Re: Correction to [office] Image proposals for OFFICE-4026

[Regina Henschel <regina.henschel@libreoffice.org>]

Hi all,

I have made an error in regard to fill, see comment in issue. I have 
changed the illustration accordingly. I have reduced the swing angle 
because otherwise the fill is so near to the ellipse, that it is not 
obvious, that it is a segment.

And I have attached a pptx-file with a shape, which uses the OOXML arcTo 
command.

My error was, that I had not removed the line in my examples, which I 
had added to see in which direction applications draw the arc.

ODF has no general definition of coordinate system and angle 
orientation. I had criticized the missing definitions already six years 
ago [1][2].

For the enhanced-path I think, we should be as close as possible to 
OOXML [3] and SVG. That means to use the orientation as I have drawn in 
the illustration.
