Detailed Description

Zooms in on the source image x/m_YZoom is the amount to zoom - 1 = full size, 2 = double size, 4 = quad size both zoom factors should normally be equal - any other values will wreck the aspect ratio of the image (that would be a shame after spending all this code to keep it correct x/m_YPos is the position to zoom in on - 0 = left/top of frame, .5 = middle, 1 = right/bottom of frame Normally this filter will be applied just before the CScreenSanityAspectFilter

Member Function Documentation

BOOL CPanAndZoomAspectFilter::adjustAspect (  CAspectRectangles &  ar  )  [virtual]

Called to actually perform the adjustment for 1 filter If it returns TRUE, this is a request from the filter to re-run the aspect calculation The TRUE Value is currently only used by the filter which adjusts the window rectangle as this adjustment affects all calculations. Current implementation only allows 1 level of re-calculate requests. Implements CAspectFilter.
