NAME

sv_ip_zoom - magnify an image

The sv_ip_zoom object scales the input image in the x and y dimension by the xfactor and yfactor scales, with offsets xoff and yoff.

sv_ip_filter

xoff Offset for the x scaling.

yoff Offset for the y scaling.

xfactor Amount to scale in the x direction.

yfactor Amount to scale in the y direction.

interp_code Type of interpolation to perform. See the SunVision IP reference manual for details.
