.SH DESCRIPTION
.sp
.LP
The \fBmlib_ImageZoomIn2X()\fR function enlarges the source image by a factor of two. It uses the interpolation method as described by the resampling filter.
.sp
.LP
The center of the upper-left corner pixel of an image is located at \fB(0.5, 0.5)\fR.
.sp
.LP
The width and height of the destination image can be different from those of the source image.
.sp
.LP
The center of the source image is mapped onto the center of the destination image.
