Blur Node.

The Blur node blurs an image, providing several blur modes.

入力

Image(画像)

標準のイメージ入力です。

Size(サイズ)

The optional Size input will be multiplied with the X and Y blur radius values. It also accepts a value image, to control the blur radius with a mask. The values should be mapped between (0 to 1) for an optimal effect.

Properties(プロパティ)

Type(タイプ)

The difference between the types is in the way they handle sharp edges, smooth gradients and preserve the highs and the lows.

Flat (フラット)

Simply blurs everything uniformly.

Tent

Preserves the high and the lows better by making a linear falloff.

Quadratic (二次式)

Looks similar to Gaussian but can be a little faster but slightly worse looking.

Cubic

Preserve the highs, but give an almost out-of-focus blur while smoothing sharp edges.

Gaussian (ガウシアン)

Gives the best looking results but tends to be the slowest.

Fast Gaussian

An approximation of the Gaussian.

Catmull-Rom

Catmull-Rom keeps sharp contrast edges crisp.

Mitch

Preserve the highs, but give an almost out-of-focus blur while smoothing sharp edges.

Variable Size

Allows a variable blur radius, if the size input is an image.

Bokeh

The Bokeh button will force the Blur node to use a circular blur filter. This gives higher quality results, but is slower than using a normal filter.

Gamma

The Gamma button applies a gamma correction on the image before blurring it.

Relative(相対)

Percentage Value of the blur radius relative to the image size.

Aspect Correction

None, Y, X

X, Y

Values set the ellipsoid radius in numbers of pixels over which to spread the blur effect.

Extend Bounds

Allows the image, that is being blurred, to extend past its original dimension.
