def rectangle1_domain(image: HObject, row_1: int, column_1: int, row_2: int, column_2: int) -> HObject

Description

The operator rectangle1_domainrectangle1_domainRectangle1DomainRectangle1Domainrectangle1_domain reduces the definition domain of the given image to the specified rectangle. The size of the matrix is not changed.

Execution Information

• Supports objects on compute devices.
• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on tuple level.
