The new pixel is an average of these neighboring pixels. With this type of downsampling, all pixels are compared and averaged to the center pixel.

Bicubic Downsampling uses a weighted average within a given area to determine pixel value.

It’s the fastest of the three methods but gives you the lowest quality.

Subsampling chooses the center pixel value within a sample area, then assigns it to the entire sample area.

The average pixel value is then assigned to the entire pixel area.

Downsampling averages pixels within a sample area.
