stuck and can get nothing else to work.

Note that I am trainable. I asked for this type of basic help for mobidedrm and can now use that script quite nicely. I just need to learn how to get it to run.

Thanks in advance.

EDIT: OK, I think I have figured out that the original script from caritas does not run under Windows. I did download the Windows version by ashkulz, but am still stuck. I do have python 2.6 and PIL installed.

EDIT yet again: here is a pic of the error message I am getting.

daesdaemar · 12-15-2008, 04:24 PM

Bump my post immediately prior to this one. Don't think I ever had a "no-response" for over two days before???

daesdaemar · 12-20-2008, 08:33 AM

Bump again... Does anyone still use this script or follow its discussion?

I guess everyone is away for the holidays... anyway, your problem is that you have PIL installed incorrectly. Either get a 2.6 version of PIL or install Python 2.5.2 and the 2.5 version [the _imaging module is the C code which implements PIL].

Would it be possible to update your pi-0.6 for Win32 to the more recent 0.8 version? I too cannot use this latest version and have never been able to use pi in windows until I used your port.
