[edk2-devel] [PATCH] MdeModulePkg/FrameBufferBltLib: Correctly consider SourceX
Posted by Marvin Häuser 4 years, 6 months ago
From: Marvin Haeuser <mhaeuser@outlook.de>

Currently, SourceX is not considered in the BufferToVideo operation
when the 8-bit pixel format is used. Correctly add the resulting
offset to prevent image corruption.

Hello Marvin,

In the future, could you help to run the below script:
BaseTools/Scripts/GetMaintainer.py
to get the reviewers for the proposed patch? Thanks in advance.

Hello Zhichao and Ray,

Could you help to take a look at this patch? Thanks.

Best Regards,
Hao Wu

I have just viewed a same patch of this issue. See https://edk2.groups.io/g/devel/topic/34168097#47297.
The two patches are doing the same thing.

Thanks,
Zhichao

Yes. The 2 patches look the same to me.

Since the above patch has been reviewed and tested, I will push the above one
later if there is no other comments.
