XIntersectRegion(3X11)XIntersectRegion(3X11)NAME
XIntersectRegion, XUnionRegion, XUnionRectWithRegion, XSubtractRegion,
XXorRegion, XOffsetRegion, XShrinkRegion - region arithmetic
SYNOPSIS
XIntersectRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XUnionRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XUnionRectWithRegion(rectangle, src_region, dest_region_return)
XRectangle *rectangle;
Region src_region;
Region dest_region_return;
XSubtractRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XXorRegion(sra, srb, dr_return)
Region sra, srb, dr_return;
XOffsetRegion(r, dx, dy)
Region r;
int dx, dy;
XShrinkRegion(r, dx, dy)
Region r;
int dx, dy;
ARGUMENTS
Returns the destination region. Returns the result of the computation.
Specify the x and y coordinates, which define the amount you want to
move or shrink the specified region. Specifies the region. Specifies
the rectangle. Specify the two regions with which you want to perform
the computation. Specifies the source region to be used.
DESCRIPTION
The XIntersectRegion function computes the intersection of two regions.
The XUnionRegion function computes the union of two regions.
The XUnionRectWithRegion function updates the destination region from a
union of the specified rectangle and the specified source region.
The XSubtractRegion function subtracts srb from sra and stores the
results in dr_return.
The XXorRegion function calculates the difference between the union and
intersection of two regions.
The XOffsetRegion function moves the specified region by a specified
amount.
The XShrinkRegion function reduces the specified region by a specified
amount. Positive values shrink the size of the region, and negative
values expand the region.
