The Rect::Inflate method expands the rectangle by dx on the left and right edges, and by dy on the top and bottom edges.

Syntax

VOID Inflate(
  [in]  INT dx,
  [in]  INT dy
);

Parameters

dx [in]
Type: INT

Integer that specifies the amount to expand the rectangle on the left and right edges.
dy [in]
Type: INT

Integer that specifies the amount to expand the rectangle on the top and bottom edges.

Return value

This method does not return a value.

Remarks

The x-coordinate of the left edge is decreased by dx, and the x-coordinate of the right edge is increased by dx. The y-coordinate of the top edge is decreased by dy and the y-coordinate of the bottom edge is increased by dy.

Examples

The following example creates a Rect object, draws the rectangle, inflates the rectangle, and then redraws the rectangle.

VOID Example_InflateDxDy(HDC hdc)
{
   Graphics graphics(hdc);
   Pen pen(Color(255, 0, 0, 0));

   // Create and draw a rectangle.
   Rect rect(100, 100, 80, 40);
   graphics.DrawRectangle(&pen, rect);

   // Inflate the rectangle, and then redraw the rectangle.
   rect.Inflate(20, 10);
   graphics.DrawRectangle(&pen, rect);
}
