When I reviewed the text for this change, I noticed that that we’ve switched “height” and “width” in the prose for the cx ( “count of x” ) example. It appears that we’ve made a similar mistake in the prose for the cy example, too. Clearly these are simple editorial changes we should make.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Stepping back, I believe that the ideal wording would be to refer to “extents” as “lengths along the {x,y}-axis” as opposed to heights, widths and lengths. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>That said, I don’t believe these minor changes impact interoperability or an implementers ability to implement the standard. I find that readers reasonably skilled in graphics ( the scope of this issue ) understand that within the scope of extents, cx is always the count along the x-axis and cy is always the count along the y-axis. The notions of height, width and length are more for the unskilled reader. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If WG4 believes we need to change the text, I’d suggest that we limit the changes to the prose and not change the names of the elements [ e.g., don’t change “cy (Extent Width)” to “cy ( Extent Length along the y-axis )” ]. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Let’s get guidance during today’s teleconference.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>shawn<o:p></o:p></p></div></body></html>
