Description

PointSize is a collection of specialized resizers for pixel-art and other low resolution graphics (e.g. old or portable video game captures). For an explanation of the various filters, please see: http://en.wikipedia.org/wiki/Image_scaling

Requirements


*** vc_redist.x86.exe is required for PointSize_x86
*** vc_redist.x64.exe is required for PointSize_x64


Syntax and Parameters

LQx (clip, int "scale")
HQx (clip, int "scale")
scalex (clip, int "scale")
xBRZ (clip, int "scale", float "Yweight", float "EqColorTol", float "DomDirThresh", float "SteepDirThresh")


clip   =
Input clip


int  scale = 2
Supported "scale" values for various filters (inclusive):
  • scalex(): 2 to 3
  • LQx(): 2 to 4
  • HQx(): 2 to 4
  • xBRZ(): 2 to 6


float  Yweight = 1
float  EqColorTol = 30
float  DomDirThresh = 3.6
float  SteepDirThresh = 2.2
Additional parameters for xBRZ:
  • Yweight: luminance weight
  • EqColorTol: equal color tolerance
  • DomDirThresh : dominant direction threshold
  • SteepDirThresh : steep/shallow direction threshold
luminanceWeight, equalColorTolerance, dominantDirectionThreshold, and steepDirectionThreshold parameters for xBRZ.
