Filtered inline image data has no length, so its end is an EI chosen
among candidates, and the content parser chose by a different rule
than the renderer's tokenizer (hayro-syntax): the renderer also takes an
EI with no whitespace before it, and checks a candidate by reading what
follows as operators. With image data such as "7FEI 1 0 0 1 200 0 cm",
the renderer ran a cm that redaction read as image data, so text was
drawn 200 pt from where removal and its verify pass looked.
The parser now takes each inline image's end from the renderer's
tokenizer (already in the tree through pdfcraft-cos), so both read the
same operators after the image; a test runs both on the same fixtures.
Only where that tokenizer reads no image (no EI it accepts, or
parameters it can't read) does the parser fall back to its own rules,
counting the image in Parsed::ambiguous_images, and applying redactions
refuses such a page as unreadable.
The redaction interpreter started every form XObject with an empty text
state (no font, size 0, no spacing) although a form inherits its caller's
graphics state, and it ignored the /Font entry of an ExtGState set by gs.
Text shown that way was placed at the wrong positions, so removal and
the verify pass could both miss glyphs under a mark. Forms now start
from the caller's state, and gs sets the font and size as Tf does.
The engine's renderer cross-check test used the gs case as its example
of interpreter/renderer disagreement; it now runs the check directly on
an unredacted page, which also covers an input stream labelled as a
redaction overlay.
Both checks for text left under applied redaction marks (redaction's own
verify pass and the engine's renderer cross-check) skipped any page
content stream whose dictionary said /PCMark /Redaction, so that the
overlay's label would not count. An input file could put that label on
its own content stream and keep it out of both checks. Applying
redactions now records the overlay streams it adds (stamp returns the
new stream), and only those are skipped.
Pages printed as pictures were drawn with everything on them, so form fields only
printed the page content, and the document with stamps printed every comment. The
pictures are drawn from a copy holding only what the vector print draws.
A step that applies an edit logged any error and carried on, which is right
for a flatten with nothing to flatten but not for removing hidden
information or sanitizing: on a signed file the removal was refused, and the
unchanged file was written out as the action's successful result. Those
steps now fail the action unless there was nothing to remove.
Printing checked the print permission but not the separate high-quality one
(Table 22, bit 12), so a document limited to low-resolution printing came out
as its original vector pages, text included. Such a document now always
prints as pictures of at most 150 dpi, whatever the settings ask for.
Compare read both documents' words out with no check of the copying
permission, and its result, report and difference comments carry that text,
so a copy-restricted document's text could be taken out through a comparison.
Both documents must now allow copying.

* M6: renaming a field renames it in the calculations that read it
A rename silently broke every formula that used the field: a sum dropped
it, notation read it as 0 and a script kept a stale value. set_props now
rewrites the name in each field's Calculate script, in the same edit:
AFSimple_Calculate field lists, simplified field notation (the BVCALC
comment and its translation) and getField calls naming it in one string
literal. The rest of each script is kept as written; names built at run
time, non-UTF-8 script streams and a name another field still has are
left alone, and a self-check keeps a script whose meaning would change.
Notation is read by one lexer shared by notation_js, eval_notation and
the rename. form_set_props returns formulas_updated; Field Properties
says how many calculations now use the new name.

* M6: form_set_props leaves the renamed field out of formulas_updated by object
The renamed field was matched by the name given, but set_props stores it trimmed and under
its parent's prefix. When the same call changed the field's own formula, formulas_updated
listed the field as one the rename had rewritten.

* M6: calculation order: read, check, fix and set the order fields calculate in
A form's calculations run in its calculation order (/CO), which a field
joins when it gets a calculation, so a chain defined in the wrong order
shows stale values. calculation_order reads the order against the fields,
with what each formula reads (field lists, notation names, literal getField
names) and what is wrong: a field reading one that calculates later, a loop
(strongly connected components, found without recursion), a field /CO
leaves out, and /CO entries that calculate nothing. Fix order is a stable
topological sort that moves only what must move and leaves loops alone.
set_calculation_order writes /CO afresh; a name two fields share (a
malformed form) stands for the next of them in the current order.
Edit::SetCalculationOrder sets it in one undo step and recalculates, and
form_calculation_order reads, sets, moves one field or fixes the order
headlessly. An edited formula now keeps its field's place in /CO, a field
/CO lists twice calculates once, and recalculation runs each field by
object, so two fields sharing a name both calculate. The /CO code of the
Calculate tab, field scripts and recalculation goes through one place.

