capDlgVideoDisplay
The capDlgVideoDisplay
macro displays a dialog box in which the user can set or adjust the video
output. This dialog box might contain controls that affect the hue, contrast,
and brightness of the displayed image, as well as key color alignment. You can
use this macro or explicitly send the WM_CAP_DLG_VIDEODISPLAY message.
BOOL capDlgVideoDisplay(

hwnd |

); |

Parameters
hwnd
Handle of a
capture window.
Return Values
Returns TRUE
if successful or FALSE otherwise.
Remarks
The controls
in this dialog box do not affect digitized video data; they affect only the
output or redisplay of the video signal.
The Video
Display dialog box is unique for each capture driver. Some capture drivers
might not support a Video Display dialog box. Applications can determine if the
capture driver supports this message by checking the fHasDlgVideoDisplay
member of the CAPDRIVERCAPS structure.
