Wine API: NtGdiSetVirtualResolution

NAME

NtGdiSetVirtualResolution (WIN32U.@)

 BOOL NtGdiSetVirtualResolution
 (
  HDC   hdc,
  DWORD horz_res,
  DWORD vert_res,
  DWORD horz_size,
  DWORD vert_size
 )

Undocumented on msdn.

Changes the values of screen size in pixels and millimeters used by the mapping mode functions.

`hdc`	[In]	Device context.
`horz_res`	[In]	Width in pixels (equivalent to `HORZRES` device cap).
`vert_res`	[In]	Height in pixels (equivalent to `VERTRES` device cap).
`horz_size`	[In]	Width in mm (equivalent to `HORZSIZE` device cap).
`vert_size`	[In]	Height in mm (equivalent to `VERTSIZE` device cap).

TRUE if successful. FALSE if any (but not all) of the last four params are zero.

This doesn't change the values returned by NtGdiGetDeviceCaps, just the scaling of the mapping modes.

Calling with the last four params equal to zero sets the values back to their defaults obtained by calls to NtGdiGetDeviceCaps.
