Description Define the screen area for recording. Parameters left [in] The x-coordinate, in pixels, representing the upper-left corner of the screen capture region. top [in] The y-coordinate, in pixels, representing the upper-left corner of the screen capture region. right [in] The x-coordinate, in pixels, representing the lower-right corner of the screen capture region. bottom [in] The y-coordinate, in pixels, representing the lower-right corner of the screen capture region. The designated screen capture area excludes the right and bottom edges of the rectangle. Return Value None. Remarks Use this function to define the screen area for recording. You can invoke it either before starting a recording or during the recording process, allowing for dynamic adjustments to the recording area without interrupting the process. If the recording area is altered mid-recording, the video will automatically scale to maintain the original aspect ratio. Additionally, a smooth transitional visual effect is applied to the video to make the change in recording area appear less abrupt. By default, the entire desktop is set as the capture area. If an empty rectangle is set, it defaults to the desktop rectangle. A rectangle exceeding the desktop’s size will be trimmed to fit. To capture a specific window, call ScnLib_SetCaptureWnd(). To retrieve the exact coordinates of the recording region, call ScnLib_SelectCaptureRegionA/W(). To allow users to select a capture region on the screen, call ScnLib_SelectCaptureRegionA/W(). To make the recording region frame visible to the user, call ScnLib_ShowCaptureRegionFrame().
