* Tue Feb 02 2016 lazy.kentAATTopensuse.org- Update to 1.73.
* All lept_
* functions have been rewritten to avoid path rewrites for output to temp files, which were introduced in 1.72.
* Added grayscale histogram functions that can be used to compare images.
* Added functions to determine if an image region has horizontal text lines.
* Added functions to compare photo regions of images to determine if they\'re essentially the same.
* Added red-black tree utility functions to implement maps and sets.
* Improved security of tiff and gif reading, to prevent memory corruption when reading bad data.- Change major library version to 5.- Change programs prefix from \"leptonica\" to \"lept\" (make the names simpler to use).
* Sun Sep 27 2015 asterios.dramisAATTgmail.com- Update to 1.72:
* Better handling of 1 bpp colormap read/write with png so that they are losseless. The colormap is always removed on read and the conversion is to the simplest non-cmapped pix that can fully represent the input -- both with and without alpha.
* Fixed overflow bug in pixCorrelationBinary().
* Fixed orientation flags and handling of 16 bit RGB in tiff.
* Also new wrappers to TIFFClientOpen(), so we no longer go through the file descriptor for memory operations.
* Improvements in the dewarp functions.
* New box sequence smoothings.
* New antialiased painting through mask; previously it was only implemented for connected components in a mask.
* Better error handling and debug output with jpeg2000 read/write.
* Implemented base64 encoding. This allows binary data to be represented as a C string that can be compiled. Used this in bmf utility.
* Implemented automatic code generation for deserialization from compiled strings (stringcode.
*)
* Regression tests write to leptonica subdir of in windows; in unix it is optional. This avoids spamming the directory.
* Added new colorspace conversions (XYZ, LAB).
* New source files: encoding.c, bmfdata.h, stringcode.c, stringcode.h, bootnumgen.c.
* Removed source files: convolvelow.c, graymorphlow.c
* New programs: genfonts_reg, colorize_reg, texturefill_reg, autogentest1, autogentest2.
* alltests_reg now has 66 tests.- Added new build requirement openjpeg2-devel for openSUSE > 13.1.
* Sat Sep 27 2014 lazy.kentAATTopensuse.org- Update to 1.71.
* This version supports tesseract 3.0.4. In particular, 3.0.4 has automatic conversion of a set of scanned images, either in a directory or coming directly from a scanner, into pdf with injected text. This is something we\'ve wanted to do for several years!
* Improved jp2k header reading, including resolution.
* Removed src files: rotateorthlow.c, pdfio.c, pdfiostub.c.
* Renamed jp2kio.c, jp2kiostub.c ==> jp2kheader.c, jp2kheaderstub.c. These header reading functions parse the jp2k files, and don\'t require a jpeg2000 library.
* New jp2kio.c, jp2kiostub.c, that uses openjpeg-2.X to read and write jp2k. We now support I/O from these formats: png, tiff, jpeg, bmp, pnm, webp, gif and jp2k as well as writing to PostScript and pdf.
* New pdfio1.c, pdfio1stub.c, pdfio2.c pdfio2stub.c, where we\'ve split functions into high and low level.
* Fixed memory bug in bilateral.c.
* Improved reading/write of binary data from file. For example, l_binaryReadStream() can now be used to capture data piped in via stdin.
* Font directory now arg passed in everywhere (not hardcoded).
* Don\'t write temporary files to /tmp; only to a small number of subdirectories, to avoid spamming the /tmp directory. E.g., for regression tests, the current output is now to /tmp/regout/.
* For jpeg reading modify pixReadJpeg() to take as a hint a bit flag that allows extraction of only the luminance channel.
* Allow wrapping of pdf objects from png images without transcoding.
* Better support for alpha on read/write with png, including 1 bpp with colormap, alpha (supported in png with transparency array).
* Sun Jan 26 2014 lazy.kentAATTopensuse.org- Update to 1.70.
* New bilateral filtering.
* New simple character recognition utility.
* Improved dewarping functionality, in model building and rendering. More flexible use of ref models.
* Better and more consistent handling of alpha layer in RGBA, though use of the spp field. Ability to handle more png files with alpha, including palette with alpha.
* New fast converters from jpeg and jpeg2000 to pdf, without transcoding.
* Made bmp reader (and pix reading in general) more robust; avoid size overflow errors.
* New text labelling operations; depth conversion of a set of images.- Major version changed to 4.- Rename liblept-devel to leptonica-devel.- Drop liblept-1.69-no_return and leptonica-1.69-giflib5 patches (fixed upstream).- BuildRequires: pkgconfig(libwebp) >= 0.2.0- Correct URL and a source URL.

* Improved sorting efficiency of numas in cases where binning, which is order N, makes sense.
* Fixed fpix serialization (now version 2).
* New version (5) of xtractprotos, allows putting prototypes in-line in allheaders.h. Having them separately in leptprotos.h still an option.
