Subject: [PATCH 065/181] tests: Fix image writing on big endian
|
|
|
|
The code tried to only write the RGB bytes of FORMAT_RGB24, however, the
|
|
in-memory layout is different on big-endian which would result in the
|
|
wrong bytes being written.
|
|
|
|
Fix this by simply also writing the byte we do not care about.
