[PATCH v2 0/1] MR3774: gdiplus/tests: Extend DrawImage scaling tests.
Changing the colour of the second pixel of the source bitmap clarifies the incorrect behaviour of PixelOffsetMode Half and HighQuality. This also provides better proof that PixelOffsetMode None and Fast are implemented correctly. Extending tests is starting point for further improvements of implementation pixel offset modes to match implementation from native gdiplus. -- v2: gdiplus/tests: Extend DrawImage scaling tests. https://gitlab.winehq.org/wine/wine/-/merge_requests/3774

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. 2 TestBot errors prevented a full analysis of your patch. If the test caused the operating system (e.g. Windows) to crash or reboot you will probably have to modify it to avoid that. Other issues should be reported to the TestBot administrators. The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=151848 Your paranoid android. === build (build log) === error: patch failed: dlls/gdiplus/tests/image.c:4799 Task: Patch failed to apply === debian11 (build log) === WineRunWineTest.pl:error: Could not send 'patch.diff' to the VM: network read timed out (sendfile/connect:AgentVersion.h:0/9) WineRunWineTest.pl:error: BotError: The test VM has crashed, rebooted or lost connectivity (or the TestAgent server died) WineRunWineTest.pl:error: Giving up after 3 run(s) === debian11b (build log) === WineRunWineTest.pl:error: Could not send 'patch.diff' to the VM: network read timed out (sendfile/connect:AgentVersion.h:0/9) WineRunWineTest.pl:error: BotError: The test VM has crashed, rebooted or lost connectivity (or the TestAgent server died) WineRunWineTest.pl:error: Giving up after 3 run(s)

The code changes looks good to me. I will suggest some changes to the commit message to make it a little easier to read: ``` gdiplus/tests: Extend DrawImage scaling tests. Changing the colour of the second pixel of the source bitmap clarifies the incorrect behaviour of PixelOffsetMode Half and HighQuality. This also provides better proof that PixelOffsetMode None and Fast are implemented correctly. ``` The original last paragraph (about further improvements) is useful information for the MR, but not for the commit. Thanks. Fixed
