Syntax
INT is_FreezeVideo (HIDS hCam, INT Wait)
Description
is_FreezeVideo() acquires a single image from the camera. In DIB mode, the image is stored in the active
image memory. If ring buffering is used in DIB mode, the captured image is transferred to the next available image
m emory of the sequence. Once the last available sequence memory has been filled, the sequence event or
message will be triggered.
In Direct3D or OpenGL mode, the is directly copied to the graphics card buffer and then displayed.
Image capture will be started by a trigger if you previously enabled the trigger mode using
is_SetExternalTrigger() . A hardware triggered image acquisition can be cancelled using
is_StopLiveVideo() if exposure has not started yet.
For further information on the image capture modes of the DCx camera, see the How to proceed: Image capture
section.
