PdfCraft's bootstrap renderer draws byte-aligned Group 3 whose fill ends
each end-of-line code on a byte (as TIFF writes it) as other rows than
decode_ccitt reads (black box, at every /K, with /EndOfLine or not:
mostly the first row, then blank). Redaction cleared pixels in the
picture decode_ccitt reads, so a mark over what PdfCraft showed needn't
cover what was cleared, and content shown blank stayed in the copy. Such
an image (/K 0 or more, /EncodedByteAlign) is now removed whole, as
every CCITT image was before this PR; Group 3 off bytes and Group 4 are
still cleared.
The image's parameters come from Document::fax_params, the reading of a
fax image's /DecodeParms entry that decoded_image already did, now on
its own (it was to come with #4404, which uses it too). The redaction
README, the module doc, the redaction and core.image-filters notes and
the spec parity table's status line and revision row say so, and the
core.image-filters note now records the renderer's misdrawing.
group_3_on_bytes_is_removed_whole_and_other_fax_images_cleared: a white
16 × 2 picture, checked to decode as such, is removed whole on bytes (no
codes; codes at /K 0; at /K 1 with /EncodedByteAlign by reference) and
cleared off bytes and as Group 4 on bytes. It fails without the guard;
cargo-mutants catches every viable mutant of it.

decode_ccitt reads byte-aligned Group 3 whose data has end-of-line codes
but none before the first row (not as T.4 sends them) on bytes. At /K 0
with the fill ending each code on a byte, about one small picture in
five is then read as other rows; at fax width almost none are, as such
pages come out short and are refused. Export already said so. The
optimizer, when it resamples such an image or stores it again as Group 4
from behind another filter, and redaction, when it clears pixels in one,
write those rows back, and nothing said that.
Black-box, PdfCraft's renderer draws such an image exactly as
decode_ccitt reads it (all 42 misread of 200 seeded pictures, behind
ASCII85Decode too), so the written image is what PdfCraft showed before.
Refusing such data instead (a code after nearly every row but none
first) would also refuse some ordinary Modified Huffman images, whose
rows can meet 11 zeros by chance (0.5 to 5% of small ones in a
black-box probe), so the limit is stated rather than guarded: in
decode_ccitt's doc, the filters, optimize and redact READMEs, and the
core.image-filters and mono-compression notes. The optimize README's and
the mono-compression note's "not yet: Group 3 to Group 4 without
resampling" now say a lone Group 3 image: one behind another filter is
stored again as Group 4.
Also from the review: docs/roadmap.md keeps #4335's status line under
this PR's, rather than replacing it; the filters README's tests and the
core.image-filters evidence name the Group 3 layout test; the filters
crate's description names Group 3 and 4 decoding.

- The optimize README, the crate doc and both parity notes say a
halftone or dither, and an image wider than a fax row, isn't averaged
down.
- The README's "Left alone" list is the colour and grey settings'; image
masks, decode arrays and CCITT go to Monochrome Images now. Its
monochrome "Not yet" names an image's own /SMask or /Mask image again
(only images drawn on a page are visited), as the parity note does;
the parity note's row limit is Group 4's.
- docs/architecture.md says CCITT decodes through pdfcraft-filters for
export, redaction and the optimizer, not only the renderer.
- docs/target-app-parity.md no longer lists monochrome downsampling as
missing.

- Redacting a CCITT image went through decoded_image, which undoes the
filters before the fax decoder up to MAX_DECODED, so a Flate bomb in
front of a fax image cost a gigabyte while every other image stops at
twice its raster. Document::decoded_image_within takes a bound, and
redaction gives a fax image's code about a byte per pixel. A fax image
cut short, or behind a bomb, is removed whole; a busy one whose code
is bigger than twice its raster is still cleared.
- Every image is now decoded through decoded_image_within, which reads
/DecodeParms through Document::with_direct_parms: given by reference,
the numbers inside (/Predictor 7 0 R) included. That reading was first
written here and has moved down to #4304. The predictor test now covers
the dictionary, an array's entry and the number itself given by
reference; read without them, the cleared bytes drift off the covered
pixel and the covered sample stays in the copy.

