dmIC(3dm)							     dmIC(3dm)

NAME    [Toc]    [Back]

     dmICCreate, dmICDestroy - create and destroy image	converter context

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/dm_imageconvert.h>

     DMstatus dmICCreate(int i,	DMimageconverter *converter);

     void dmICDestroy(DMimageconverter converter);

DESCRIPTION    [Toc]    [Back]

     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

     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.
