Debilinear

Revision as of 05:13, 17 May 2014

Description

This filter is designed to reverse the effects of bilinear upsampling. Parameters and sampling pattern try to mimic Avisynth's BilinearResize.

Requirements

- AviSynth 2.5.8 or later

- Supported color formats: RGB24, RGB32, YV12

- SSE2 capable CPU

Limitations

• Sampling at 1:1 resolution is known to be unstable.
• This filter is not made for upsampling.

Syntax and Parameters

debilinear (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", bool "lsb_inout")

debilinearY (clip, int target_width, int target_height, float "src_left", float "src_top", float "src_width", float "src_height", bool "lsb_inout")

target_width int =

target_height int =

presumed 'native' resolution.

src_left float = 0

src_top float = 0

src_width float =

src_height float =

Optional crop rectangle in the input frame.

lsb_inout bool = false

16-bit input and output; uses DitherTools' Stack16 format.

• debilinearY ignores chroma planes.
