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

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


Branch: CURRENT, Version: 1.75.3, Package name: leptonica-1.75.3, 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.

leptonica: updated to 1.75.1

1.75.1:
* Simpler and more accurate function for finding word masks from
* text image; better debugging and more thorough testing.
* Added to regression test set: prog/italic_reg
* Fix for potential injection attack using gplot rootdir.
* Bug fix for bmp reading to set opacity.

leptonica: updated to 1.75.0

This is a new version, for major Ubuntu release 18.04.
$TMPDIR path rewriting turned off on Unix; only used for Windows.
Added pix conversion to depth 2 and 4.  We now have general
  converters to 1, 2, 4, 8, 16 and 32 bpp.
Modified giflib to use read/write from/to memory; no temp files;
  no longer support versions before 5.1.
Move most low-level code from separate files to their callers;
  about 30 of them became static.
Improved table detection on scanned page images (tests: pageseg_reg.c)
Added support for write/compare regression tests for files.
Modified printimage for more flexibility.
Enable lookup by key on comma-separated key/value text file.
Update README.html for building with Visual Studio.
Improved functions for getting pixel averages in RGB images
Simplified and speedup of unsharp masking.
New function for detecting and correcting text orientation.
Remove slow sharpening operation when not appropriate during scaling.
Better handling of gplots with 0 or 1 data point.
Coverity scan fixes.
Modified jpeg2000 header to use openjpeg 2.3.
Improved depth accessors for pixa and pixaa; added size accessors
  for pixa and pixaa.
Bug fix in webp interface on read error.
New function that finds the closest boxes in a boxa to any particular
  box, in each of 4 directions.
New regression tests in automated sequence: blend5_reg, quadtree_reg,
wordboxes_reg.
New program: textorient
Removed programs: snapcolortest

1.74.4  11 Jun 17
- Converted two progs to reg tests
- New version because 1.74.3 had some spurious files (xtractprotos,
  endianness.h)

1.74.3  9 Jun 17
- Coverity scan fixes.
- Several fixes for running on Windows, including subtle one with tiff
  encoding depending on pad bits.
- Utility and test if a page image likely has a table.
- Remove use of pixCreateTemplateNoInit() where it may cause problems.
- Make release 'configure-make ready'
