Output(OS_ROUNDRECT)

WORD Output(
  LPPDEVICE lpDestDev, 
  WORD wStyle, 
  WORD wCount, 
  LPPOINT lpPoints, 
  LPPPEN lpPPen, 
  LPPBRUSH lpPBrush, 
  LPDRAWMODE lpDrawMode, 
  LPRECT lpClipRect
 );
 

Draws and fills a rectangle that have rounded corners.

• Returns one of these values:

lpDestDev

Address of a PDEVICE or PBITMAP structure that specifies the destination device or bitmap.

wStyle

Must be OS_ROUNDRECT.

lpPoints

Address of an array of three POINT structures that represents the corners of the rectangle and the width and height of the ellipse used to draw the corners.

lpPPen

Address of a PPEN structure that specifies the physical pen that is used to draw the border of the rectangle.

lpPBrush

Address of a PBRUSH structure that specifies the physical brush that is used to fill the rectangle.

lpDrawMode

Address of a DRAWMODE structure that contains the drawing information that is used to draw and fill the rectangle.

lpClipRect

Address of a RECT structure that contains coordinates for the clipping rectangle. If the lpClipRect parameter is NULL, the clipping rectangle is the entire display surface.

GDI calls this function when an application calls the RoundRect function (GDI.28).

The graphics driver must support the OS_ROUNDRECT style if the CC_ROUNDRECT value is set in the dpCurves member of the GDIINFO structure.

The Output function fills the interior of the rectangle first, then draw the border. Before filling and drawing, Output must subtract one from the bottom and right coordinates. GDI requires that rectangles are draw so that the border lies one pixel within the specified right and bottom edges.
