# Front Settings

Depending on blur type selected, different Front settings appear. The following example is the Front settings for a Gaussian or Box blur.

Width field
  Displays the width of the blur.
Height field
  Displays the height of the blur.
Proportional button
  Enable to affect the width and height proportionally.
Pixel Ratio button
  Enable to blur the image using the same proportion as its aspect ratio.
Gain field
  Displays a value by which pixel colour values are multiplied. The offset value is added to this value to determine the final colour.
Offset field
  Displays the value to add to current pixel colour values (the resulting colour value is clipped at 0).
Amount field (not shown)
  Displays the amount of radial blur.
Rotation field (not shown)
  Displays the angle of rotation for a radial blur.
Length field (not shown)
  Displays the radius amount of a directional blur.
Angle field (not shown)
  Displays the angle of a directional blur.
Bokeh Blur field (not shown)
  Displays the amount of smoothness applied to sharp bokeh edges on a defocus blur. This creates the blur that is applied to out-of-focus points of light to simulate a shallow focus.
Blooming field (not shown)
  Available for defocus blurs. Displays the gain applied to highlights in non-HDR images, to allow the creation of bokeh patterns without affecting colour integrity. This creates the glow effect that is applied to the bright spots of the image to simulate light bleeding, or blooming, over the edges.
