Define Viewport

\i C V D byte::viewport byte::orientation word::width word::height

Parameter	Type	Range	Description
viewport	byte	1 ... 8	index of the viewport
orientation	byte	0 ... 3	orientation of the viewport
width	word	0 ... display width	width of the viewport
height	word	0 ... display height	height of the viewport

Defines a viewport with origin at the current cursor position.

You may define and use up to 8 viewports.
A viewport is always defined on the currently active draw screen (see Set Draw Screen).
The maximum values for width and height depend on the LCD-Screen used. If one of these values exceeds the screen dimension the viewport will not be defined and a [NACK] will be reported.
The viewport's orientation is interpreted relative to the screen orientation (see Set Screen Orientation).
Any other orientation than 0 will rotate the viewport around the cursor position and accordingly swap width and height (see Concept of Viewports).
All defined Viewports are automatically removed on startup and by the commands Reset All or Reboot Panel Controller.

Response:

[ACK]
