ApplyDBScaleAndMove()

void MythVideoBounds::ApplyDBScaleAndMove ( void  )

private

Apply scales and moves for "Overscan" and "Underscan" DB settings.

It doesn't make any sense to me to offset an image such that it is clipped. Therefore, we only apply offsets if there is an underscan or overscan which creates "room" to move the image around. That is, if we overscan, we can move the "viewport". If we underscan, we change where we place the image into the display window. If no over/underscanning is performed, you just get the full original image scaled into the full display area.

Rotate()

void MythVideoBounds::Rotate ( void  )

private

Adjust various settings to facilitate portrait mode calculations.

This mimics rotating the screen around the video. While more complicated than simply adjusting the video dimensions and aspect ratio, this retains the correct video rectangle for use in the VideoOutput classes.

Note

To prevent a loss of precision over multiple passes, the original display aspect ratio should be retained elsewhere.
