/*
|
|||
|
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.
