IBasicVideo::put_SourceLeft method

The put_SourceLeft method sets the x-coordinate of the source rectangle.

Syntax


HRESULT put_SourceLeft(
  [in]  long SourceLeft
);

Parameters

SourceLeft [in]

Specifies the x-coordinate, in pixels.

Return value

Returns an HRESULT value. Possible values include the following.

Return codeDescription
E_INVALIDARG

Invalid argument.

S_OK

Success.

VFW_E_NOT_CONNECTED

The video renderer's input pin is not connected.

 

Remarks

This method moves the entire source rectangle to the left or right. It does not change the width of the source rectangle. If the value of SourceLeft would place the right edge of the rectangle beyond the edge of the video frame, the method returns E_INVALIDARG. To crop the video, call put_SourceWidth to adjust the width, before calling put_SourceLeft. (Or call SetSourcePosition to set the entire source rectangle at once.)
