in our (Windows) software, pdf-files can be displayed via OLE (OleDraw api call). The user can define a rectangle and a pdf file and then this pdf file is drawn inside the rectangle. With adobe reader 9 and before this worked as expected. When the rectangle with the pdf was rescaled in our application, the pdf was automatically rescaled as well (so that the pdf always filled the complete rectangle). Now with adobe reader X this does not work any more. When the rectangle is rescaled the size of the pdf in the rectangle stays the same (so that there is either a lot of free space or the pdf is clipped at the border of the rectangle).
Does anyone have an idea what we have to change in order to reproduce the behaviour of earlier reader versions with adobe reader X?
