fg_restorew() (legacy function)

Win32 DirectX Fastgraph/Light

Prototype

void fg_restorew (double xmin, double xmax, double ymin, double ymax);

Sub fg_restorew (ByVal xmin As Double, ByVal xmax As Double, ByVal ymin As Double, ByVal ymax As Double)

procedure fg_restorew (xmin, xmax, ymin, ymax : real);

Description

The fg_restorew() legacy function copies a rectangular region, defined in 2D world 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

xmin is the world space x coordinate of the region's left edge.

xmax is the world space x coordinate of the region's right edge. It must be greater than or equal to the value of xmin.

ymin is the world space y coordinate of the region's bottom edge.

ymax is the world space y coordinate of the region's top edge. It must be greater than or equal to the value of ymin.

Return value

none
