A tab is at most 260 px wide. A longer document name ends in an ellipsis
(cut at a grapheme boundary, RTL names included), the dirty marker and
zoom stay readable, and the full name shows in the tab's tooltip. Tabs
and their close buttons carry accessible labels.
Fixes#603
object.swapFillStroke and object.defaultFillStroke change every unlocked
target in one edit, so one undo restores them all. Swap works per object
and keeps each object's tints; a stroke that gets a colour at zero weight
gets the default 1 pt. Objects that are locked, or on a locked layer,
stay as they are. color.swapFillStroke and color.defaultFillStroke run
these commands.
The proxy's tooltips named keys that did nothing. color.defaultFillStroke
(D), color.swapFillStroke (Shift+X), color.toggleFillStroke (X) and
color.applyNone (/) are UI commands; the proxy's buttons run the same
commands. Swap keeps the fill and stroke tints.
Which of fill and stroke is in front lives in UiState, shared by the
Tools panel proxy, the Color panel and the commands. The single-key
shortcuts stay out of text being typed, like the tool shortcuts.
text_line flipped glyph outlines that the font database already gives
y-down, so each family's preview in the font menu was drawn upside down
below its baseline and cut off at the bottom of the image.
IDML names some languages by locale code
(AppliedLanguage="$ID/de_DE_2006", "$ID/nl_NL_2005") beside names such
as "English: USA" and "Spanish: Castilian". language_tag maps any locale
code (ll, ll_CC, ll-CC, with a reform year after them) to its BCP 47 tag
(de-DE, nl-NL; kept once per process, at most 512 distinct tags), ignores
IDML's $ID/ prefix, and knows Spanish: Castilian (es-ES) and Swiss French
and Italian. The stored name stays as written, so IDML round trips are
unchanged.
What depends on the language now goes by the tag: typographer's quotes
(by language subtag; Swiss regions take guillemets), English
hyphenation and spelling (is_english), Korean word breaking and the CJK
fallback chains (ja-JP, ko-KR are Japanese and Korean whatever the
region).
Font menus list Western (and other-script) families first, then
Japanese, Simplified Chinese, Traditional Chinese and Korean families,
each group alphabetical by the name shown, with a separator between
groups. The group comes from the font's own data, strongest signal
first: the meta table's dlng (else slng) languages, family names in a
CJK language (Windows and Macintosh language IDs), OS/2 code pages (JIS,
Chinese Simplified, Korean Wansung, Chinese Traditional, Korean Johab);
a font declaring none of these goes by what it covers (kana, Hangul,
ideographs). Ties go Japanese, Simplified, Traditional, Korean. Loaded faces are classified
once; installed fonts by the font scan, which also reads their OS/2 and
meta tables (and cmap only for fonts declaring nothing), capped.
CJK families show their family name in their language, the English
name on hover; Preferences > Type > Show Font Names in English
(prefs.set {showFontNamesInEnglish}, off by default) shows English
names. Search matches either name; documents store the English name.
The Character panel, Control bar, Properties, style dialogs, Find Font
and Glyphs panel lists all follow this order. The main font menu stays
open while searching or starring (it closed on any click inside).
Font previews don't draw DesignCraft's missing-glyph box for fonts
whose .notdef is empty.
A character the applied font lacks is drawn as that font's missing-glyph
box (its .notdef, gid 0), on screen and in PDF, and Preflight lists the
characters by font ("Missing glyphs in <family> <style>: …", an error,
at most 20 named). A .notdef without an outline is drawn as a hollow box
across its advance, so a missing character never disappears. PDF draws
.notdef glyphs as paths, which PDF/A and PDF/UA accept. Kenten marks are
set in their text's font the same way.
