The SaveToFile method

SaveToFile method is in use to save in file the frame from camera receiving in the data parameter of FRAME_SENT event.

Syntax of method invocation:

function SaveToFile (path: String, data: String, param : Boolean)

Saving of frame is also can be performed using the GET_FRAME reaction of the CAM object. It is required to specify the path for saving file with frame in the path parameter of this reaction. FRAME_SENT event is created in the system if the GET_FRAME reaction has not got the path parameter. In the data parameter of the FRAME_SENT event the video image frame which is to be saved using the SaveToFile method is stored.

The reaction allows exporting of video image frame even if the camera is not displaying in the Monitor window.

Method argument:

1. path – mandatory argument. Specifies the full path to save the file with frame.
2. data – mandatory argument. Specifies data to save in file.
3. param – mandatory argument. Defines necessity of conversion from base 64 format before saving. Possible parameter values:
   1. true – decode from base64 before saving;
   2. false – save string without conversion.

Time of frame saving depends on the anchor frames frequency. The higher the anchor frames frequency, the less time.

if (Event.SourceType == "CAM" && Event.SourceId == "1" && Event.Action == "FRAME_SENT")
 {
 SaveToFile("D:\\test.jpg",Event.GetParam("data"),true);
