.SH DESCRIPTION
.sp
.LP
The \fBmlib_ImageCreateSubimage()\fR function creates a mediaLib image data structure for a subimage based on a source image. Note that the memory space of the source image data is used for the subimage data. The data type of the image can be \fBMLIB_BIT\fR, \fBMLIB_BYTE\fR, \fBMLIB_SHORT\fR, \fBMLIB_USHORT\fR, \fBMLIB_INT\fR, \fBMLIB_FLOAT\fR, or \fBMLIB_DOUBLE\fR.
