描述
算子 gen_rectangle1gen_rectangle1GenRectangle1GenRectangle1GenRectangle1gen_rectangle1 generates one or more rectangles parallel
to the coordinate axes which are described by the upper left corner
(Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1) and the lower right corner
(Row2Row2Row2Row2row2row_2, Column2Column2Column2Column2column2column_2).
More than one region can be created by passing a tuple of corner points.
The coordinate system runs from (0,0) (upper left corner) to
(Width-1,Height-1). See get_systemget_systemGetSystemGetSystemGetSystemget_system
and reset_obj_dbreset_obj_dbResetObjDbResetObjDbResetObjDbreset_obj_db in this context.
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。

示例（HDevelop）
* Contrast improvement in a rectangular region of interest
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
read_image(Image,'mreut')
dev_display (Image)
draw_rectangle1(WindowHandle,Row1,Column1,Row2,Column2)
gen_rectangle1(Rectangle,Row1,Column1,Row2,Column2)
reduce_domain(Image,Rectangle,Mask)
emphasize(Mask,Emphasize,9,9,1.0)
dev_display (Emphasize)
结果
如果参数值正确，算子 gen_rectangle1gen_rectangle1GenRectangle1GenRectangle1GenRectangle1gen_rectangle1 返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
The clipping according to the current image format is set via the
operator set_system('clip_region',<'true'/'false'>)set_system("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)set_system("clip_region",<"true"/"false">)。
