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

q2r or r2q(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")

clip   =

Input clip.

clip   =

background clip.

resize  string = "lanczos"

type of interpolation to be used for resizing. lanczos, bicubic, bilinear, nearest point .

ltopx  float = 0

quadrilateral left top x.

ltopy  float = 0

quadrilateral left top y .

lbotx  float = 0

quadrilateral left bottom x .

lboty  float = height - 1

quadrilateral left bottom y .

rtopx  float = frame width -1

quadrilateral right top x .

rtopy  float = 0

quadrilateral right top y .

rbotx  float = width- 1

quadrilateral right bottom x .

rboty  float = height- 1

quadrilateral right bottom y .

leftx  float = 0

Rectangle left x

rightx  float = width - 1

Rectangle right x

ytop  float = 0

Rectangle top y

rbotx  float = width- 1

Rectangle bottom y .

Examples

## This is some example code to blur  an image.
imagereader("C:\..........jpg", end = 10)
a = avisource("C;\..........avi").converttoYUY2()
converttoyv16()
# Rectangle to quadrilateral
r2q(last,last,leftx = 100,rightx = 400, ytop = 200, ybot = 480,ltopx=200,ltopy=150, rbotx = 500, rboty = 400, resize= "lanczos")
# quad to rectangle excercise
c= last

1. bg = blankclip(last,color = 0)

ScriptClip("""

h = height(bg)-1 w = width(bg)-1

   t = 0.061 *(current_frame)
   t2 = 0.127 *( current_frame)
   a = 0.501 + 0.5 * sin(t/pi)
   t1x = (-0.2*cos(t2)) * w
   t1y = (0.5-0.5*cos(t2)) * h
   t2x = (1.0+0.2*cos(t2)) * w
   t2y = (0.5-0.5*cos(t2)) * h
   t3x = (1.0+0.2*cos(t2)) * w
   t3y = (0.5+0.5*cos(t2)) * h
   t4x = (-0.2*cos(t2)) * w
   t4y = (0.5+0.5*cos(t2)) * h

   c3y = (0.5-a*sin(t)) * h
   c4x = (0.5+a*sin(t)) * w
   c4y = (0.5-a*cos(t)) * h

1. r2q(c, c,leftx=t1x,rightx=t2x,ytop=t1y,ybot=t3y,ltopx=c1x,ltopy=c1y, rtopx=c2x,rtopy=c2y, rbotx=c3x,rboty=c3y,lbotx=c4x,lboty=c4y, resize = "line")

q2r( bg,leftx=t1x,rightx=t2x,ytop=t1y,ybot=t3y,ltopx=c1x,ltopy=c1y, rtopx=c2x,rtopy=c2y, rbotx=c3x,rboty=c3y,lbotx=c4x,lboty=c4y, resize = "point" )