The document setting Draw Missing Glyphs from Fallback Fonts
(DocSettings::glyph_fallback; Preferences > Composition,
document.preferences {glyphFallback}, undoable) draws them from fallback
fonts instead (the language-aware chains, then any font; kenten marks
from a fallback font, else a bullet). It is off in new documents and
IDML imports and on in files saved before it existed, which keep
drawing as they did. A missing font's substitute always uses fallback
fonts. The composition cache's signature includes the setting. Tests
whose Arabic comes from a fallback font turn the setting on.
language_tag ignores case and punctuation and recognises Chinese in its
common spellings and locale codes (Simplified Chinese, Chinese
(Simplified), zh_CN, zh-Hans; Traditional Chinese, zh_TW, zh_HK,
zh-Hant), and Japanese and Korean locale codes (ja_JP, ko_KR).
Typographer's quotes for Chinese and Japanese follow the tag, so every
spelling takes the same quotes. IDML import keeps the name as written.
Composition draws the characters a named font lacks with fallback faces
(the language's CJK chain, then the generic fallbacks). Package now also
copies their font files: it collects the distinct faces of the visible
glyphs of every composed story (table cells and footnotes included) and
copies those that aren't a named font's face by the same rules (restricted
licence listed, bundled included with DesignCraft, no file noted, each file
once). The report lists them under Fallback fonts.
The fonts in a document's Document Fonts folder are registered under a
font scope that the document holds while it is open (Document::font_scope,
runtime only; DocState keeps the scope alive and closes it when the last
copy of the state goes: file.close, closing a tab, revert, a book
chapter's export, the session ending). Composition, preflight, font.list,
Package and the font menus, Glyphs panel and previews look fonts up
through FontDb::scoped(scope): the document's own faces first, then the
shared ones. Other open documents don't see them, and two documents with
fonts of the same name each set text in their own. Composite fonts'
member fonts and the fallback for kenten marks are looked up the same
way.
Font files stay in memory for the session (FaceRef keeps faces for the
process); a document opened again reuses the faces of its unchanged files
(same path, length and modification time) instead of reading them again.
The composition cache's signature includes the scope; the word cache and
the outline and PDF font caches are keyed by face. Variable font
instances are kept per base face.
A family's installed faces join the shared fonts all at once, and a
face two lookups load at the same time is kept once, so a parallel
fallback lookup never takes a family's bold before its regular has
loaded.
In vertical text Down and Up move along the line by a character (by a
word with Alt), Left and Right to the next and previous line keeping the
position along it, and Shift extends, as the arrows do in horizontal
text turned a quarter. The caret is a bar across the vertical line.
Vertical is a story property: every frame of a thread is vertical or
horizontal together, a frame threaded onto a story takes its direction,
and frames split off by threading or breaking a thread keep theirs.
Type > Story Direction is type.storyDirection {vertical} (checked in the
menu) for the stories of the text selection or selected frames;
object.textFrameOptions {vertical} and frame.create {vertical} set the
frames' stories. Documents that stored Vertical on the frame open with
each story taking its first frame's direction. IDML StoryOrientation is
read into and written from the story, beside its column direction
(StoryDirection), which stays a separate setting.
In vertical frames upright runs are shaped TopToBottom (vert; vkrn/vpal
when asked), advance by their vertical metrics and hang from their
vertical origins on the em box centre, on screen and in PDF; their line
ascent and descent are the em box. Turned runs stay horizontal without
vrt2 (rather than every run taking vert and vrt2), and tate-chu-yoko
stays horizontal and centres on the em box, its offsets moving it along
and across the line. Horizontal Kana in upright runs takes vkna. Each
run is shaped with the text around it, as horizontal runs are.
FontFace::v_advance, v_origin and em_box read vmtx/vhea, VORG (else the
glyph top plus its top side bearing) and the ideographic em box (BASE
ideo/idtp, else OS/2 typo metrics, else ascender/descender, centred on one
em); fonts without them fall back to the em box. shape_vertical shapes
top to bottom with those metrics (vert, and vkrn/vpal when asked).
Korean is set word by word (KLREQ): Hangul, in any language, and Han
ideographs in Korean-language text take no line breaks between
characters, so lines break at spaces. Glyphs carry their language tag
for this. A paragraph attribute, koreanCharBreaks (type.para, paragraph
styles, Paragraph Style Options > Justification), breaks between
syllables instead. It is DesignCraft-only; IDML doesn't carry it.
