#define REENTRANT_MODE 1
/*
    DESCRIPTION OF COMPILER FLAG REENTRANT_MODE:

    //#define REENTRANT_MODE 1

    This compiler flag is related to the capability of banded decode 
    (decoding only one MB row of the source JPEG XR image at a time). 
	
    With REENTRANT_MODE defined, the decoder decodes one MB row on each call to 
    ImageStrDecDecode().
    
    The decoder acts as if it can only write to the single MBRow whose pointer was passed to it. 
    This acts as a proof of concept that the API would work if you passed it a small buffer 
    on each call to ImageStrDecDecode(). 
	
    The REENTRANT_MODE flag only works when the output image is in Orientations 0, 1 
    (vertically	flipped) or 2 (horizontally flipped).

    With REENTRANT_MODE defined, the function PKImageDecode_Copy_WMP()
    decodes only as far as the pRect parameter indicates. The width of the rectangle must be the width
    of the image, but on each call, this function will decode the image up to the end of the MB Row 
    which contains the i-th pixel row, where i = pRect->Y. 

    A target use of this version would be to have PKImageDecode_Copy_WMP() called in a loop, once for
    each MB row. On each call, pRect would specify a 1-MB-Row-tall rectangle that is the width of the 
    image. The decoder state is preserved until the Decoder finishes decoding the image.

    If, at a certain point, a request is made for a rectangle _above_ the last row decoded, then the
    decoder instance is terminated and re-initiated, and decoding re-starts, going from the beginning 
    of the image to the end of the current rectangle.

    ***

    We've chosen to uncomment-out this definition in this header file.  An alternate method would be
    to allow the user to define this in the PREPROCESSOR DEFINITIONS section of the properties page
    for each of the following projects: CommonLib, DecodeLib, JXRDecApp and JXRGlueLib.
