Non-Multiple-of-8 Dimensions Cause Errors in Custom Pipeline

[zixuzhuang]

Description
When using a custom pipeline that reads masks, images with dimensions that are not multiples of 8 cause critical issues. Specifically:

The software may freeze when processing such images.
The mask regions may be distorted into abnormal slanted shapes instead of being correctly processed.
This issue significantly impacts workflows that require precise mask handling.

Steps to Reproduce
Use a custom pipeline that processes masks.
Input an image with dimensions that are not multiples of 8.
Observe the system behavior: it either hangs (e.g., 1215x1836) or incorrectly distorts the mask region (e.g., 763x1220).

Expected Behavior
The software should handle non-multiple-of-8 dimensions gracefully.
The mask should retain its correct shape without distortion.
