Versie historie van K2pdfopt (64-bit)
<<Terug naar software beschrijving
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.
- **
