Subject: [OASIS Issue Tracker] (OFFICE-3825) How to calculate the start and end point of an elliptical arc from given angles
[ https://issues.oasis-open.org/browse/OFFICE-3825?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Regina Henschel updated OFFICE-3825: ------------------------------------ Fix Version/s: ODF-Next (was: ODF 1.3) > How to calculate the start and end point of an elliptical arc from given angles > ------------------------------------------------------------------------------- > > Key: OFFICE-3825 > URL: https://issues.oasis-open.org/browse/OFFICE-3825 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: Bug > Components: Graphics, Part 1 (Schema) > Affects Versions: ODF 1.2 > Reporter: Regina Henschel > Priority: Major > Fix For: ODF-Next > > > For a long description, example document and screenshots see mail https://www.oasis-open.org/apps/org/workgroup/office/email/archives/201304/msg00002.html > This is about commands U and T in draw:enhanced-path (19.145, part 1, ODF 1.2). The arc is defined by a start and an end angle. But the specification does not say, how to create the points. There exists two reasonable methods, which are used by applications. > (1) Intersect leg of the angle with the full ellipse. > (2) Intersect leg of the angle with the corresponding outer circle and scale the circle then to get the ellipse. > I think that the problem has to be discussed with OIC and people of the affected applications. I have no proposal. -- This message was sent by Atlassian JIRA (v7.7.2#77003)
