範例檔如下
case rdgPreferredVideoSize.ItemIndex of 0: VideoGrabber.UseNearestVideoSize (0, 0, chkStretchPreferredVideoSize.Checked); // disables the nearest size feature, uses the device's VideoSize index in the VideoSizes list 1: VideoGrabber.UseNearestVideoSize ( 88, 60, chkStretchPreferredVideoSize.Checked); 2: VideoGrabber.UseNearestVideoSize ( 88, 72, chkStretchPreferredVideoSize.Checked); 3: VideoGrabber.UseNearestVideoSize (180, 120, chkStretchPreferredVideoSize.Checked); ........... .................. end;
video size會跟這變 我的如下 case rdgPreferredVideoSize.ItemIndex of 0: begin VideoGrabber1.Width:=88; VideoGrabber1.Height:=60; VideoGrabber1.UseNearestVideoSize (88, 60, true); end; 1:begin VideoGrabber1.Width:=180; VideoGrabber1.Height:=144; VideoGrabber1.UseNearestVideoSize (180, 144, true); end; 2:begin VideoGrabber1.Width:=320; VideoGrabber1.Height:=240; VideoGrabber1.UseNearestVideoSize (320, 240, true); end; 3:begin VideoGrabber1.Width:=640; VideoGrabber1.Height:=480; VideoGrabber1.UseNearestVideoSize (640, 480, true); end; 4:begin VideoGrabber1.Width:=720; VideoGrabber1.Height:=576; VideoGrabber1.UseNearestVideoSize (720, 576, true); end; 5:begin VideoGrabber1.Width:=755; VideoGrabber1.Height:=620; VideoGrabber1.UseNearestVideoSize (755, 620, true); end; // you can add your own preferred formats end; VideoGrabber1.StartPreview; 為何我需要加 VideoGrabber1.Width:= VideoGrabber1.Height:= 而範例的不需要~~~那邊沒設定到嗎? |
