wsic version: v0.6.1
Python version: 3.10
Operating System: Ubuntu 20.04

Description

By inspecting the jp2 metadata I see the Capture X Resolution is 36364 and the unit is cm. The corresponding MPP is 0.275 However, In the code, the resolution box reads 3636400 and an MPP of approx. 0.00275.

What I Did

wsic convert -i in.jp2 -o out.tiff -rt 4096 4096 -w 2 --no-ome --overwrite -to 180 -c jpeg -cl 95 -d 2 -d 4 -d 8
