dmICCreate, dmICDestroy - create and destroy image converter context
DMstatus dmICCreate(int i, DMimageconverter *converter);
void dmICDestroy(DMimageconverter converter);
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.
