XIntersectRegion, XUnionRegion, XUnionRectWithRegion, XSubtractRegion,
XXorRegion, XOffsetRegion, XShrinkRegion - region arithmetic
SYNTAX
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
dest_region_return
Returns the destination region.
dr_return Returns the result of the computation.
dx
dy Specify the x and y coordinates, which define the amount you
want to the specified region.
r Specifies the region.
rectangle Specifies the rectangle.
sra
srb Specify the two regions with which you want to perform the
computation.
src_region
Specifies the source region to be used.
DESCRIPTION
The function computes the intersection of two regions.
The function computes the union of two regions.
The function updates the destination region from a union of the speci‐
fied rectangle and the specified source region.
The function subtracts srb from sra and stores the results in
dr_return.
The function calculates the difference between the union and intersec‐
tion of two regions.
The function moves the specified region by a specified amount.
The function reduces the specified region by a specified amount. Posi‐
tive values shrink the size of the region, and negative values expand
the region.
