CropSurfaceToRegion


Module: Vision3DStandard

Removes points that are not present in a given region.

Name Type Description
Input value inSurface Surface Input surface
Input value inRegion Region Region from which the points are not removed
Input value inPreserveDimensions Bool Flag indicating whether the surface dimensions should be preserved or not
Output value outSurface Surface Output surface

Description

The operation removes points from surface that are not contained in a given rectangular box within provided Region.
This operation is very similar to CropSurface, although it is slightly limited. Region within the surface will be cropped is viewed from above. This means that it is possible to edit the input within a two-dimensional space through the X and Y axis instead of X, Y and Z axis in CropSurface filter.
Flag inPreserveDimensions informs if the operation output should keep the original dimensions of its input. E.g. if inSurface has its Width=300, Height=200 and Pitch=608 and the flag is enabled, the outSurface will have exactly the same dimensions of 300x200x608. However, if the flag is disabled, outSurface will have its dimensions smaller to adjust them to surface size, but its XOffset, YOffset, ZOffset properties will be accordingly bigger in order to keep the surface in the same place in workspace.
