Hey Andreas, I realize your email wasn't directed to me; however, since I originally posted on this topic (about a year ago), I like to throw in my two cents and say that I'm happy with your proposed solution. -Kevin -----Original Message----- From: www-svg-request@w3.org [mailto:www-svg-request@w3.org] On Behalf Of Andreas Neumann Sent: Friday, August 11, 2006 2:15 PM To: Alex Menzies; www-svg@w3.org Subject: Re: Question about getPointAtLength Hello Alex, Please apologize our late reply on this question. We discussed this issue recently and propose to return path.getPointAtLength(0) for negative values and path.getPointAtLength(path.getTotalLength()) for values that are bigger than the total path length. It is proposed that "out of range" values don't result in error reporting. One of the reasoning is that sometimes there might be accuracy issues with path length calculations from potentially different sources or algorithms. We will provide an errata for SVG 1.1 Full and include it in SVG 1.2 Full. Does that sound reasonable from an implementers point of view?
