Veranderingen voor v2.40 - v2.41

  • ENHANCEMENTS
  • - Updated libraries: MuPDF v1.10a, Tesseract 3.05.00,
  • Leptonica 1.74.1, FreeType 2.7.1, libpng v1.6.28, zlib 1.2.11.
  • - Compiled with MinGW/GNU C 6.3 (MS Windows version)
  • NEW FEATURE
  • - Added bitmap erosion filter (-er option) as an alternative to gamma correction (-g) to make text thicker/darker (idea from the original "Yet Another PDF to LRF Converter" program).



Veranderingen voor v2.34b - v2.35

  • ENHANCEMENTS
  • - Mac OSX version compiled on new machine running Sierra with GCC 6.2.0.
  • Also, the binaries are compressed with a newer version of UPX which is compatible with Mac OSX 10.12 Sierra.
  • - Linux binaries compiled on CentOS 7.2 with GCC 4.8.5.
  • - Windows binaries compiled with GCC 6.2.0 (MinGW).
  • - Compiled with the latest versions of libpng (1.6.25), freetype (2.7), turbo JPEG (1.5.1).
  • - I tried newer versions of MuPDF (v1.9a and v1.10 pre-release), but they broke more things than I was comfortable with, so I've stayed with MuPDF v1.8 for this release.
  • NEW FEATURES
  • - Added -jfc- option to prevent trying to join figure captions to the figures.
  • - Added new conversion mode, -mode concat, which keeps the output at the same dimensions as the source file and concatenates crop-boxes (red boxes) together--as many as can fit on each page without breaking them apart.
  • - Added option -f2p -3 to support -mode concat.
  • BUG FIXES
  • - No longer crashes in native PDF output mode if there is no output.
  • - Writes more informative message to screen if output file not written.
  • - Makes sure output file can be opened for writing before proceeding with the conversion. Warns user if file cannot be opened.
  • - Correctly processes blank/empty pages in .djvu files.
  • - The -title option now substitutes the file name for %s or %b, like the -o option.
  • - The -grid overlap percentage is more precise now.
  • - Warning message to use -fc- with -odpi, -fs, or -mag. Not sure this is the best way--should I just turn off -fc if those are specified?
  • - Wide-char (UTF-8) DJVU file names now work.
  • - Blank pages no longer cause an improper conversion with -mode trim.
  • - Clarified usage of -mode copy, explaining about gamma and contrast settings (how they are not reset to 1 with -mode copy).
  • - In the function where the 2-column divider is detected, a special call is made to find_textrows() so that figure caption joining is disabled unless -jfc+ is specified. This helps 2-column detection work more reliably.
  • MS WINDOWS GUI BUG FIXES
  • - The GUI now correctly selects the "crop" conversion mode.



Veranderingen voor v2.32 - v2.33

  • NEW FEATURES
  • ** - Compiled with GCC v5.2.0 and MuPDF v1.7a (released May 7, 2015).
  • ** The MuPDF upgrade involved modifying a significant amount of the
  • ** MuPDF interface code in the willus library since Artifex changed the
  • ** APIs on several functions, but the bulk of the logic did not change.
  • ** I uncovered a bug in the pdf_dict_del() function as well (reported).
  • ** - The -i option displays information about the source PDF file. Added
  • ** to MS Windows GUI also.
  • ** - Added -fr option to rotate wide-aspect-ratio figures to landscape.
  • ** http://www.mobileread.com/forums/showthread.php?p=3060339#post3060339
  • ** - Added Kindle Paperwhite 3 (2015 release) and Pocketbook Basic 2 to
  • ** dev list (from http://www.mobileread.com/forums/showthread.php?t=253579)
  • ** - Smarter sorting of red regions on a multiple-column page. See
  • ** pageregion_sort() function in pageregions.c.
  • ** - New -ibox option has same format as -cbox, but these boxes are ignored
  • ** by k2pdfopt--they are "whited out" in the source file. For native
  • ** output, the contents may still be visible in the output.
  • ** - The -neg option now attempts to only negate text passages to white
  • ** on black and to leave figures alone. Use -neg+ to negate everything.
  • ** http://www.mobileread.com/forums/showthread.php?p=3104536#post3104536
  • ** - Added option -ehl to erase horizontal lines in the document. Works
  • ** exactly like the -evl option.
  • ** - Added -author and -title options to specify the author and title of
  • ** the output PDF.
  • ** http://www.mobileread.com/forums/showthread.php?p=3112052#post3112052
  • ** - Added -px option to exclude a set of pages, e.g. -px 4,7,10-20.
  • ** http://www.mobileread.com/forums/showthread.php?p=3112052#post3112052
  • ** - User can use color markings to tell k2pdfopt where to apply page
  • ** breaks to the output file.
  • ** http://www.mobileread.com/forums/showthread.php?p=3152988#post3152988
  • ** - The -? option can now be followed by a (wildcard) matching string to
  • ** show the usage of a particlar option, e.g. -? -ws.
  • **
  • ** NEW MS WINDOWS GUI FEATURES
  • ** - Crop margins replaced by three crop-box entries.
  • ** These entries can act as either -cbox or -ibox.
  • ** - Added an "INFO" button to show information on the selected PDF file.
  • ** - If a wildcard is specified for a PDF source file
  • ** on the command line (e.g. *.pdf), and the GUI is launched, all matching
  • ** entries are placed into the GUI file list.
  • **
  • ** BUG FIXES
  • ** - With notes options turned on (-nl / -nr), k2pdfopt will still search
  • ** for multiple columns if no notes are found on the page. In addition,
  • ** the -crgh option now more directly affects column divider finding.
  • ** See textrows_remove_small_rows() call in bmpregion_find_multicolumn_divider().
  • ** http://www.mobileread.com/forums/showthread.php?p=3148589#post3148589
  • ** - Fixed multiple file select (broke when I converted to wide chars in v2.30).
  • ** - Modified bmpregion_hyphen_detect() to be less strict about rejecting
  • ** hyphens that aren't exactly centered. Also modified calculation of
  • ** lcheight in bmpregion_calc_bbox()--see the function.
  • ** http://www.mobileread.com/forums/showthread.php?p=3119501#post3119501
  • ** - The k2pdfopt web site and help pages work again from the help menu.
  • ** - Turned off some debugging text from the bmp_autocrop2 function in k2bmp.c.
  • ** - Not really a bug fix, but the command-line help is now shown in
  • ** Courier New in MS Windows (a mono-spaced font).
  • ** - In info_update() in wmupdf.c in the willus library, I check to see
  • ** if I can resolve the Info dictionary. This checks to see if it can
  • ** be parsed correctly. If not, I discard the dictionary. This was
  • ** causing a bug that a user submitted to me in an e-mail on 15 April 2015.
  • ** The users had a PDF file with a corrupt "Info" dictionary.
  • ** - WPDFOUTLINE structures correctly freed.
  • ** - MuPDF v1.7 stores ligatured characters differently than previous versions
  • ** in its internal character arrays, so I had to compensate for this.
  • **
