./graphics/leptonica, Software for image processing and image analysis applications

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.85.0, Package name: leptonica-1.85.0, Maintainer: adam

This package contains well-tested C code for some basic image processing
operations, along with a description of the functions and some design methods.
A full set of affine transformations (translation, shear, rotation, scaling)
on images of all depths is included, with the exception that some of the
scaling methods do not work at all depths. There are also implementations of
binary morphology, grayscale morphology, convolution and rank order filters,
and applications such as jbig2 image processing and color quantization.


Required to run:
[graphics/tiff] [graphics/png] [graphics/openjpeg] [graphics/giflib] [graphics/libwebp]

leptonica: updated to 1.84.1

1.84.1
* Remove support for openjpeg versions < 2.1.
* Improve error handling for stringLength() and stringCat(), and
  add tests in prog/string_reg.
* Source files changed: blend.c, dnafunc1.c, jp2kio.c, pageseg.c,
  partify.c, pix1.c, ptafunc2.c, sarray2.c, utils2.c
* Prog files changed: boxa3_reg.c, string_reg.c, writetext_reg.c,
  deskew_it.c

1.84.0
* Add getPdfPageCount() to find the number of pages in a pdf file.
* Add getPdfPageSizes() and getPdfMediaBoxSizes() to find the
  information necessary to render images properly.  Modify cleanpdf.c
  and concatpdf.c to use this information.
* Add prog/splitpdf.c to split a pdf file into nearly equal page sets.
* Add ability to read and write rgba in bmp format, and
  test in ioformats_reg.
* Add regression test prog/partition_reg.c
* Change the autotools library name from liblept to libleptonica,
  to be consistent with the cmake library name.  (Apologies to Jeff!)
* Add tests for 24 bit pix reading and writing in bmp and png in
  ioformats_reg.  Test new pixDisplayDiff() for visualizing diffs.
* Allow prog/concatpdf to output pdf with tiffg4 encoding and with
  mixed tiffg4 and DCT encoding depending on image color content.
* Rename prog/concatpdf --> prog/compresspdf
* Put image processing and generation of output pdf from compresspdf
  and cleanpdf into functions in new files: pdfapp.c, pdfappstub.c.
* Add versatile function for cropping an image and filling to
  page size, along with prog/croppdf to do this on pdf file.
