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)
