DESCRIPTION

17       The mlib_ImageZoomIn2X() function enlarges the source image by a factor
18       of two. It uses the interpolation method as described by the resampling
19       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.
