## Discussion

Discussion The possible values for this property are listed in Scaling Filters. The default value of this property is linear. Figure 1 shows the difference between linear and nearest filtering when a 10 x 10 point image of a circle is magnified by a scale of 10.

The circle on the left uses linear and the circle on the right uses nearest.
