TFormFilter:Void enable:Int32

Parameter	Mode	Type	Default	Description
enable	In	Int32	required	True for smooth results (the default), False for the nearest pixel.

Description

Chooses how TFormImage, ScaleImage and RotateImage look pixels up. With the filter on, the colors of neighboring pixels are blended for a smooth result. With it off, the nearest pixel is taken, which keeps hard edges and is the right choice for pixel art.
