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.
Don't use external image files, this makes it simpler to run the test
(it can be now done from any directory) and also experiment with it
(e.g. by making the test image fully transparent or fully opaque).
Remove the now unneeded .ico file but keep the .png one still used by
another test.
- 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.
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
Add the source files present in the bkl but not CMakeLists.txt to the
latter one too.
Also link with AUI library now that a test file using it is included.
Closes https://github.com/wxWidgets/wxWidgets/pull/2064
Rename all library targets to start with wx. This way it does not use generic
names like base or core that could interfere with other libraries that add
include the wxWidgets project.
Add CMake build system for libraries, tests and samples
update_files.py converts build/files into CMake format.
build/update-setup-h has been modified to update build/cmake/setup.h.in.