The batch step took Reduce File Size's monochrome settings unchanged, so
`ppi: 600` (or `--ppi 600`) kept colour and grey images at 600 ppi but
halved 600 ppi black-and-white scans to 300. Black-and-white images now
go to the larger of ppi and 300 ppi: a higher ppi keeps their
resolution, and a lower one doesn't take scanned text below 300. The
doc_batch description and docs/cli-batch.md say so.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The PDF Optimizer and Reduce File Size downsampled colour and grey images
but not black-and-white ones. Settings::mono is now MonoSettings {
downsample, target_ppi, above_ppi, compression }, 300 ppi above 450 ppi
and CCITT Group 4 by default (Monochrome Images ▸ Downsample to;
doc_optimize mono: { downsample, ppi, above_ppi, compression }).
A 1-bit image or image mask (no filter, general-purpose filters, or CCITT
fax after any of them) and eight-bit grey of only black and white are averaged by
area: each new pixel takes the sample covering more of it, a tie 0, so a
dark line half a new pixel wide stays. They are stored as Group 4, or as
1-bit Flate when that is smaller; with Retain a resampled image keeps its
kind of compression. Images with a soft mask keep their size.
CCITT decoding moves from Export ▸ Images into pdfcraft-filters
(decode_ccitt, CcittParams, through hayro-ccitt), and
pdfcraft_cos::Document::decoded_image reads a fax image's /DecodeParms
for it (undoing filters before CCITT, such as ASCII85Decode, with any
/DecodeParms given by reference made direct first), so export
and the optimizer share one reader, and Group 4 scans can be
downsampled. A 600 ppi text page went from 79 KB to 40 KB.

docs/architecture.md said every image codec decodes through the
bootstrap renderer; Export ▸ Images decodes CCITT (hayro-ccitt) and JPEG
itself. The progress logs' "(a dithered scan)" sat after "soft mask
counted", as if it described the mask, and so did the
optimize.mono-compression note's "(a dithered scan downsampled to JPEG)".

- A noisy 640 × 800 soft mask under 1200 × 1500 text: resampled to the
image's new size it shrinks only a little, by less than the grey
settings' JPEG adds over the packed image, so packing wins; not
counting the new mask passed every test before.
- The hex-text half of the bomb test also stores eight-bit
black-and-white, which must pack, as its comment says.
- The optimize README, the mono-compression parity note and both
progress logs say the soft mask counts.
- The Copy Image parity note no longer lists CCITT as missing: it
copies through Export's decoder, which reads CCITT now.

Group 4 images (now written by Create PDF and the optimizer) would
otherwise stop exporting: they were reported as "can't be exported
yet". A CCITT fax image (its only filter) is decoded through
hayro-ccitt with its /DecodeParms (K, Columns, Rows, EndOfBlock,
EndOfLine, EncodedByteAlign, BlackIs1), masks included; /Columns has to
be the image's width, so a hostile value can't size the buffers.

- Not only Export ▸ Images refuses a CCITT image until #4335: so does
everything that exports an image through it. Save Image As refuses
it, Copy Image fails, and Word, PowerPoint and HTML export leave the
picture out, with the page not reported. The optimize README and the
mono-compression parity note name them.
- optimize.mono-compression is partial now, so docs/target-app-parity.md
counts it on the table's own measurement: K Optimize and standards 15
shipped and 11 partial of 58 (35.3%), breadth 57.0% (423 + 75 of 808),
mainstream 63.3% (292 + 45 of 497), with a status line and a revision

- Redaction doesn't decode CCITT, so a mark over part of an image the
optimizer stored as Group 4 removes the whole image (nothing leaks),
and Export ▸ Images refuses it. The optimize README and the
mono-compression parity note say so. Later PRs of this stack add both
(#4335 export, #4384 redaction).
- doc_reduce's description, Engine::reduced_bytes and docs/cli-batch.md

optimize row gives the measured counts and no longer lists CCITT as
missing; the M11 milestone row lists it as done.

pdfcraft_filters::encode_g4 encodes packed 1-bit rows as Group 4 (ITU-T
T.6, /K -1) through the fax crate (MIT, already in the tree via tiff),
with rows capped at 32,767 samples so its 16-bit positions can't
overflow; round trips are checked against hayro-ccitt.
The optimizer (Settings::mono, CCITT G4 by default, so Reduce File Size
too) re-encodes a 1-bit image of one colour component, or an image
mask, stored with no filter or general-purpose ones, when that is
smaller as stored. The samples decode to the same bits, so colour
space, decode array and masks stay. PDF Optimizer gets a Monochrome
Images row and doc_optimize a mono option. optimize.mono-compression
goes from planned to partial (JBIG2 and monochrome downsampling not
yet).

