DESCRIPTION

20       The mlib_ImageZoomTranslateTable_Fp() function will enlarge  or  minify
21       the  floating-point  source  image  by  the  X and Y zoom factors, with
22       translation. It uses a table, interp_table, to do interpolation.
23
24
25       It uses the following equation for coordinate mapping:
26
27         xd = zoomx*xs + tx
28         yd = zoomy*ys + ty
29
30
31
32       where a point with coordinates (xs, ys) in the source image  is  mapped
33       to a point with coordinates (xd, yd) in the destination image.
34
35
36       The data type of the images can be MLIB_FLOAT or MLIB_DOUBLE.
37
38
39       The width and height of the destination image can be different from the
40       width and height of the source image.
41
42
43       The center of the upper-left corner pixel of an  image  is  located  at
44       (0.5, 0.5).
45

PARAMETERS

47       The function takes the following arguments:
48
49       dst             Pointer to destination image.
50
51
52       src             Pointer to source image.
53
54
55       zoomx           X zoom factor. zoomx > 0.
56
57
58       zoomy           Y zoom factor. zoomy > 0.
59
60
61       tx              X translation.
62
63
64       ty              Y translation.
65
66
67       interp_table    Pointer to an interpolation table. The table is created
68                       by the mlib_ImageInterpTableCreate() function.
69
70
71       edge            Type of edge condition. It can be one of the following:
72
73                         MLIB_EDGE_DST_NO_WRITE
74                         MLIB_EDGE_DST_FILL_ZERO
75                         MLIB_EDGE_OP_NEAREST
76                         MLIB_EDGE_SRC_EXTEND
77                         MLIB_EDGE_SRC_EXTEND_INDEF
78                         MLIB_EDGE_SRC_PADDED
79
80
81

RETURN VALUES

83       The function returns MLIB_SUCCESS if successful. Otherwise  it  returns
84       MLIB_FAILURE.
