17 The mlib_ImageZoomIn2X_Fp() function enlarges the floating-point source
18 image by a factor of two. It uses the interpolation method as described
19 by the resampling filter.
20
21
22 The center of the upper-left corner pixel of an image is located at
23 (0.5, 0.5).
24
25
26 The width and height of the destination image can be different from
27 those of the source image.
28
29
30 The center of the source image is mapped onto the center of the desti‐
31 nation image.
32
34 The function takes the following arguments:
35
36 dst Pointer to destination image.
37
38
39 src Pointer to source image.

41
42 filter Type of resampling filter. It can be one of the following:
43
44 MLIB_NEAREST
45 MLIB_BILINEAR
46 MLIB_BICUBIC
47 MLIB_BICUBIC2
48

50
51 edge Type of edge condition. It can be one of the following:
52
53 MLIB_EDGE_DST_NO_WRITE
54 MLIB_EDGE_DST_FILL_ZERO
55 MLIB_EDGE_OP_NEAREST
56 MLIB_EDGE_SRC_EXTEND
57 MLIB_EDGE_SRC_PADDED

62 The function returns MLIB_SUCCESS if successful. Otherwise it returns
63 MLIB_FAILURE.
