void HWindow::DispObj( const HObject& Object ) const

void HObject.DispObj( HWindow windowHandle )

void HWindow.DispObj( HObject objectVal )

Description

disp_objDispObj displays objects depending of their kind. disp_objDispObj is equivalent to disp_imageDispImage for one channel images, equivalent to disp_colorDispColor for three channel images, equivalent to disp_regionDispRegion for regions and equivalent to disp_xldDispXld for XLDs.

Example

(HDevelop)

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

(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)\;

Result

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