Word brings a document's alternative format chunks (w:altChunk) in where they
stand when it opens the file; WordCraft left them out, so a document made of
one (as generators and mail-merge tools write them) opened empty.
- docx: read_with/ReadOptions with a ChunkImporter for formats other than
WordprocessingML; nested Word documents are read here (at most 4 deep,
256 chunks and 512 MB of chunk bytes a file, XML depth counted on).
- doc: Document::adopt (moved from paste) brings another document's media,
lists, styles, notes, comments and revisions along under new ids; pictures
in groups and charts are relinked. Insert > Text from File uses it and now
keeps the file's pictures and lists.
- engine: chunks in MHT, HTML (in their charset), RTF and plain text go
through the format importers.
- formats: MHT web archives open (MIME, quoted-printable/base64, charsets,
pictures by Content-Location or cid). HTML reads style element rules
(simple selectors, cascade, budgets), paragraph margins, indents, line
height, cell widths and borders; an opened page takes Word's web-page
defaults (Times New Roman 12 pt, single lines, black headings, automatic
spacing). html::decode knows the single-byte Windows code pages.
docxide-pdf suite: croatian_regulations_altchunk goes from one empty page to
Word's 8 pages, SSIM 2.7% -> 78.7%; no other document changes.
