I got the impression from past discussions that pinholes would return.
_____ From: users-boun...@racket-lang.org [mailto:users-boun...@racket-lang.org] On Behalf Of Stephen Bloch Sent: Friday, June 25, 2010 11:13 AM To: PLT-Scheme Mailing List Subject: [racket] confusing graphics primitives in 2htdp/image There are a whole lot of graphics operations in 2htdp/image, and many of them come in pairs: overlay/xy and place-image, add-line and scene+line, add-curve and scene+curve, etc. that differ mainly in whether or not they crop the result to the bounding box of one of the images. (They sometimes differ in how they interpret coordinates -- whether measured from the center or the top-left of one of the images.) Since the disappearance of pinholes, the "scene" datatype doesn't serve much purpose any more. Would it make sense to use a consistent and compositional naming scheme, e.g. add-line/crop, add-curve/crop, etc? Stephen Bloch sbl...@adelphi.edu
