tests. There are now 95 tests in the regression set.

Version 1.74.0 10 Dec 16

* Leptonica development was moved to github. The master is at:
github.com/danbloomberg/leptonica

* New modes for RGB --> gray conversion.

* New functions added for displaying a pix from a pixa.

* Split out sort/hash/set/map functions for dna, sarray and pta.

* More robust horizontal deskew on multi-column page images.

* Improve webpio_reg test.

* Remove X11 display for gplot; it is no longer supported.

* Remove most sleep calls, which were put in for gplot; no longer needed.

* Removed use of gthumb in library.

* Removed use of pixDisplayWrite() in the library; still in some progs.

* Improved test for endianness in makefile.static; no longer requires
any local files or building and running a program.

* Modified all files for doxygen output (spearheaded by Jurgen Buchmuller)

* Add read/write serialization functions from/to memory for all
the major data structures that do not already have them.

* More serialized boot recognizers stored as self-generating code.

* Cleaned up generating an adapted recognizer from the boot recognizer.

* Simplified temp file naming; removed most instances of named
temp files from non-debug code; use tmpfile() and a wrapper
l_makeTempFilename().

* Simplify and streamline multipage tiff reading (Jeff Breidenbach).

* Improvement of Otsu thresholding.

* Recognize outstanding contributors to leptonica over the years.

* New gif mem read/write interface that avoids writing a temp file,

* Final mods for compatibility with tesseract 4.00.

Tue Feb 2 13:00:00 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 14:00:00 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 14:00:00 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 13:00:00 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.

margins; works at book level; is more robust to bad disparity
models; version 2 serialization.
