<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "> 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?<br><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div>Stephen Bloch</div><div><a href="mailto:sbloch@adelphi.edu">sbloch@adelphi.edu</a></div><div><br class="webkit-block-placeholder"></div></span><br class="Apple-interchange-newline"> </div><br></body></html>