A paragraph's kinsoku set decides which breaks it forbids, and Korean
still breaks at spaces under one.
Kinsoku still holds, also when the single-line composer has to split a
word wider than the measure: the split moves back so no line starts
with closing punctuation.
Opening a .designcraft or .idml file from disk (file.open, file.openIdml,
book chapters, recovered documents) loads the fonts in the "Document
Fonts" folder beside it. Their faces come before installed faces of the
same family and style. The files are untrusted: at most 200 are read,
256 MB each (full CJK collections fit) and 512 MB in all; files over a
limit by their listed length are skipped unread, and damaged, oversized
and surplus files are listed in the open result's warnings. Document fonts stay
loaded for the session (the font database is process-wide).
Faces record their source (bundled, installed file, document file,
memory); font.list reports it. File > Package copies the font files the
document uses into the package's Document Fonts folder unless OS/2
fsType restricts the licence, and the report says which fonts weren't
copied and why.
Characters the primary font lacks try a fallback chain by language
before the language-blind search: Japanese (the craft-fonts Japanese
faces first, Mincho first), Simplified Chinese (also plain Chinese),
Traditional Chinese and Korean each list their macOS, Windows and Linux
system families. Hangul, kana and Bopomofo pick their language's chain
whatever the character language; ideographs and CJK punctuation follow
it, and keep today's fallback without a CJK language. Chain families
load from the system font catalog the first time they are needed.
designcraft_fonts::testing (feature `testing`) builds synthetic fonts
with a given family name and coverage for tests.
The character's language (as IDML names it) maps to a BCP 47 tag
(designcraft_doc::language_tag) and is the shaping context's language
on the harfrust buffer, so OpenType locl applies for every language in
the list (Japanese, Chinese, Korean, Turkish, ...), not only Arabic,
Persian, Urdu, Hebrew and English: other names used to reach the
shaper as they were written, which it doesn't know, so their locl never
applied. designcraft_fonts no longer maps names itself. The word-shaping
cache is keyed by the tag. Chinese: Simplified and Chinese: Traditional
join the language list (plain Chinese stays, tagged zh); Simplified
Chinese takes curly quotes, Traditional Chinese corner brackets.
Phased plan for professional CJK typesetting (the East Asian feature set):
sources (JLREQ, CLREQ, KLREQ, JIS X 4051, OpenType, IDML), current state
and known bugs, architecture (character classes, mojikumi, kinsoku and the
Japanese composer, vertical metrics, annotations, grids, composite fonts),
IDML attributes, phases with estimates and open decisions. It builds on
the CJK composition of docs/cjk-typography.md (composite fonts, kinsoku
sets, aki, tsume, jidori, hanging punctuation, em alignment and leading
models, kenten characters, tate-chu-yoko offsets) and plans what remains.
Scale: a small square grown into a larger one from their shared corner,
with a diagonal arrow. Shear: a rectangle slanted into a parallelogram
along its base, with an arrow. Both are drawn in code in the icon set's
stroke weight; Free Transform keeps its drawing.
A parameter written as `key (description)` was dropped by the command
form parser, so Object › Transform › Rotate… and Shear… (and Basic
Feather) had no required field, opened no dialog and ran with defaults.
The key is now the leading word and the parenthetical becomes its hint.
Double-clicking the Selection, Rotate, Scale or Shear tool opens Move,
Rotate, Scale or Shear.
Decode the merged composite of .psd/.psb files in designcraft-images
(public file format spec) instead of the psd crate, which mapped
channels by count: grayscale with extra alpha/spot channels rendered
yellow, blue or invisible, and RGB + one spot channel was read as RGBA.
Channels now map by colour mode (Bitmap, Grayscale, Duotone, Indexed,
RGB, CMYK via the uncalibrated CMYK formula, Lab; 8 and 16 bit; raw and
PackBits). The first extra channel is the alpha only when the layer
count is negative (also via Lr16/Lr32), un-matted from white; other
extra channels are ignored. Damaged or oversized files return None
without panicking. Drops the psd dependency and its panic paths.
