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 mode. This mode is not supported by all
graphics cards. The graphics card must have sufficient extended memory because Direct3D 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 camera, see the How To Proceed:
Image Display section.
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()
