Blur Filters

Applies a uniform soft defocus to the entire image.

• -Radius — the blur strength in pixels. Higher = more blur. Practical range: 0 to 200px.
• -Quality — Low, Medium, or High. Higher quality reduces banding artifacts in the blur but increases computation time.

Applies blur in a single linear direction, simulating motion along that axis.

• -Angle — the direction of blur (0 degrees = horizontal)
• -Distance — how far the blur extends along the angle direction (in pixels)

Applies blur rotating around a center point. Simulates a spinning or rotating subject.

• -Center X / Y — the pivot point of the rotation blur
• -Strength — how much the blur rotates (expressed in degrees)

Applies blur radiating outward from a center point, simulating a fast zoom movement.

• -Center X / Y — the origin point of the zoom
• -Strength — how far the blur extends radially (as a percentage of image size)

Simulates shallow depth of field — sharp in one region, blurred toward the edges. Two modes:

• -Linear — a horizontal band is sharp; blur increases above and below (classic tilt-shift miniature effect)
• -Radial — a circular region is sharp; blur increases toward the edges (simulating a large-aperture lens)

Parameters:

• -Focus Position — where the sharp zone is centered
• -Focus Width — how wide the sharp zone is
• -Max Blur — the maximum blur applied at the fully blurred regions
• -Falloff — how gradually the blur transitions between sharp and blurred (linear, quadratic, or smooth)
