			== Description ==
			Reform plugin does a geometric transformation and in certain cases may produce artifacts. [[Reformer]] Plugin which does Matrix operations gives better results and if possible switch to that plugin.

			This plugin is meant for correcting minor distortions. If used for very large distortions most likely the linearity assumptions and interpolation quality will suffer. Artifacts may appear especially in case of deskew function.

			There are 2 functions included in this plugin. These are:

			*<code>Deskew</code>: Converts a quadrilateral to a rectangle.

			*<code>Skew</code>: Converts a rectangle to a quadrilateral.

			Most of the parameters can be linearly varied over the length of the effect, and so it can be used to distort or correct distorted faces or objects progressively. The parameters for both these functions are identical. For reading coordinates correctly the plugin [[Grid]] can be used. Interpolation options are Lanczos 6x6, cubic 4x4, linear 2x2 and nearest point It has to be ensured that the quadrilateral is convex


			* See official documentation: http://www.avisynth.nl/users/vcmohan/Reform/Reform.html

			* [x86]: [[AviSynth+]] or [https://sourceforge.net/projects/avisynth2/ AviSynth 2.6]
