Description

z.lib resizers for AviSynth+

Requirements

• AviSynth+ x86/x64
• Supported color formats: RGB24, RGB32, Y8, YV12, YV16, YV24 (all 8...16 bit and float colorspaces)

Syntax and Parameters

z_ConvertFormat

Scaling, colorspace conversion, and depth conversion.

z_ConvertFormat (clip clip, int "width", int "height", str "pixel_type", str "colorspace_op", str "chromaloc_op", bool "interlaced", float "src_left", float "src_top", float "src_width", float "src_height", str "resample_filter", float "filter_param_a", float "filter_param_b", str "resample_filter_uv", float "filter_param_a_uv", float "filter_param_b_uv", str "dither_type")

clip   =

Input clip.

int  width =

int  height =

Output width and height in pixels.

string  pixel_type =

Output pixel type ("YV12", "YUV420P16", etc.)

string  colorspace_op =

Colorspace operation description.

Format is "matS[:transS[:primS[:rangeS]]]=>matD[:transD[:primD[:rangeD]]]"

Example JPEG to MPEG: "170m:709:709:f=>709:709:709:l"

string  colorspace_op =

Chroma location operation description.

Format is "[locS]=>[locD]"

Example JPEG to MPEG2: "center=>left"

bool  interlaced = false

• debicubicY ignores chroma planes.

float  src_left =

float  src_top =

float  src_width =

float  src_height =

Optional crop rectangle in the input frame.

string  resample_filter =

Resampling modes: "point", "bilinear", "bicubic", "spline16", "spline36", "lanczos"

Compatibility aliases: "gauss", "spline64", "lanczos4","blackman", "sinc"

float  filter_param_a =

float  filter_param_b =

First and second parameter to resampler.

Example Bicubic (Mitchell-Netravali): resample_filter="bicubic", filter_param_a=0.333, filter_param_b=0.333

Example 4-tap Lanczos: resample_filter="lanczos", filter_param_a=4

string  resample_filter_uv =

Resampling mode for chroma.

float  filter_param_a_uv =

float  filter_param_b_uv =

First and second parameter to chroma resampler.

string  resample_filter =

Dithering type: "none", "ordered", "random", "error_diffusion"
