Syntax
INT is_SetVertFilter (HIDS hf, INT Mode)
Description
With is_SetVertFilter() the vertical interpolation filter is activated. This function is only useful when image scaling is switched on. To select a filter level, the bitwise operator OR is linked to IS_ENABLE_VERT_FILTER. Only level 1 is allowed at all resolutions for the vertical filters. Level 2 works to a maximum horizontal resolution of 385 pixel points and level 3 to a maximum horizontal resolution of 193 image points.