* M3: give the kept button release back before the pointer leaves (Wayland)
After a desktop grab the next input on Wayland often brings only
PointerGone. The synthetic release went after it, and a button event
sets egui's pointer position, so the gone pointer came back and hover
stuck at the old place until the pointer moved. The release now goes
before the first PointerGone as well as before the first press; a
release that follows PointerGone is still the kept one and not doubled.

Report generators draw each picture as `q re W n cm Do Q` inside a clip the section shares with
its text. `image_transform_scope` only accepted a scope that contained every active clip, which
none does there, so it fell back to transforming the `Do` alone: the picture grew, but its own
clip stayed at the old size and the enlarged picture showed only through its old box.
When no scope contains every clip, the outermost scope holding only the image is used: it holds
all of the image's private clips, which now move with it, while the outer clip, shared with
other content, stays where it is. A clip shared with a caption inside the same scope still stays
fixed (`cropped_image_resizing_moves_private_clips_and_keeps_shared_ones`). Crop uses the same
scope, so cropping such a picture replaces its own clip instead of nesting a second one.

* M4: Document Properties has a Custom tab for custom properties
Document Properties has a new Custom tab between Fonts and Advanced. It
lists the document's custom properties, and Name and Value fields with
Add, Update and Delete edit the list. Clicking a listed property fills
the fields with it. OK writes the changes through SetInfo in the
existing "Change document properties" step, so one undo reverts them
with the other tabs' changes.
Add is off for an empty value, a name already listed, a name that
check_custom_key refuses (its message is the button's tooltip), and a
name the file already uses for an entry the list leaves out (not text,
only padding, or past the 256 listed). A property already in the file
under a refused name or a name that is not UTF-8 is listed, and Add,
Update and Delete stay off for it, so OK cannot fail on it or write a
different key.
Clearing an /Info entry now removes it when /Info is a dictionary
written directly in the trailer. set_info_entry returned without a
change there, so a delete in the Custom tab, a cleared Description field
and a doc_set_info clear left the entry in the file. It now writes a
copy without the entry as a new indirect /Info.
The engine re-exports check_custom_key and adds Document::has_info
(organize::has_info). set_option("dialog", "custom") opens the tab.
* Contributors: add dotCooCoo (Robert Lee)
* M4: Add in the Custom tab stops at the 256 properties the tab lists
Document Properties > Custom lists at most 256 properties, so a property
added past that was saved but left out of the list when the dialog opened
again. Add is now off once the tab's list or the file's own list holds 256;
a new name goes after the file's entries, so a file with more than 256 keeps
Add off after a Delete as well.
With only --automation-read-root / --automation-write-root set, a path
went straight to std::fs::canonicalize, so a UNC, WebDAV or device path
(`\host\share\x.pdf`, `\.\pipe\x`) was resolved, contacting the host,
before it was refused. `--root` mode already refuses those by name
(`foreign_share`).
`foreign_share` moves into file_access, and `AutomationRoots::check_path`
applies it to the path made absolute (by name, nothing read) before
following links, with the same refusal as any other path outside the
root. A root on a share still accepts that share. `resolve` is split
into `absolute` (empty path, device names, made absolute) and `resolve`
(links followed), so `out\NUL` keeps its own refusal.

Edit::PasteContent pastes an added text box or image copied in the same
document or another, as it was (a text box's style; an image's picture,
turns, flips and crop), as one undo step. A pasted image draws its picture
from the copied object while that is still the picture in the target, else
from an added image there that already holds it (an earlier paste from
another document), else the file is embedded. Document::added_image_file
gives a copied image's picture as a file and honours the copy permission.
pdfcraft_edit::added::paste_rect / paste_place place a paste where the item
was, 18 pt down and to the right past each copy of it on the page (an image
with the same box and transforms counts whichever object holds its
picture), or at a point, kept on the page.
The content_copy tool drives it headlessly, across pages and documents.
