- * Copyright (C) 1994-1996, Thomas G. Lane.

- * This file is part of the Independent JPEG Group's software.
- * For conditions of distribution and use, see the accompanying README file.
- *
- * This file contains code for merged upsampling/color conversion.
- *
- * This file combines functions from jdsample.c and jdcolor.c;
- * read those files first to understand what's going on.
- *
- * When the chroma components are to be upsampled by simple replication
- * (ie, box filtering), we can save some work in color conversion by
- * calculating all the output pixels corresponding to a pair of chroma
- * samples at one time.  In the conversion equations
- *	R = Y           + K1 * Cr
- *	G = Y + K2 * Cb + K3 * Cr
- *	B = Y + K4 * Cb
- * only the Y term varies among the group of pixels corresponding to a pair
- * of chroma samples, so the rest of the terms can be calculated just once.
- * At typical sampling ratios, this eliminates half or three-quarters of the
- * multiplications needed for color conversion.
- *
- * This file currently provides implementations for the following cases:
- *	YCbCr => RGB color conversion only.
- *	Sampling ratios of 2h1v or 2h2v.
- *	No scaling needed at upsample time.
- *	Corner-aligned (non-CCIR601) sampling alignment.
- * Other special cases could be added, but in most applications these are
- * the only common cases.  (For uncommon cases we fall back on the more
- * general code in jdsample.c and jdcolor.c.)
