ImageDev

RotateCenterImage2d

Applies a centered rotation of a given angle on a two-dimensional image.

Access to parameter description

This command is deprecated, it will be removed in ImageDev 2024.2.
You can use Rotate2d instead.

RotateCenterImage2d performs a rotation of an image by a user-defined angle using the image center as axis of rotation.
