NAME
     dmICCreate, dmICDestroy - create and destroy image converter context

SYNOPSIS
     #include <dmedia/dm_imageconvert.h>

     DMstatus dmICCreate(int i, DMimageconverter *converter);

     void dmICDestroy(DMimageconverter converter);

DESCRIPTION
     dmICCreate creates an image converter context.  The actual selection of
     an image converter is separate from this operation.  The i argument
     specifies the image converter to create and is a value in the range of 0
     to one less than the return value of dmICGetNum. The return value of
     dmICChooseConverter is always valid directly in dmICCreate.

     NOTE: The i value for a given image converter may change at any time.

     The converter argument is the address of a caller supplied data structure
     for for use as a handle in subsequent operations on this image converter
     context.

     A process may have multiple image converters open simultaneously as well
     as multiple contexts of the same image converter.  However, a given image
     converter may itself limit the number of simultaneous open contexts on
     both a per process and per system basis.

     dmICDestroy frees the image converter context.  No further operations are
     valid on this handle.  The caller is responsible for deallocating the
     storage for converter.
