Basic Examples  (3)

A valid image object:

Wolfram Language code: ImageQ[[image]]

A valid 3D image object:

Wolfram Language code: ImageQ[[image]]

An expression with head Image that is not a valid image object:

Wolfram Language code: ImageQ[Image[a, b]]

Properties & Relations  (1)

Testing for a valid 2D image:

Wolfram Language code: image2DQ[image_] := ImageQ[image] && Head[image] === Image;
Wolfram Language code: image2DQ /@ {[image], [image]}

Testing for a valid 3D image:

Wolfram Language code: image3DQ[image_] := ImageQ[image] && Head[image] === Image3D;
Wolfram Language code: image3DQ /@ {[image], [image]}

Possible Issues  (2)

An expression of the form Graphics[Raster[…]] is not a valid image object:

Wolfram Language code: ImageQ[\!\(\*GraphicsBox[«3»]\)]

An expression of the form Graphics3D[Raster3D[…]] is not a valid image object:

Wolfram Language code: ImageQ[[image]]
