Version used: XnView MP 1.9.2 64-Bit, Nconvert 7.221 64-Bit
actual behavior
Created resize action to resize 50% width

Image size 3840x2160 should be 1920x1080 after resize.
Code: Select all
nconvert.exe" -ratio -rtype lanczos -resize 50%% 100%%

expected behavior
The resized image should be 1920x1080. Actually I have no idea how to achieve this with Nconvert.
Code: Select all
-resize w h : Scale width-height
w h can be percent (ex: -resize 100% 200%)
w h can be cm (ex: -resize 100cm 200cm)
w h can be mm (ex: -resize 100mm 200mm)
w h can be inches (ex: -resize 100i 200i)
-resize fill w h : Scale by filling the box wxh
-resize longest size : Scale longest side
-resize shortest size : Scale shortest side
-resize dpi value : Scale to DPI
