LibreOffice 7.5 እርዳታ
Creates a universal accessibility-complying PDF file that follows the requirements of PDF/UA (ISO 14289) specifications.
The specification defines the required structure and formatting of a document and PDF features that are better suited for accessibility. This specification can also be used to produce documents that achieve W3C's Web Content Accessibility Guidelines 2.0 (WCAG 2.0).
The present implementation (January 2020) checks the following:
The document title is set.
The document language is set, or all styles in use have the language property set.
All images, graphics, OLE objects have an alternate (alt) text or a title.
Tables do not contain split or merged cells.
Only integrated numbering is used, no manual numbering. For example, do not type "1.", "2.", "3." at the beginning of paragraphs.
Hyperlink texts without the underlying hyperlinks.
The contrast between text and the background meets the WCAG specification.
No blinking text.
No footnotes or endnotes.
Headings must increase sequentially with no skips, for example, you cannot have Heading 1, Heading 3, and no Heading 2.
Text does not convey additional meaning with (direct) formatting.
