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

• AviSynth 2.6.0 or greater
• x64 version requires 64-bit AviSynth+ r1576 or greater
• Supported color formats: RGB32

• Microsoft Visual C++ 2015 Redistributable Package (x86 / x64)

*** 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.

Changelog

Version      Date(D/M/Y)      Changes

v0.2         04/01/2016       - Restructured so that each algorithm family has only a single function, with a scale parameter
                              - Added support for the xBRZ algorithm, including support for tweaking its parameters
                              - License changed to GPLv3 due to inclusion of the xBRZ algorithm
                              - Resource added to include file version information within the DLL
                              - Plugin is now updated for AviSynth 2.6 / AviSynth+
                              - 64-bit binaries are now included in the release (in addition to x86)
                              - Binaries are built with a newer version of MSVS (2015)
                              - Cleaned up code a bit (negligible or no effect on the binary)

v0.1         20/05/2010       - Initial release
