Hi Thanh,
We would like to inform you that
in the MAUI PDF Viewer, annotations automatically maintain their z-order by
default. When a new annotation is added, it is placed at the top of the stack,
with a z-order index one higher than the previous annotations on the page.
Additionally, when you select an annotation, it is brought to the front, above
all other annotations on the page. Once deselected, it returns to its original
position in the z-order. Due to this behavior, we do not provide an API to
customize the z-order index.
Please let us know if you need any
further clarification.
Regards,
Manikandan M
