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Remove outdated FIXME-s for bugs that have been already fixed.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
* Simple implementation of lanczos scaling
* Simple implementation of lanczos scaling
* Refactor lanczos into separate header
This commit moves the algorithm
into its own header. It also provides
templated interface now, utilizing
a little bit of decltype and declval
to resolve types for lambdas and stuff
* Zero pixel at start of lanczos_at
This commit fixes a possible bug and
fixes some style incosistencies
* Improve documentation for Lanczos
This commit adds documentation which
describes when to use the algorithm,
a brief description of how it is
supposed to work, and some caution
on the quality of the output
* Address style issues and fix warnings
This commit fixes a style issue realted
to namespace declaration and
fixes a warning in added zeroing of
a pixel at start of lanczos
* text-realign function arguments
* fix formatting issues
* Implement handful of sanity tests
This commit introduces a couple of
sanity tests such as black image
scaling to black image, and lanczos
response being 0 at x = 0
* bracket on newline for for loops
* add lanczos scaling to tests
* more precision in lanczos calculation
This commit migrates integral values
to double precision and uses PI
provided by boost.Math. These changes
solve downscaled image being darker

* Add Jamfile for ip test directory
Add Jamfile for image_processing
test directory and build-project
from outer test directory
* Add IP test directory to ci build
This commit adds a line at the end
of .ci/build-and-test.sh to include
image processing tests in CI builds
* Remove redundant lines from Jamfile
Simplify Jamfile at
test/image_processing
* Rewrite range condition
x > -a && x < a exchange with
-a < x && x < a in lanczos
* Add newline at the end of files
* Add math and lexical_cast to get-boost
As math and lexical_cast are used
in lanczos scaling, both were added
to get-boost
* Revert "Add newline at the end of files"
Since Boost.Math.Constants is
overengineered for use case by
requiring Boost.lexical_cast or
a global define, it is removed
This reverts commit 0743ab072ff3455421853697f7f46aee7d22382c.
* Define pi and use in lanczos
Value of pi is moved out into detail
and used by lanczos
* Move image_processing to test/core
* formatting fixes
* Adjust CMakeLists for moved IP tests
This commit removes image_processing as
subdirectory from test/ and adds to
test/core's CMakeLists
* Remove unused from get-boost
Since lanczos scaling no longer uses
boost.math.constants, lexical_cast
has been removed as well
* Downgrade math to transitive dep
This is a stray change left from
my incorrect resetting of the HEAD
on lanczos branch
* Remove unnecessary includes
io includes are not used in lanczos
scaling test, and they break build
* Fix ambiguous overload issue for min
Since width() and height() now return
std::ptrdiff_t, call to std::min needs
a cast. There was also shadowing of
pi declared in detail/math.hpp,
which is also fixed
* Apply mloskot's patch
The patch provided by Mateusz changes
all usages of long int into ptrdiff_t,
which is returned by width() and
height() functions of image_view
* Apply .editorconfig rules
This commit is a simple reformat of
affected files
* Use aliases x_coord_t and y_coord_t
The change converges integer handling
in arguments, using view' type aliases.
View arguments have to come first to
avoid non-deduced context problem.
Also replaced long int with ptrdiff_t
in lanczos, in numeric.hpp file
* Apply alias usage for rest of the code
Some places with ptrdiff_t were
left out from previous commit, so they
are changed in this one. Plus a fix for
max call being ambiguous.
* Replace all literals with casted vars
This commit takes extreme stance of
never using an integer literal due to
problems in ambiguity of deduction of
min and max functions
* Fix unenclosed foreach
During rebase of gsoc2019 onto develop,
I didn't enclose first foreach with
matching endforeach, hence tests failed
