ActiveID VFW Example CodeUsing ActiveID is quick and simple, for example in Visual Basic to start a preview on your first capture device (Webcam, CCD, etc. ) Just write 1 line of code.ctlActID.PreviewStart 0 To change the preview size to 320x240 resolution just write: ctlActID.RequestedWidth = 320 ctlActID.RequestedHeight = 240 ctlActID.UpdateFormat And to set the viewable preview size to that of your ID card or badges requirements simply write: ctlActID.ViewableWidth = 100 ctlActID.ViewableHeight = 120 ctlActID.UpdateFormat Or simply set the Requested and Viewable properties before the PreviewStart method to automate the process. ctlActID.RequestedWidth = 320 ctlActID.RequestedHeight = 240 ctlActID.ViewableWidth = 100 ctlActID.ViewableHeight = 120 ctlActID.PreviewStart 0 Anytime during the preview to capture an image using ActiveID call the saveBMP or saveJPEG methods. ctlActID.saveBMP "stringFilename" or ctlActID.saveJPEG "stringFilename", intQuality Where stringFilename is the drive, directory and filename you wish to save to and intQuality is a number between 1 and 100 for setting the quality of JPEG images. |
