Fix crash when doing a SaveLayer under a non-invertible transform #178507
Conversation
|
The check and comment failed to acknowledge that DLBuilder does not track the NOP status of the matrix which can also cause the Accumulate method to return false. See #178506 |

Code Review
This pull request addresses a crash in SaveLayer when used with a non-invertible transform. The fix involves removing a DCHECK that was based on a faulty assumption, which is the correct approach. The PR also includes a good set of unit tests that cover various scenarios leading to non-invertible matrices, such as zero scaling and linear skewing, which will help prevent regressions. My review includes a few suggestions to improve code style by adhering to const correctness as per the project's C++ style guide.
