doesn't work with RTL langauges like arabic, it treats the text as english and as a result an arabic sentence is broken in two line but in reverse order which make it unreadable, need to add an RTL option to the app

It's complicated enough to get mixed LTR and RTL texts to display correctly, I don't think it's easy to process it backwards from image to text, but maybe something could be done with the intrinsic directionality of Unicode characters...

The way k2pdfopt works--by immediately converting to bitmaps--I'm afraid auto-detecting mixed text is beyond my current bag of tricks. It would have to involve some form of OCR or some new way of parsing the PDF file. Sorry.

Thanks for the new version, this is definitely the best PDF optimizer out there! I would say the reading experience for 75% of all the PDFs I read on my Kindle (and I read a lot) is vastly improved thanks to this program.
I found a PDF file that crashes the new version 1.25 of k2pdfopt. IIRC, conversion of this file used to work with older releases. The PDF file is here: http://people.csail.mit.edu/dnj/publ...comparison.pdf If I convert this file using v1.25 on Windows XP (win32) , it crashes a couple of pages into the file. If I use the "-gs" option, it completes successfully. Perhaps the new version has an updated PDF library that has a regression? |

It works fine (and thx a lot for it)... only how am I able to append options on Mac? It seems it always interprets them as part of the file path and thus never makes use of them (justification is something I would really like to do)...

1. (Start terminal shell and type in 2 - 5 below) 2. cd Desktop 3. cat > k2pdfopt_custom ./k2pdfopt -ui -j 0 -odpi 250 <Ctrl-D> 4. chmod 755 k2pdfopt_custom 5. exit Now k2pdfopt_custom should behave like k2pdfopt but with the new command line options (which are just an example). Add the -ui so that the interactive menu still comes up. |

Unfortunately i'm getting "format error: not a PDF or corrupted." when trying to open the result after converting with "-odpi 150" or without any option. The source PDF is about 3.6MB and the result varies between 1.5M and 300KB.
The source contains pictures, 2- and 3-columns pages. I'm using the latest version (just downloaded) for Windows running XP SP3. Any idea ? |

Sorry. I'd really need to see the file to track down whatever is happening in XP. I understand if you can't post it, though.

I think there is a win32 version, probably for xp, or maybe an older xp version is available? Cheers, Tom |