A bookmark made in the app always went to the top of the page. It now goes to
the top-left of the selected text, or with nothing selected to the top of the
window, as /XYZ left top null: the reader's zoom is kept, and with only the top
pinned so is the horizontal position.
- render: PageInfo::xyz_for_view, the inverse of dest_fraction. It pins only
the coordinates given; on a page turned a quarter the displayed y decides the
user left and the displayed x the user top.
- organize: add_bookmark_at and OutlineError::BadPosition (a coordinate that is
not finite is refused before anything changes).
- engine: Edit::AddBookmark takes left and top (None, None is the page top, as
before).
- automation: bookmark_add takes top and left in points from the top-left of the
displayed page, as bookmark_list reports them, bounded and refused when not a
usable number.
- ui: DocView::bookmark_position. It follows the window's vertical when the view
is turned a quarter (View > Rotate View), picks the selection's corner that
shows at the top-left, and in a spread of unequal pages uses the page that
crosses the window's top edge.
- parity: organize.bookmark-add evidence and what is still missing.
A checkmark, cross, dot or line placed on a page with /Rotate was drawn
in the page's own axes, so on a page turned 180 degrees the checkmark
came out upside down, and on a quarter turn it lay on its side.
Marks now record the page rotation (PCStampRotate, as rubber stamps do)
and their appearance is drawn upright in the displayed box and mapped
into /Rect, sharing the stamps' code for it. The mark's box is sized in
displayed axes (FillMark::rect_at), used by both the Fill & Sign tool and
fill_sign_add, so a line runs across the page as displayed.
A date the field's data picture writes as 20261018 reaches scripts as
2026-10-18, the rawValue another viewer gives them, so a script that
checks String(rawValue).length == 10 works (DA Form 31's 10b TO).
Doc comments on the functions this branch touches.
Fields keep their <format><picture>. A date display picture turns the
ISO value into its pattern for scripts' formattedValue (JavaScript and
FormCalc), so date arithmetic on formattedValue works as forms expect.
Once a script sets the value, formattedValue gives that value. Number
and text display pictures still give the raw value.
A page coloured with Edit a PDF > Background exported to Word as a
white page: export pages carried text and images only, and the Word
section has no page colour.
- pdfcraft-edit `page_background`: the colour of the first thing a
page paints, when that is an opaque fill (no soft mask, Normal blend)
in a plain gray, RGB or CMYK colour, of a path with a rectangle
covering the visible page, not clipped smaller; `None` otherwise.
- `export::Page::background` carries it; the Word writer sets it as
the document background (`w:background`, plus the
`w:displayBackgroundShape` setting Word needs to show it) when every
page shares one non-white colour. Word has one background per
document, so differing colours are left out.

While a handle of a Fill & Sign line, check, cross, dot, typed signature
or comment stamp was dragged, only the selection frame followed the
pointer; the stamp kept its old size (or place) until release. Image
signatures already had a live layer. Every stamp now gets one: the page
without the stamp, and the stamp drawn alone on a transparent page,
whose pixels are stretched with the frame. Resizing a stamp only changes
its /Rect, which its appearance is stretched to fit, so the preview is
what the release produces.
- render: RenderConfig.transparent clears the page to transparent.
- annot: isolate_annotation leaves a page showing one annotation alone.
- engine: Document::stamp_preview builds the two read-only layers; the
page beneath gets the appearances drawn for comments without one.
- ui-egui: the signature drag layer covers every stamp, rendering the
stamp's own tile sharp at the current zoom.
Review follow-up (CodeRabbit on #3475). A form edit refreshes the display
copy on every keystroke, and with /NeedAppearances that redrew every field
of the form: 68 ms per edit on a 1000-field form against 7 ms on main.
FieldAppearanceCache keeps each widget's drawing with the objects it was
drawn from: the widget and its field ancestors, the form dictionary and
the fonts of its /DR, each with the objects its entries refer to. An
entry is used only while each of them is still the same object
(Arc::ptr_eq); the document replaces an object it edits, so a changed
input is a miss, never a stale hit. The engine keeps one per editor. A
field edit on that form now takes 13 ms.
The repair note on a failed display write now names field appearances
too.

A form with /NeedAppearances true (ISO 32000-2 Table 224: the writer
"has not provided appearance streams for all visible widget
annotations") showed its text fields empty: PdfCraft only read the flag
when writing, and the display copy that draws missing appearances skips
widgets. Filled forms from tools that leave drawing to the viewer looked
blank, while Acrobat, Firefox and MuPDF show the values.
pdfcraft_forms::with_field_appearances returns a copy with text and
choice widgets drawn from their values (every one when the flag is set,
otherwise those with no /AP /N), with the generator a typed value uses.
The engine's display copy (page view, page images, Print as Image, CLI
render) applies it after the comment appearances. The document itself
is not changed, so saving writes the file as it was.
