Description

This is a simple filter that fills the borders of a clip, without changing the clip's dimensions. It has 6 border filling modes.

Requirements

• AviSynth+ 3.6 or later
• Supported color formats: all planar formats (8/10/12/14/16/32-bit, Y, YUV(A), and RGB(A) with or without alpha) are supported.

• Microsoft Visual C++ 2019 Redistributable Package (x86 / x64)

*** vcredist_x86.exe required for FillBorders-x86

*** vcredist_x64.exe required for FillBorders-x64

Syntax and Parameters

FillBorders (clip, int[] "left", int[] "top", int[] "right", int[] "bottom", int "mode", int "y", int "u", int "v")

FillMargins (clip, int "left", int "top", int "right", int "bottom", int "y", int "u", int "v")

clip   =

A clip to process. All planar formats are supported.

int[]  left = 0

int[]  top = 0

int[]  right = 0

int[]  bottom = 0

Number of pixels to fill on each side. These can be any non-negative numbers, within reason. If they are all 0, the input clip is simply passed through.

For FillBorders:

These must be used as named parameters. For example, `FillBorders(left=1, top=1, right=1, bottom=1)`.
If a single value for `left`/`top`/`right`/`bottom` is specified, it will be used for alpha plane and it will be right shifted by subsampling factor for chroma planes.
If two values are given then the second value will be used for the third plane and the first value will be used for alpha plane.
If three values are given then the first value will be used for alpha plane.

int  mode = 0

Mode (FillBorders only):

• 0 : "fillmargins"
  Fills the borders exactly like the AviSynth filter FillMargins, version 1.0.2.0. This mode is similar to mode 1, except that each pixel at the top and bottom borders is filled with a weighted average of its three neighbours from the previous line.
• 1 : "repeat"
  Fills the borders using the outermost line or column (aka "repeat").
• 2 : "mirror"
  Fills the borders by mirroring.
• 3 : "reflect"
  Fills the borders by reflecting (whole sample symmetric).
• 4 : "wrap"
  Fills the borders by wrapping.
• 5 : "fade"
  Fill the borders to constant value.
• 6 : "fixborders"
  A direction "aware" modification of FillMargins. It also works on all four sides.

int  y = 3

int  u = 3

int  v = 3

Planes to process.

• 1 : Return garbage.
• 2 : Copy plane.
• 3 : Process plane. Always process planes when the clip is RGB.

Note: FillMargins() is an alias for FillBorders(mode=0)

Examples

AviSource("Blah.avi")
FillBorders(left=5, top=7, right=2, bottom=0, mode=0)

#identical to: FillMargins(left=5, top=7, right=2, bottom=0)
