The free variants of operator/ and operator* now yield new
type of point<T> with T promoted to type common for both operands.
Add missing member operator*=, for symmetry.
Add template function iround(point<T>) as no-op sink for point
specialisations for T of integer types.
Add explicit casts of arithmetic intermediate results to avoid
compilation warnings.
Replace redundant point<T> construction in return statement with uniform
initialization.
Add static_assert validating range of axis_value integer template parameter.
Update test/point/point.cpp with basic checks of all point<T> members.
Fixes#153
Add point2<T> alias template for backward compatibility with Boost <=1.68.
Replace multiple point_t aliases of point<ptrdiff_t> with single defined
in point.hpp. The point_t is common used to represent dimensions.
Replace many uses of point<ptrdiff_t> with point_t.
Apply reformatting around point2 changes to respect the line length limit.
Follows up discussion in #154
For each header, a translation unit is generated along with
corresponding compile target.
Currently, only boost/gil/*.hpp and boost/gil/io/* headres are included.
On CI services, compile self_contained_headers targets only if
TEST_HEADERS environment variable is set. This is to avoid build
timeouts due to CI services limits.
When running b2 locally, the tests are compiled by default.
Group include directives, sort within group:
* In headers of GIL core and extensions:
1. boost/gil/extension/*
2. boost/gil/*
3. boost/*
4. C++ standard library headers
* In programs:
1. boost/gil/*
2. boost/*
3. C++ standard library headers
4. "xxx.hpp" for local headers
Add basic guidelines to CONTRIBUTING.md.
Add/Remove #include <boost/config.hpp> or std headers un/necessary.
Rename gil_concept.hpp to concepts.hpp.
Remove gil_all.hpp - we already have all-in-one boost/gil.hpp.
Tidy up and unify copyright and license header.
Tidy up formatting and excessive whitespaces in some comments.
Remove Doxygen block with file description, author, date, etc.
Remove dead or commented pragmas and directives.
Trim trailing whitespaces.
The assignment was superfluous in general case and incorrect in specific
case when the algorithm was given a lambda expression.
The copy assignment operator is defined as deleted for lambda
expressions.
Add minimal test for for_each_pixel algorithm to verify it compiles with
lambda expression.
* Applies patch from John Femiani submitted via Trac
https://svn.boost.org/trac10/ticket/2222 description:
It would be convenient if GIL views modeled ReversibleCollection concept.
In fact they almost do already. Without modeling this concept, it is
hard to use an image view with boost::range algorithms.
* Add related image_view concepts for Collection, ForwardCollection,
ReversibleCollection.
* Add tests for the new concepts.
* Add run-time tests for the new image_view methods.
* Apply patch from https://svn.boost.org/trac10/ticket/8896
* Add compile-time test of RandomAccessNDImageViewConcept
* Confirms the reported failure (tested with GCC 7.3 and clang 5.0)
* Verifies correctness of the patch
Add GIL_DISABLE_FINDBOOST_DOWNLAOD option (default=OFF).
Output values of Boost_INCLUDE_DIRS and BOOST_LIBRARY_DIRS
- should help to know which Boost we are building GIL against.
Fix add_executable with empty sources list.
Copied from Boost.Geometry, including original tests, with some non-functional
modifications explained in the comments.
The utility can be used where it is important to avoid integer overflow.
Motivation:
- state clearly what is covered with tests without reading non-trivial code
- avoid cleverness - tests should be no-brainer
- get closer to one test case targets one feature/beaviour with one check
- replace obscure `throw std::exception` with diagnostics that are actually
useful to pin-point failure cause and location - makes CI logs useful.
- allow to select and run specific tests
- make tests maintenance easy, quick and fun
Propose new structure of tests that reflects the previous tests hierarchy,
but organizes channel tests in test/channel directory with test programs
each covering specific library feature (or set of closely related features).
The refactored tests cover 100% of checks from the old `channel.cpp`,
plus it refines or adds a bunch more.
NOTE: old test/channel.cpp has not been removed yet.
Common definitions from the single test/channel.cpp moved to
channel_test_fixtures.hpp and namespace boost::gil::test::fixture:
Classes and typedefs:
- `do_test` as `fixture::channel`
- `value_core` as `fixture::channel_value`
- `reference_core` as `fixture::channel_reference`
- `packed_reference_core` as `fixture::packed_channel_reference`
- `packed_dynamic_reference_core` as `fixture::packed_dynamic_channel_reference`
- `channel_archetype` and relatives to `channel_concepts.cpp` which is compile
test in Jamfile
- `test_packed_channel_reference()` parts as `fixture::packed_channels565`
- `test_packed_dynamic_channel_reference()` parts as `fixture::packed_dynamic_channels565`
Test case functions called from `do_test<T>::test_all`:
- `test_channel_invert()` to `algorithm_channel_invert.cpp` suite
- `test_channel_convert()` to `algorithm_channel_convert.cpp` suite
- `test_channel_multiply()` to `algorithm_channel_multiply.cpp` suite
- `test_channel_math()` split to `algorithm_channel_relation.cpp`
and `algorithm_channel_arithmetic.cpp`
Add test cases for each channel value type T as used to run from
`test_channel_value_impl<T>`, `test_packed_channel_reference<T>` and
`test_packed_dynamic_channel_reference<T>`.
Add list of possible T-s defined as type-lists `fixture::channel_byte_types`,
`fixture::channel_integer_types`, `channel_float_types` and
`channel_bitfield_types` which used with `BOOST_AUTO_TEST_CASE_TEMPLATE`
generate all possible combination of inputs.
Add new `channel_test_fixture.cpp` is a self-test suite verifying the fixtures.
Import the selection of integer types into boost::gil namespace,
and move from channel.hpp to typedefs.hpp for easier access.
Replace bits32f with float32_t and bits64f with float64_t
- kept as alias of scoped_channel_value.
Move float64_t (bits64f) to typedefs.hpp.
Replace the four {float|double}_{zero|one} min/max channel values
with float_point_zero and float_point_one templates.
Replace <boost/cstdint,hpp> with C++11 <cstdint>.
Introduce preference of using declaration instead of typedef.
Reformat typedefs.hpp to take advantage of the using declaration
- works much better for left-to-right reading, alias name as
most important detail comes first.
Add some of missing #include typedefs.hpp, sort some headers.
This enables test runners to copy the file to the target. It also makes
the code that looks for the file in a different path unnecessary since
Boost.Build will pass the proper relative path.
Bump MSVC warning level to W4
Preparing for detailed warnings clean up based on:
https://svn.boost.org/trac10/wiki/Guidelines/WarningsGuidelines
Group compilation flags and defines in common top-level Jamfile
- relies on Boost.Build feature of referring parent Jamfile-s.
Reverts commit SHA-1:e80f9d2f4b2c688b3f7a77b9845e28793e4f5d0b
Preparing to verify if fix for overflowing bit-shift operation (UB)
suggested by Andrey Semashev via Boost ML will fix the checksum bug too.
See discussions for #46 and #50 for details.
First stab at collection of CMakeLists.txt for Boost.GIL
- Allow building and testing boostorg/gil against Boost from
cloned superproject or installed distribution.
Add CMakeSettings.json config file for VS2017 integration with CMake
- Defines build configurations for VS and Ninja generators.
- Can be used as is or as a template ready to customise.
Add conanfile.txt for Conan package manager (eg. for cmake -DGIL_USE_CONAN=ON).
Add .editignore file to with basic encoding of CMake and CI scripts.
Update .appveyor.yml with two extra CMake-based builds (allowed to fail).
