#!N #!Rdxbb DXBoundingBox #!N #!N Function #!N #!N Computes the bounding
box of an Object. #!N #!N Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h>
Object DXBoundingBox(Object o, Point *box) #!EF #!N #!N Functional Details #!N
#!N This routine adds to Object #!F-adobe-times-bold-r-normal--18* o #!EF , and
any of its descendants that are Fields, a "box" component consisting
of an Array of 2(d) points that are the corners of
a bounding box (where #!F-adobe-times-medium-i-normal--18* d #!EF is the dimensionality of
the data). For data of dimensionality three or less, the routine
returns--in the Array pointed to by #!F-adobe-times-bold-r-normal--18* box #!EF --the eight
corner points; for dimensionalities of one or two, the extra dimensions
are treated as zero in the box returned by the routine.
#!N #!N The bounding box returned on #!F-adobe-times-bold-r-normal--18* o #!EF is
determined by combining the bounding boxes of all Fields contained in
#!F-adobe-times-bold-r-normal--18* o #!EF . #!N #!N Transformations are considered in computing
the bounding box, but clipping Objects are not. The bounding box
is not guaranteed to be the tightest possible. #!N #!N A
#!F-adobe-times-bold-r-normal--18* Point #!EF is defined as follows: #!N #!F-adobe-times-bold-r-normal--18* typedef struct
point { float x, y, z; } Point, Vector; #!EF #!N
#!N Return Value Returns #!F-adobe-times-bold-r-normal--18* o #!EF or returns #!F-adobe-times-bold-r-normal--18* NULL
#!EF and may or may not set an error code, depending
on the input. For example, it does not set an error
code if a bounding box cannot be defined for the given
input. #!N #!N See Also #!N #!N #!F-adobe-times-bold-r-normal--18* #!Ldxccvs,dxall1178 h DXChangedComponentValues, DXChangedComponentStructure #!EL , #!Ldxemf,dxall1200 h DXEmptyField #!EL
