描述
get_partget_partGetPartGetPartGetPartget_part returns the upper left and lower right corner
of the image part shown in the window. The image part can be
changed with the operator set_partset_partSetPartSetPartSetPartset_part (Default is the
whole image).
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。

结果
get_partget_partGetPartGetPartGetPartget_part returns 2 (
H_MSG_TRUE)
if the window is valid.否则将抛出异常。
