Syntax

INT is_FreezeVideo (HIDS hf, INT Wait)

Description

is_FreezeVideo() digitizes an image and transfers it to the active image memory. In DirectDraw mode the image is digitized in the DirectDraw buffer (either on the VGA card or in a back buffer). When working with ring buffering, image acquisition only takes place in the first image memory of the sequence.

| Note to EAGLE If the frame grabber is in trigger mode (see also is_SetExternalTrigger()), an image is only digitized, when a trigger signal occurs.

Parameters

hf | Frame grabber handle
| Wait
IS_WAIT | The function waits until an image is grabbed
IS_DONT_WAIT | The function returns straight away
10 < Wait < 32768 | Timeout in 10 ms steps. A maximum of 328,68 s can be waited. (This is approx. 5 min. and 20 s). For 1 < Wait < 10, Wait becomes equal to 10. (Example: Wait = 100 > wait 1 s)

Return value

IS_SUCCESS, IS_NO_SUCCESS
