DCx Cameras
4.3.80 is_SetDisplayMode
Syntax
INT is_SetDisplayMode (HIDS hCam, INT Mode)
Description
Using is_SetDisplayMode(), you can set the way in which images will be displayed on the screen.
For live videos including overlays, you can use the Direct3D or OpenGL mode. These modes are not supported by
all graphics cards. The graphics card must have sufficient extended memory because the overlay mode requires
additional memory up to the size needed for the current screen resolution.
For further information on the display modes of the DCx camera, see the How to proceed: Image display
section.
Attention
The Direct3D display mode is not available on Linux operating systems.
Note
We recommend that you call the following functions exclusively from a single thread in order to avoid unpredictable
behaviour of the application.
is_InitCamera()
is_SetDisplayMode()
is_ExitCamera()
