void GsSetOrign (
int x,
int y
)
|
Arguments
| x |
Screen origin position X |
| y |
Screen origin position Y |
Return Value
None.
Explanation
The screen origin specified by (x, y) is set as the drawing offset
in the global variable POSITION.
GsSetOrign() sets the drawing offset in the global variable
POSITION but it does not set it in
the GPU. In other words, the new offset will not take effect until a function
such as GsSetDrawBuffOffset() that
sets the GPU drawing offset is called. The offset value in the global variable
POSITION is valid until GsSetOrgn()
is called again. The offset specified by (x, y) is relative within
the double buffer. In other words, the values (x, y) are added to
the double buffer base. In reality, the offset is set by the offx and offy
members of the global variable POSITION.
Notes
The third argument of GsInitGraph() determines
whether the offset is executed by GTE or by GPU and is specified using
GsOFSGTE (#defined as 0 in libps.h) or GsOFSGPU (#defined
as 4 in libps.h), respectively.
