Invert Structure

With Invert Structure you can easily switch solid voxels to pores and pores to solid voxels. Invert Structure interchanges background and structure voxels. Use this feature when treating images where background and structure values are permuted, e.g., some types of tomographic images.

Note-Important

Important! The Invert command in fact reassigns all materials with non-zero IDs to ID 00, and reassigns the material with ID 00 to Material ID 01. Only in the default situation where ID 00 denotes the pore space and non-zero IDs denote solid materials, this switches pore and solid phase. In any other situation, Invert will not work as intended and you have to use the Reassign Material ID command instead.

The analytic object (GAD) information is lost by inverting because all materials are mapped to void space in this case.
