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

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.

I am puzzled that the angle are clockwise and y downwards. Where in ODF do I find this specified?

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.

[1] OFFICE-3775 and https://lists.oasis-open.org/archives/office-comment/201208/msg00003.html [2] OFFICE-3825 and https://www.oasis-open.org/apps/org/workgroup/office/email/archives/201304/msg00002.html [3] Illustration in chapter (page 2902) and (page 2888) in ISO/IEC 29500-1:2016

Otherwise, I like the second picture best.

Kind regards
