名称

change_domainchange_domainChangeDomainChangeDomainchange_domain — 更改图像的定义域。

签名

描述

The operator change_domainchange_domainChangeDomainChangeDomainChangeDomainchange_domain uses the indicated region as the new definition domain. Unlike the operator reduce_domainreduce_domainReduceDomainReduceDomainReduceDomainreduce_domain it does not form the intersection of the previous definition domain, i.e., the size of the matrix is not changed. This implies in particular, that the region must not exceed the image matrix, otherwise using such inconsistent iconic objects during subsequent operations will likely lead to errors or system crashes.

注意

Due to running time the transferred region is not checked for consistency (i.e., whether it fits with the image matrix). Incorrect regions lead to system hang-ups during subsequent operations.

执行信息

• 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.
