"Slanted Hyphens" are a thing, depending on the font. Going from horizontal/flat (what we all know now), to very tilted up:

Graphic Design (Stack Exchange): "Where and/or why is a slanted hyphen used?"

There's also the "Double Hyphen" which looks like an equals sign:

Fascinating stuff. Still don't know how it works its magic with the PDFs, but it works!

I am just thinking...

How one physical problem and discomfort (having small screen reading device)
led to creation of such great, usefull and productive little piece of software !

Thank you again Mr. Willus for K2PDFOPT!

k2pdfopt better than Word

Willus, Word still messes up equations and mathematical formulas in PDF conversion, using your application is better in case you're looking for math textbooks. Since (I assume) it cuts up the pdf into images, it doesn't mess the formulas.

Thank you for your work, it's magic to me.

Thanks. It certainly depends up on the specific case and what you want out of the conversion. It's always good to have options.

I'd like to add another motion of gratitude to this thread. I tried the Word method to making a particular PDF book readable on my 6" Kobo Clara and it failed terribly. This tool effortlessly did an amazing job!

Noticed a small bug (in 2.53 at least): When adding an EPUB by mistake, the app closes without further ado, instead of just ignoring non-PDFs with a dialog box ("k2pdfopt only handles PDF files.").

compile k2pdfopt

Hi willus,

Thank you for the great tool!
I was trying to compile the k2pdfopt v2.53 in Msys2 MinGW64 but I am very new to CMake and programming in Linux(-like) system. I have installed all the other dependent libs to /mingw64/ and, also compiled mupdf and installed it to /usr/local/include/mupdf for *.h files and /usr/local/lib since there seems no directly available mupdf package. when I was using vscode it told me that
----------------------------------
Code:
[cmake] -- Checking for module 'mupdf'
[cmake] --   Package 'mupdf', required by 'virtual:world', not found
----------------------------------
and then if I right-click on 'CMakeLists.txt' and select 'build all projects', vs code will give me quite a few errors, such like:
--------------
Code:
[build] C:/k2pdfopt_v2.53/k2pdfoptlib/k2ocr.c:760:13: error: static declaration of 'k2ocr_ocrwords_get_from_ocrlayer' follows non-static declaration
[build] C:/k2pdfopt_v2.53/k2pdfoptlib/k2ocr.c:607:9: note: previous implicit declaration of 'k2ocr_ocrwords_get_from_ocrlayer' was here
------------------------------------------
Do you have any suggestions on what I shall do?
instead--I know it's a greedy wish--but is it possible you could add more instructions into your readme_k2src.txt file for new people, if possible? I think this will be even greater.

Thanks a lot!

Hi--sorry for the delay in responding. I'm just curious, why are you trying to compile k2pdfopt in MSYS2? Why not just build it in Windows using a MinGW gcc compiler per my source code instructions. Don't Windows binaries run okay in MSYS2?

I've just discovered this tool, and it looks like it might be useful for converting RPG PDFs for use on my ereaders.

I have a request, though. Would it be possible to add an option to output just text, rather than images with text?

I hadn't, but I have now That, and -mode 2col are ideal for what I want. Thank you.

I'll RTFM next time
