fg_restore() (legacy function)

Win32 DirectX Fastgraph/Light

Prototype

void fg_restore (int minx, int maxx, int miny, int maxy);

Sub fg_restore (ByVal minx As Long, ByVal maxx As Long, ByVal miny As Long, ByVal maxy As Long)

procedure fg_restore (minx, maxx, miny, maxy : integer);

Description

The fg_restore() legacy function copies a rectangular region, defined in screen space, from the background virtual buffer to the same position in the foreground virtual buffer. As with Fastgraph's other block transfer functions, no clipping is performed.

Parameters

minx is the x coordinate of the region's left edge.

maxx is the x coordinate of the region's right edge. It must be greater than or equal to the value of minx.

miny is the y coordinate of the region's top edge.

maxy is the y coordinate of the region's bottom edge. It must be greater than or equal to the value of miny.

Return value

none

Restrictions

When using DirectX, the background and foreground virtual buffers must not be locked.
