Returns the distance from the top of the image to its baseline.
The baseline of an image is the place where the bottoms any letters line up,
but without counting the descenders, e.g. the tail on ``y'' or ``g'' or ``j''.
Unless the image was constructed with @racket[text], @racket[text/font]
or, in some cases, @racket[crop], this will be the same as its height.

The baseline of an image is the place where the bottoms any letters line up, not counting descenders, e.g. the tail on ``y'' or ``g'' or ``j''.
Using @racket["pinhole"] or @racket['pinhole] is only allowed when all of the image arguments have @seclink["pinholes"]{pinholes}.
See also @racket[image-baseline] for more discussion of baselines.
