The zoom slider's number and range were the natural log of the zoom, so
a screen reader read 0 at 100% and set the zoom in log units. The slider
now runs from 10 to 400 percent on a log scale, and its number is the
percentage its text shows. Reading View reports itself as selected when
the view is Reading View, as the other view buttons do.
The status bar's Fit, Zoom In, Zoom Out, Slide Show, Reading View, Slide
Sorter and Normal buttons and the language name reported no widget info,
the zoom percentage reported only its own text as a label, and the zoom
slider had no name, so a screen reader announced the buttons and the
language without a name. The slide counter and the status message were
painted text with no accessibility node, so a screen reader could not
read them.
Each icon button now reports its tooltip as its name, and the four view
buttons also report whether their view is the one shown. The zoom
percentage is the "Zoom level" button with the percentage as its value,
and the slider is "Zoom" with the percentage as its text value. The
language name is the "Language" button with the language as its value.
The slide counter and the status message are labels with the text they
show.
* fix(pptx): harden import resource budgets, deduplication, and lookup caching
- Chart sidecars (Finding 2): Enforce an import-wide retained byte budget
and cache captured sidecars by chart part to prevent memory amplification.
- Content types cache (Finding 6): Cache parsed [Content_Types].xml defaults
and overrides in Package.ct_cache.
- Text run splitting and font lengths (Finding 8): Bound typeface attribute
lengths and cap paragraph runs to prevent multiplication on text splitting.
- Inner namespace decls (Finding 15): Use HashSet/HashMap indexing and cap
inner declarations to 1,000.
- Slide and notes deduplication (Finding 16): Deduplicate slide paths and
cache parsed notes slide bodies by target.
- Diagram media caching (Finding 22): Cache diagram media payloads in
imp.media_by_part.
- Master slide deduplication (Finding 28): Deduplicate master paths before
loading.
- Layout target deduplication (Finding 30): Deduplicate layout targets
across master slides.
- Chart value axis indexing (Finding 32): Index valAx by axId using a HashMap.
- ChartEx series output budget (Finding 34): Charge series point vectors
against an aggregate output budget and cap series count.
- ChartEx point allocation bounds (Finding 36): Allocate point vectors
only to actual point span bounded by budget rather than declared ptCount.
- SmartArt recursion depth (Finding 38): Limit SmartArt recursion depth to 8.
* fix(pptx): address review feedback on sidecar cache, series budget, and inner decls
* fix(pptx): preserve cached sidecar bytes and non-empty category fallback
- Row 31: Use HashMap for comment author lookup in author_slot
- Row 37: Index preserved parts by ID before resolving graphic frame relationships
- Row 10: Index kept chart parts by normalized path and avoid duplicate payload scans
- Row 39: Update existing relationship parts instead of appending duplicates in PackageOut
* fix(metafile): harden EMF+ parsing, clipping complexity, and memory accounting
- Row 72: Use checked tail slicing in comment header offset calculations
- Row 78: Break FillRects and DrawRects loops early when canvas is full
- Row 75: Pre-check dimensions in decode_compressed before RGBA pixel allocation
- Row 85: Account for EMF+ object table image/path memory against MAX_BYTES
- Row 42: Replace O(N^2) prefix copying in wrap_line with linear measurement
- Row 43 & 54: Share immutable clip regions Arc across placed items and charge canvas regions
- Row 48: Bound text transformation scale and glyph curve geometry in Picture::place and draw_text
- Row 52 & 68: Impose work budget bounds on Sutherland-Hodgman polygon clipping and bitmap masking
* fix(metafile): collapse nested if statement per clippy
Skipped where the receiver type is generic or not evident without a compiler (wrapping_neg, total_cmp, exists, to_vec, as_ref, split_first, Option::into_inner).
