fg_copypage()

Win32 DirectX Fastgraph/Light

Prototype

void fg_copypage (int source, int dest);

Sub fg_copypage (ByVal source As Long, ByVal dest As Long)

procedure fg_copypage (source, dest : integer);

Description

The fg_copypage() function transfers the contents of one virtual buffer to another virtual buffer with the same dimensions. Assuming maxx and maxy represent the maximum x and y coordinates of the virtual buffers, the call

fg_copypage(source,dest);

is equivalent to

fg_vbcopy(0,maxx,0,maxy,0,maxy,source,dest);

Parameters

source is the source virtual buffer handle.

dest is the destination virtual buffer handle.

Return value

none

Restrictions

The source and destination virtual buffers must have the same color depth and same dimensions. If they have the same color depth but not the same dimensions, use fg_vbcopy() instead of fg_copypage().

When using DirectX, the source or destination virtual buffers must not be locked.
