ResizeImage:Void image:Int32, width:Float32, height:Float32

Parameter	Mode	Type	Default	Description
image	In	Int32	required	The image.
width	In	Float32	required	New width of a frame in pixels.
height	In	Float32	required	New height of a frame in pixels.

Description

Changes the size of every frame of an image to a new width and height in pixels, stretching the picture. The handle moves with the picture. Resizing again and again loses quality, so keep the original or use CopyImage first.

Differences

• The picture is stretched with smooth filtering, where the original used simple pixel picking. Edges of resized images are softer.
