ICameraControl::put_Roll method (vidcap.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The put_Roll method sets the camera's roll angle.

Syntax

HRESULT put_Roll(
  [in] long Value,
  [in] long Flags
);

Parameters

[in] Value

Specifies the roll angle, in degrees. Positive values are clockwise along the image viewing axis, and negative values are counter clockwise. Theoretical values range from –180 degrees to +180 degrees, but the actual range depends on the camera. See ICameraControl::getRange_Roll.

[in] Flags

Zero or more flags. See CameraControlFlags. If the CameraControl_Flags_Auto flag is used, the Value parameter is ignored and the camera sets the default value.

Return value

Returns an HRESULT value.
