IG_mult_frame_num_from_time

This function returns the number of the frame that would be visible at the given time under normal speed playback conditions.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_mult_frame_num_from_time_get( HIGMULT hMult, AT_UINT msTime, LPAT_UINT lpFrameNum );

Arguments:

Name	Type	Description
hMult	HIGMULT	Multimedia instance handle.
msTime	AT_UINT	Time in milliseconds (since the beginning).
lpFrameNum	LPAT_UINT	Frame number at given time.

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

This function does not process image pixels.

Example:

	Copy Code
/* Finds the # of the frame at 1 second from the beginning / AT_ERRCOUNT nErrcount; / Number of errors on stack / HIGMULT hMult; / Multimedia instance handle / AT_UINT frameNum; / Returned frame number */ nErrcount = IG_mult_frame_num_from_time_get(hMult, 1000, &frameNum);

Copy Code

/* Finds the # of the frame at 1 second from the beginning */
AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGMULT hMult;          /* Multimedia instance handle */
AT_UINT frameNum;       /* Returned frame number */
nErrcount = IG_mult_frame_num_from_time_get(hMult, 1000, &frameNum);
