There seems to be an issue with certain objects in the label images generated by <labelme_export_json> when opened with PIL.Image.open, where the labels and pixels don't match up correctly.

Provide environment information

Python 3.8.19
labelme 5.4.1
Pillow 10.1.0

What OS are you using?

Ubuntu 20.04.4

Describe the Bug

I found an interesting issue. The labels I annotated using Labelme appear normal in the PNG images generated by <labelme_export_json>, but when I open the label image using <lbl = np.asarray(PIL.Image.open(label_png))>, I notice that some pixel labels are incorrect. For example, the edges of some polygons or the centers of small objects have pixel label errors.

Expected Behavior

I hope that PIL.Image.open(label_png) will display the same image as the one generated by labelme_export_json.
