18 The mlib_VideoColorJFIFYCC2RGB444_S16() function performs color space
19 conversion from YCbCr to RGB when used in the JPEG File Interchange
20 Format (JFIF).
21
22
23 Both the input YCbCr components and the output RGB components are sup‐
24 posed to be in the range of [0, 4095].
25
26
27 The following equation is used:
28
29 R = Y + 1.40200 * (Cr - 2048)
30 G = Y - 0.34414 * (Cb - 2048) - 0.71414 * (Cr - 2048)
31 B = Y + 1.77200 * (Cb - 2048)
32

35 The function takes the following arguments:
36
37 rgb Pointer to destination RGB multi-component row. rgb must be
38 8-byte aligned.
39
40
41 y Pointer to source Y component row. y must be 8-byte aligned.
42
43
44 cb Pointer to source Cb component row. cb must be 8-byte aligned.
45
46
47 cr Pointer to source Cr component row. cr must be 8-byte aligned.
48
49
50 n Length of Y component row. The length of Cb and Cr component
51 rows must be n. The length of the RGB multi-component row must
52 be 3*n.
53
54
56 The function returns MLIB_SUCCESS if successful. Otherwise it returns
57 MLIB_FAILURE.
