Description

Reform uses matrix algebra for transformations. Reform has two modes viz: rectangle to quadrilateral and quadrilateral to rectangle. Lanczos or cubic or linear or nearest point interpolation methods can be opted. Full Description


Requirements

  • AviSynth+ r2347 or later

Syntax and Parameters

Reform (clip, clip, string "resize", float "ltopx", float "ltopy", float "lbotx", float "lboty", float "rtopx", float "rtopy", float "rbotx", float "rboty", float "leftx", float "rightx", float "ytop", float "ybot", bool "qr", bool "norm")


clip   =
Clip to be skewed into quadrilateral or deskewed into rectangle


clip   =
Clip to be used as background


string  resize = "cubic"
Radius of grid to use
  • "lanczos"
  • "cubic"
  • "line"
  • "point"


float  ltopx = 0
Q left top x coordinate


float  ltopy = 0
Q left top y coordinate


float  lbotx = 0
Q left bottom x coordinate


float  lboty = frame height - 1
Q left bottom y coordinate


float  rtopx = frame width - 1
Q right top x coordinate


float  rtopy = 0
Q right top y coordinate


float  rbotx = frame width - 1
Q right bottom x coordinate


float  rboty = frame height - 1
Q right bottom y coordinate


float  leftx = 0
R left x coordinate


float  rightx = frame width - 1
R right x coordinate


float  ytop = 0
R top y coordinate


float  ybot = frame height - 1
R bottom y coordinate


bool  qr = true
R bottom y coordinate
  • true = q to r
  • false = r to q


bool  norm = false
Whether normalised coordinates are specified?
  • true = normalized
  • false = real


Examples

Script example: 

ColorBars().ConvertToRGB32()
bg = blankclip(last)
Reform(bg, resize= "lanczos",leftx = 100,rightx = 400, ytop = 200, ybot = 480,ltopx=200,ltopy=150, rbotx = 500, rboty = 400)
