With repeated names numbered when a brush library is read, a stroke that
names a repeated brush draws the first brush of that name, and a later
brush of the name is read as "Name 2". Three tests built a library with a
repeated name and expected the later brush:
- Document Info lists a name two stored brushes share with the first
brush's type (art), not the last one's.
- The two render memory tests add their own `Dots` scatter brush beside
the default library's `Dots`. They now remove the default `Dots` first,
so the stroke draws their brush.
- The .ai writer test that leaves out a Pattern brush "X" gets the
Calligraphic brush after it back as "X 2", the name it had in the
document.
With the selection as its scope, a fix that removes or unwraps objects
(Needless Groups, Stray Points, Empty Text and the others) kept the list
of selected objects current by searching it and splicing it once for each
object it changed. Removing many selected objects above a long run of
others took time that grew with the square of their number.
The list is now rebuilt in one walk after each pass: each changed object
gives way to what replaces it, in its place, and the others keep their
order. The objects found, the counts, the document and the undo step are
the same as before.
Empty Artboards deleted each empty artboard with its own Vec::remove and
walked every ruler guide again for each one. It now drops the empty
artboards in one walk and deletes their guides in one more. The same
artboards and guides are deleted as before.
Tests cover the order after unwrapping nested and empty groups, Fix All
reaching an unwrapped member on a later round, the rebuild itself, the
number of objects looked at for 150 and 300 removals, and the number of
walks over the artboards and guides when 40 empty artboards are deleted.
stops and stop flattened the path twice, once for the points and once
for its length, and stop did both before rejecting an index past the
last object. place validated the path with attachable_path first, and
transform measured the old and new paths up to three times each.
A private Measured value now holds the flattened first subpath with its
length and closed flag, and path_length, stops, stop and transform use
it. stop returns None for an out-of-range index without measuring, and
a move of the group measures no path.
attachable_path now uses path_length, so a path whose length overflows
to infinity is no longer offered as one objects can attach to when
placement cannot measure it.
A Smooth drag along the middle of a curved segment smoothed nothing when
neither of the segment's anchors was within the reach, and paths of two
anchors were never smoothed.
- path.smoothRegion searches each curved segment where it can come
within the reach, halving it down to pieces no longer than half the
reach, and adds an anchor in the middle of each stretch in reach; the
existing reach split then cuts the segment where the drag enters and
leaves the reach. A drag that only grazes a curve finds the place on
it nearest the drag. The search is bounded per drag and shared
equally by the segments in reach.
- Paths of two anchors are smoothed, open or closed.
- Alt with the Paintbrush smooths a selected two-anchor curve; a
two-anchor straight line still gets the closed stroke. Both sides use
one segment_is_straight test.
Part of #2224
While the Smooth tool drags with a path selected that it can smooth, a
dashed outline shows the band its release smooths: every point within
the tool's radius (12 screen pixels) of the drag, round at both ends.
Alt smoothing with the Pencil, Paintbrush and Blob Brush shows the same
band. A selection with no path the tool can change shows none.
- The band is kept in squares eight radii wide, and each step of the
drag adds its area only to the squares it reaches. A piece of a
square's outline along a side is left out only where the square
across holds band area.
- A drag segment too long for the squares (a jump drawn zoomed out and
viewed zoomed in) keeps its band near each end in the squares and
shows the rest as the two sides of its band. A step that cannot be
added whole is added one segment at a time.
- A coarser grid of cells lists the squares and long segments, so a new
one is checked only against those near it, and an outline is made
again only where the band near it changed.
- After a zoom change mid-drag the band is outlined again a few hundred
points per frame, and the work on long segments stops for the frame
after a fixed budget. Tools report unfinished overlays with
Tool::overlays_pending, and the canvas then draws again on the next
frame, so the band covers the whole drag even while the pointer holds
still.
In SVG and PDF output, each piece of a warped image whose pieces can show
through was drawn through a mask of every later piece that reaches it. On a
later piece's antialiased edge the viewer multiplies the earlier piece's
coverage by the mask and draws the later piece over it, so an image with
both opaque and partly transparent pixels came out lighter at its opaque
pixels along the triangles' edges (alpha 184 of 255 in the new SVG test).
A later piece now goes into an earlier piece's mask only when a pixel of
either piece's image within 2 pixels of their overlap is less than opaque
(vectorcraft_effects::WarpSeams). Where two pieces overlap over opaque
pixels, the later one is drawn over the earlier one without a mask.
A threaded story measured each type-on-a-path frame, and each area frame
whose lines align to the center, the bottom or justify vertically, with
the whole rest of the story. A story of 1,500 one-line paragraphs through
40 such frames was laid out over about 2.1 million bytes while the frames
were measured.
- Area type without Shrink Text to Fit now takes the paragraph probe for
every vertical alignment. A reflow pass that places less text is
undone, so when the final layout stops before the last paragraph break
measured, every pass placed the same lines as with the whole rest.
- Type on a path takes it when its line starts at the start bracket: no
Dynamic Text, Optical Margin Alignment or Roman Hanging Punctuation,
the first paragraph aligned Left, Justify Left or Auto, and vertical
type or no right-to-left text in the rest of the story. The story is
scanned for right-to-left text once per distribution.
- Shrink Text to Fit, the other path settings and a share that ends in
the story's last paragraph are still measured with the whole rest.
The same 40 frames are now measured over 21,035 bytes (aligned to the
center) and 20,583 bytes (paths aligned Left). Each frame's share is
unchanged: the tests compare every slice with the whole-rest result for
both distribution entry points, across alignments, frame shapes, wraps,
path settings, right-to-left text, styles, lists and seeded stories.
The Hindi catalog called a variable चर, परिवर्तनीय, वैरिएबल or
वेरिएबल from one row to the next: the Variables panel, Load and Save
Variable Library, Variable Options and the data-merge messages mixed
them, and so did variable widths, the font technology label and
environment variables. Every such row now says वेरिएबल (plural
वेरिएबल्स).
Close or Join, Join Point Text, Join the lines of each paragraph and
most of the path join messages said शामिल हों, which means joining a
group; the other join messages used जुड़ना, जॉइन or the English word.
They now say जोड़ें, as the Join command already did. The Discord rows
keep शामिल हों, and the stroke corner names and the Join tool keep
जॉइन.
hindi_rows_use_one_term_for_a_variable_and_for_joining_paths checks
both terms in every row. docs/localization-hi.md lists the terms, and
the Hindi row counts in it and in docs/localization-parity.md are
current (8,782 rows, 3,014 @msg).
