# What are the differences among Graphics, Raster, Image, List(ImageData) in Mathematica in terms of Head? [closed]

I do not know the exact conceptions of Graphics,Raster,Image,List(ImageData).

I have only dealt with and used them in Mathematica.

But still, I am very confused about their exact conceptions and how they work in Mathematica and what the differences between them are. I would like to get your answers about that.

Thank you so much, for your help. :)

• Raster[] is a Graphics[] primitive, meant to be used within Graphics[]. Image[] stands on its own. – J. M. will be back soon May 31 '16 at 18:53
• @J.M. Good explanation but Rasterize?:) – yode May 31 '16 at 18:56
• @yode Rasterize returns a Graphics object containing the rasterized form of its input. It seems to me that this behavior fits well with J.M.'s comment. – MarcoB May 31 '16 at 19:31
• @MarcoB Thank you for the kind answer. :) But, what is the difference between Raster and Rasterize in terms of the type of data or head? – Smart Humanism Aug 14 '16 at 18:07
