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")
