fg_savew() (legacy function)

Win32 DirectX Fastgraph/Light

Prototype

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

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

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

Description

The fg_savew() legacy function copies a rectangular region, defined in 2D world space, from the foreground virtual buffer to the same position in the background 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
