static void HOperatorSet.DispObj(HObject objectVal, HTuple windowHandle)

void HObject.DispObj(HWindow windowHandle)

void HWindow.DispObj(HObject objectVal)

def disp_obj(object: HObject, window_handle: HHandle) -> None

Description

disp_objdisp_objDispObjDispObjdisp_obj displays objects depending of their kind. disp_objdisp_objDispObjDispObjdisp_obj is equivalent to disp_imagedisp_imageDispImageDispImagedisp_image for one channel images, equivalent to disp_colordisp_colorDispColorDispColordisp_color for three channel images, equivalent to disp_regiondisp_regionDispRegionDispRegiondisp_region for regions and equivalent to disp_xlddisp_xldDispXldDispXlddisp_xld for XLDs.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Example (HDevelop)

* Output of a gray image:
read_image(Image1,'monkey')
disp_obj(Image1,WindowHandle)
threshold(Image,Region,0,128)
disp_obj(Region,WindowHandle)

Example (C)

/* Output of a gray image: */
read_image(&Image,"monkey");
T_disp_obj(Image,WindowHandle);
threshold(Image,&Region,0.0,128.0);
T_disp_obj(Region,WindowHandle);

Example (HDevelop)

* Output of a gray image:
read_image(Image1,'monkey')
disp_obj(Image1,WindowHandle)
threshold(Image,Region,0,128)
disp_obj(Region,WindowHandle)

Example (HDevelop)

* Output of a gray image:
read_image(Image1,'monkey')
disp_obj(Image1,WindowHandle)
threshold(Image,Region,0,128)
disp_obj(Region,WindowHandle)

Result

If the used object is valid and a correct output mode is set, disp_objdisp_objDispObjDispObjdisp_obj returns 2 ( H_MSG_TRUE) . Otherwise an exception is raised.
