Improve utilities sending channels, pixels and other GIL objects to
output stream for logging of test errors.
Fix missing namespace qualification in IO tests.
Comment TARGA test case with FIXME that was accidentally
uncommented in cc64bdd1a4
Motivation is to:
- use on simpler and light test framework,
- eliminate dependency on libraries like Boost.MPL,
- achieve faster compilation times for CI builds (20% seems feasible)
- have test programs easy to run and debug
- avoid macros
Remove outdated FIXME-s for bugs that have been already fixed.
Fix off-by-one bug in test/core/test_fixture.hpp generators.
Minor corrections and tidying up.
Add missing test assertions to numeric extension tests.
Fixes#458
Since `std::uninitialized_fill` performs a placement new on each
element in the range, it is important to ensure core and packed
pixel types behave correctly.
Split general purpose test fixtures into core/test_fixture.hpp.
Refactoring to unify use of the common framework across GIL tests.
Merge `unit_test_utility.hpp` into `unit_test.hpp` for convenience.
Add several test cases to `gil::point` tests.
* Hide convolve_1d and convolve_2d in namespace detail
* Hide kernel_2d in namespace detail.
* Tidy up naming of horizontal/vertical to y/x for kernel center.
Following @lpranam comments on planned changes to convolve_2d,
which will not be ready for Boost 1.72,
@mloskot proposed to hide the function as implementation detail,
https://lists.boost.org/boost-gil/2019/10/0316.php,
until it is ready and @stefanseefeld agreed on the proposal,
https://lists.boost.org/boost-gil/2019/10/0320.php.
Add static assertions to verify channel types are convertible to
expected result type.
Add new and update existing Doxygen comments describing interfaces in
`extension/numeric/channel_numeric_operations.hpp`.
Align with `subsampled_view` overloads accepting `point_t` and `coord_t`
Both types are based on `std::ptrdiff_t`. Fixes compilation warnings.
Tidy up `subimage_view` and `subsampled_view` with trailing return.
Add tests for `subimage_view` in core and dynamic_image extension.
(First tests for the dynamic_image, hurray! :))
Add explicit cast to double in division operator for point<T> to
fix compilation warnings.
First stab at convolution tests includes cases with the identity kernel.
Move `pixel`-s streaming facility used by Boost.Test (required by
`BOOST_TEST` macro) to the common header for re-use in other tests.
Use of `std::extent` was introduced in PR #200 but it turns out as
not applicable for `std::array` or derived types (e.g. `kernel_1d_fixed`).
This led to obtaining invalid size of `kernel_1d_fixed` and erroneous
results of the rows and columns convolution.
This change replaces `std::extent` with new public constant member
`kernel_1d_fixed::static_size`.
Since `kernel_1d_fixed` is derived from `std::array`, the Alternative
could be to use `std::tuple_size` specialization for `std::array`.
Add static assertion to require that kernel size must be odd to
ensure validity at the center.
Split header tests accordingly i.e. test core headers as part of
core tests, numeric extension headers as part of numeric tests, etc.
It extends the convention of sub-directories already established in
`include/boost/gil` directory. It is sensible to follow it in other
areas of the source tree (i.e. `test/`, `doc/` and `benchmark/`).
Another important reason to move the tests is to enable removal of
the top-level `Jamfile` with all its definitions of test-specific
requirements.
The top-level `Jamfile` is not advised, especially if it specifies
build requirements like C++ language version.
Those affect non-tests builds e.g. documentation, causing failures
during generation of HTML documentation (leads to missing docs).
