 #!Rdxqosm DXQueryOriginalSizes, DXQueryOriginalMeshExtents #!N #!N Function #!N #!N Returns information about 
the size of the original Field used as the input to 
 #!F-adobe-times-bold-r-normal--18*   DXGrow #!EF . #!N #!N Syntax #!N  #!F-adobe-times-bold-r-normal--18*   #include <dx/dx.h> 
Field DXQueryOriginalSizes(Field f, int *positions, int *connections) Field DXQueryOriginalMeshExtents(Field f, int 
*offsets, int *sizes) #!EF #!N #!N Functional Details #!N #!N Returns 
information about the size of the original Field used as the 
input to  #!F-adobe-times-bold-r-normal--18*   DXGrow #!EF . The parameter  #!F-adobe-times-bold-r-normal--18*   f #!EF 
names a Field that was produced by  #!F-adobe-times-bold-r-normal--18*   DXGrow #!EF . 
In the case of  #!F-adobe-times-bold-r-normal--18*   DXQueryOriginalSizes #!EF , if  #!F-adobe-times-bold-r-normal--18*   positions 
#!EF is not  #!F-adobe-times-bold-r-normal--18*   NULL #!EF , the number of positions 
in the original Field is returned in  #!F-adobe-times-bold-r-normal--18*   *positions #!EF . 
If  #!F-adobe-times-bold-r-normal--18*   connections #!EF is not  #!F-adobe-times-bold-r-normal--18*   NULL #!EF , the 
number of interpolation elements in the original Field is returned in 
 #!F-adobe-times-bold-r-normal--18*   *connections #!EF . This is particularly useful in the case 
of irregular data. #!N #!N In the case of data defined 
on a regular mesh of connections,  #!F-adobe-times-bold-r-normal--18*   DXQueryOriginalMeshExtents #!EF can be 
used to obtain the offsets of the original Field relative to 
the grown Field, and the sizes of the original Field. If 
 #!F-adobe-times-bold-r-normal--18*   offsets #!EF is not  #!F-adobe-times-bold-r-normal--18*   NULL #!EF , the offset 
in each dimension of the original Field is returned in the 
Array pointed to by  #!F-adobe-times-bold-r-normal--18*   offsets #!EF ; if  #!F-adobe-times-bold-r-normal--18*   sizes 
#!EF is not  #!F-adobe-times-bold-r-normal--18*   NULL #!EF , the size in each 
dimension of the original Field is returned in the Array pointed 
to by  #!F-adobe-times-bold-r-normal--18*   offsets #!EF . #!N #!N Typically, data is 
grown so that neighborhood information is available during the calculation of 
a result for some original point (or connection) in the Field. 
The information returned by these routines identifies the portion of the 
grown Field that belonged to the original Field and that will 
remain after a later call to  #!F-adobe-times-bold-r-normal--18*   DXShrink #!EF . Thus, 
the caller can use this information to process only that portion 
of the Field that will remain after a later call to 
 #!F-adobe-times-bold-r-normal--18*   DXShrink #!EF . #!N #!N Return Value #!N #!N Returns 
 #!F-adobe-times-bold-r-normal--18*   f #!EF if it is a grown field or returns 
 #!F-adobe-times-bold-r-normal--18*   NULL #!EF (without setting an error code) if it not; 
otherwise, returns  #!F-adobe-times-bold-r-normal--18*   NULL #!EF and sets an error code. #!N
