Subject: [OASIS Issue Tracker] (OFFICE-4030) Bottom to top, left to right writing direction
[ https://issues.oasis-open.org/browse/OFFICE-4030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=82729#comment-82729 ] Regina Henschel commented on OFFICE-4030: ----------------------------------------- >> If the attribute value is page each part of the section uses the layout direction of the page on which this part appears. >... but only if it actually applies - the section could be in a table or frame with its own writing-mode... well okay not frame because those don't split, but table cells may split. Ah, you are right. I was not aware, that it is possible to use a section inside a cell. Â >> How are the table margins applied in case the writing mode of the table is orthogonal to the writing mode of the page? That is common in Chinese vertical texts. > i can't figure out how to do this - is there any application where this can be done at the moment? I don't know whether any application can do that. I have only seen such layout on [https://www.w3.org/TR/2020/NOTE-jlreq-20200811/#an_example_of_layout_with_a_table.] I was not able to generate such layout in LibreOffice other than putting the table into a frame. > Bottom to top, left to right writing direction > ---------------------------------------------- > > Key: OFFICE-4030 > URL: https://issues.oasis-open.org/browse/OFFICE-4030 > Project: OASIS Open Document Format for Office Applications (OpenDocument) TC > Issue Type: New Feature > Components: Paragraph > Reporter: Andras Timar > Assignee: Patrick Durusau > Priority: Minor > Fix For: ODF 1.4 > > Attachments: Comparison standards and implementations.odt, Proposal_writing-mode_Version_TC2.odt, Proposal_writing-mode_Version_TC3.odt, Proposal_writing-mode_Version_TC4.odt, Proposal_writing-mode_Version_TC5.odt, Proposal_writing-mode_Version_TC6.odt, overview.ods > > > h1. Summary > Proposal owner: Miklos Vajna > Proposal short name: Bottom to top, left to right writing direction > h1. Rationale > *Use cases:* > Users sometimes want to have a text direction which is similar to latin text > (left to right, then top to bottom), but rotated 90 degrees counter-clockwise. > Also, this improves consistency, as doing the same in the clockwise direction > is already possible (the top to bottom, right to left direction is used for > e.g. Japanese text). > *Alternatives considered:* > It is possible to rotate characters at a span level, but that only gives > similar result as long as the content fits a single line. > h1. Requested changes to the ODF Standard > Text changes/additions (compared to ODF 1.2): > 20.394.2 <style:graphic-properties> (existing section) > Append to the end of style:writing-mode attribute value list: bt-lr. > 20.394.3 <style:page-layout-properties> (existing section) > Append to the end of style:writing-mode attribute value list: bt-lr. > 20.394.4 <style:paragraph-properties> (existing section) > Append to the end of style:writing-mode attribute value list: bt-lr. > 20.394.5 <style:section-properties> (existing section) > Append to the end of style:writing-mode attribute value list: bt-lr. > 20.394.6 <style:table-cell-properties> (existing section) > Append to the end of style:writing-mode attribute value list: bt-lr. > 20.394.7 <style:table-properties> (existing section) > Append to the end of style:writing-mode attribute value list: bt-lr. > Schema changes/additions: > {{<rng:define name="common-writing-mode-attlist">}} > {{Â <rng:optional>}} > {{Â Â <rng:attribute name="style:writing-mode">}} > {{Â Â Â <rng:choice>}} > {{Â Â Â ÂÂ<rng:value>lr-tb</rng:value>}} > {{Â Â Â ÂÂ<rng:value>rl-tb</rng:value>}} > {{Â Â Â ÂÂ<rng:value>tb-rl</rng:value>}} > {{Â Â Â ÂÂ<rng:value>tb-lr</rng:value>}} > {{Â Â Â ÂÂ<rng:value>lr</rng:value>}} > {{Â Â Â ÂÂ<rng:value>rl</rng:value>}} > {{Â Â Â ÂÂ<rng:value>tb</rng:value>}} > {{Â Â Â ÂÂ<rng:value>page</rng:value>}} > {{Â Â Â ÂÂ<rng:value>bt-lr</rng:value>}} > {{Â Â Â </rng:choice>}} > {{Â Â </rng:attribute>}} > {{Â </rng:optional>}} > {{</rng:define>}} > In other words, allow bt-lr as a new value of the style:writing-mode > attribute. > h1. Impacts > *Conformance:* > This proposal will not add any mandatory features or behaviors. > *Backwards compatibility:* > This change will not impact existing ODF processors, the usage of the new > attribute value is optional. > *Accessibility impact:* > This change will not impact accessibility. > *Interoperability:* > OOXML's wordprocessingML has a <w:textDirection w:val="btLr"/> markup to > describe the same, this proposal allows roundtripping that feature in ODF. > LibreOffice 6.3 implements this layout feature in its ODF extension namespace. -- This message was sent by Atlassian Jira (v8.3.3#803004)
