This should have been done in c2e5749443 (Fix crash when reading
truncated GIF image, 2023-07-02), but was forgotten there -- so do it
now, and add a comment reminding not to forget it the next time.
See #23409.
Add a unit test case checking that we don't crash any longer and still
read the image meta data correctly, even if not the image itself.
Also add another check for EOF and possibly invalid "bits" value in
another place where we were not checking for it when reading from the
stream.
Closes#23409.

This fixes several minor bugs in the loading of `BI_BITFIELDS` bitmaps,
related to handling different header sizes and the colour and alpha
masks.
Closes#23601.
Use Catch2 public header instead of using internal Catch v1 headers: we
can do this now because Catch2 supports (albeit in a rather ugly way)
being used with PCH.
Testing this class doesn't make much sense any more as it's just a
typedef for std::vector and we can presumably rely on the standard class
working as expected.
This makes the code much more clear: LoadDib() now reads all the header
data while LoadBMPData() reads bitmap data only and doesn't read any
header values any more, unlike before.
It also allows not to have to pass neither bmpOffset nor IsBmp
parameters to LoadBMPData(), making its argument list much more
reasonable.
Finally, and, most importantly, it fixes loading bitmaps using
BI_BITFIELDS that was broken back in cccda9ef6b (Fix loading colour
palette from BMP file, 2019-12-28).
This commit also adds a unit test checking that this doesn't get broken
again without anyone noticing.
See #18634.
Closes#22499.
No real changes, just use a more clear and longer (which will be
important for the next commit) name for a test file.
Remove the non-existing samples/console/testdata.gc from make_dist.mk
(there are other non-existing files still referenced there).
This file was listed in test.bkl but wasn't actually copied because the
value of <files> was overwritten by another <files> just below ever
since the changes of 21fe35aff7 (add wxImage test units to test loading
from both seekable and non-seekable streams, 2009-06-01).
Fix this by splitting this wx-data into 2 different ones, to avoid this
conflict.
- Fix handling of delta encoding that change vertical position
- Fix handling of end-of-line encodings that are given mid-line
- Removed unnecessary computation for linepos
Add regression tests for the bitmaps using RLE and loading which
previously didn't work correctly.
Closes https://github.com/wxWidgets/wxWidgets/pull/2590Closes#19318.
Stop throwing std::bad_alloc when BMP has large/negative biClrUsed by
checking that biClrUsed has a reasonable value before attempting to
allocate however much memory it indicates.
Add unit tests showing the loading such invalid bitmaps now correctly
returns an error rather than throwing an exception.
Closes https://github.com/wxWidgets/wxWidgets/pull/2583Closes#19295.
Add more functions for manipulating wxImage colours.
Show using them in the same and add new unit tests for them.
This is a squashed commit of branch 'tomay3000/image-lightness'.
Closes https://github.com/wxWidgets/wxWidgets/pull/2310
We need to explicitly link with the system libraries required in this
case, as static wxwebview library doesn't pull them in (it's also better
to link with them explicitly even when using shared libraries, but in
this case linking at least still worked due to transitive dependencies).
Add new image test files added in 6e8da8641c (Add alpha blending for
wxImage::Paste, 2020-09-23) and 1f0ade29f0 (Fix using mask colour even
if there is no mask in wxImage::Paste, 2020-09-30) to Makefile, so that
they're copied to the build directory and could be found by the test
there, otherwise running wxImage::Paste test when building outside of
the source directory failed.
Check that all our public headers compile with this macro defined and
that using a char string without specifying its expected encoding
results in the expected compilation failure in this case.
This variable doesn't exist any more, but now it's possible to use
CPPFLAGS directly and get rid of the hack which required it to be used
in the first place.
This doesn't work anyhow, so it's better to prevent the code doing this
from compiling instead of getting run-time asserts or worse.
Also simplify construction of these events inside wxWidgets by passing
the window itself to the ctor instead of passing just its ID and calling
SetEventObject() separately later.
For consistency, do the same thing for wxNcPaintEvent too.
With wxSTC, popup autocompletion lists and call tips need to be able to
show their information and respond to mouse clicks, but should never
take focus from their parent STC. This test verifies that these popups
function in this manner.
No real changes, just clean up sources by removing trailing spaces from
all the non-generated files.
This should hopefully avoid future commits mixing significant changes
with insignificant whitespace ones.
Compute the best size of the notebook, taking into account all the
different layout possibilities, and add a test checking that this works
as expected.
Closes https://github.com/wxWidgets/wxWidgets/pull/1085
This basically removes the "adv" library, even though it's still
preserved for compatibility with user make/project files referring to
it.
It is done because the distinction between "adv" and "core" was never
really clear (e.g. why wxTreeCtrl was in core but wxTreeListCtrl in
adv?) and it prevented some core classes from using adv ones.
It seems better to organize the tests in different files and just
provide a common fixture-like class to reuse functionality.
Also use this as an opportunity to rewrite the tests to use Catch
directly instead of using CppUnit-compatible macros.
Finally, actually build these tests as part of the test suite.
Drop the legacy CppUnit testing framework used for the unit tests.
Replacing it with Catch has the advantage of not requiring CppUnit
libraries to be installed on the system in order to be able to run
tests (Catch is header-only and a copy of it is now included in the
main repository itself) and, in the future, of being able to write
the tests in a much more natural way.
For now, however, avoid changing the existing tests code as much as
[reasonably] possible to avoid introducing bugs in them and provide
the CppUnit compatibility macros in the new wx/catch_cppunit.h header
which allow to preserve the 99% of the existing code unchanged. Some
of the required changes are:
- Decompose asserts using "a && b" conditions into multiple asserts
checking "a" and "b" independently. This would have been better
even with CppUnit (to know which part of condition exactly failed)
and is required with Catch.
- Use extra parentheses around such conditions when they can't be
easily decomposed in the arrays test, due to the use of macros.
This is not ideal from the point of view of messages given when
the tests fail but will do for now.
- Rewrite asserts using "a || b" as a combination of condition
checks and assert macros. Again, this is better anyhow, and is
required with Catch. Incidentally, this allowed to fix a bug in
the "exec" unit test which didn't leave enough time for the new
process to be launched before trying to kill it.
- Remove multiple CPPUNIT_TEST_SUITE_NAMED_REGISTRATION() macros,
our emulation of this macro can be used only once.
- Provide string conversions using Catch-specific StringMaker for
a couple of types.
- Replace custom wxImage comparison with a Catch-specific matcher
class.
- Remove most of test running logic from test.cpp, in particular don't
parse command line ourselves any longer but use Catch built-in
command line parser. This is a source of a minor regression:
previously, both "Foo" and "FooTestCase" could be used as the name of
the test to run, but now only the latter is accepted.
Chinese, Japanese etc translations use a special style for the menu mnemonics
and append them to the translated menu label in brackets, e.g. the menu label
could have the form of "<translation-of-file> (&F)".
Check for this style of mnemonics in wxStripMenuCodes() too and strip them as
well.
