dev_display — Displays image objects in the current graphics window.
dev_display(Object : : : )
dev_display displays an iconic object (image, region, or XLD)
in the active graphics window. This is equivalent to a double click
on an icon variable inside the variable window.
Using the code export feature of HDevelop, the code that is generated
for this operator may have a different behavior than the related
HALCON operator.
For a detailed description of the code export of HDevelop graphics
operators into the different programming languages see in the
“HDevelop User's Guide” the chapter Code Export
-> General Aspects of Code Generation
