is_CaptureVideo
Syntax
INT is_CaptureVideo (HIDS hCam, INT Wait)
Description
is_CaptureVideo() digitises video images in real time and transfers the images to an allocated
image memory or, if Direct3D is used, to the graphics card. The image data (DIB mode) is stored in
the memory created using is_AllocImageMem() and designated as active image memory using
is_SetImageMem() . Using is_GetImageMem() , you can query the memory address.
If ring buffering is used, the image capturing function cycles through all image memories used for
storing the images of a capture sequence in an endless loop. Sequence memories locked by
is_LockSeqBuf() will be skipped. If the last available sequence memory has been filled, the
sequence event or message will be triggered. Capturing always starts with the first element of the
sequence.
For further information on the image capture modes of the DCx camera camera, see the How To
Proceed: Image Capture section.
