Lataa UVtools 6.2.0

- Layer repair:
- Fixed single-pass island and suction-cup re-detection.
- Fixed the inclusive layer range so the final selected layer is processed.
- Restricted repairs and island detection to the selected range.
- Removed the early return that skipped morphology and empty-layer removal.
- Indexed issues by layer instead of repeatedly scanning all issues.
- Added deterministic Mat disposal and exception-safe attachment locking.
- Fixed attachment of early layers and prevented source-layer modification.
- Improved cancellation handling, validation, progress counts, and all-empty-file handling.
- Prevented repaired islands from being processed again by later stages.
- Operations:
- Audited all operation implementations for correctness, cancellation, native-resource ownership, and avoidable work.
- Invalidated cached validation after settings change, rejected reversed layer ranges, and disposed internally owned
progress state.
- Made native matrix, ROI, cache, and imported-format cleanup deterministic across calibration, import, mesh export,
dynamic-height, arithmetic, dimming, raft, re-height, and redraw operations.
- Reduced multi-layer removal from repeated full-layer shifts to one pass while handling duplicate and invalid indexes
safely.
- Replaced quadratic pattern-image string construction with row builders and avoided oversized pattern tiling.
- Fixed re-height difference accumulation and pixel-corrosion indexing errors.
- Fixed clone, phased-exposure, double-exposure, and timelapse layer placement/counting while avoiding partial commits
on cancellation.
- Made light-bleed compensation deterministic by reading immutable layer snapshots instead of concurrently modified
neighbors.
- Fixed dynamic-lift zero-range calculations, resize fade endpoints, overlapping copy moves, transition progress, and
lift-time calculations.
- Fixed infill wave stepping/Z accumulation, pattern cleanup, and exact pattern repeat sizing.
- Fixed GIF frame counts, zero FPS handling, rotated frame dimensions, save error reporting, and image/heat-map crop
transforms.
- Improved mask ownership and ROI behavior, layer-arithmetic bounds/masking, lithophane sizing, and PCB render reuse.
- Gerber:
- Audited the complete Gerber parser, apertures, macros, and drawing primitives.
- Reworked command tokenization to support multiple commands per line and multiline extended commands without repeated
string concatenation.
- Fixed signed and trailing-zero coordinates, modal D01/D02/D03 operations, relative positioning, duplicate
definitions, and combined G01/G02/G03 commands.
- Added validated single- and multi-quadrant arc interpolation, optional I/J offsets, correctly stroked full circles,
and arc support inside regions.
- Replaced the aperture regex parser with allocation-conscious validated parsing and fixed clipped rectangle flashes
near image boundaries.
- Added ordered macro variable assignments, invariant-culture expression evaluation, malformed-input handling, outline
vertex validation, and rotation around the macro origin for every primitive.
- Consolidated duplicated primitive expression logic and reduced temporary allocations throughout parsing and drawing.
- Capture the coordinate sign so negative plots are placed correctly. by @The-Bootloader (#1133)
- Auto-center the artwork, render it upright, and optionally by @The-Bootloader (#1133)
- Warn when a drill file would be silently ignored. by @The-Bootloader (#1133)
- Add anchors to PCB render
- Excellon:
- Reworked coordinate and tool parsing to handle declared formats, signed and decimal coordinates, zero suppression,
omitted axes, and malformed input without regex allocations or parser exceptions.
- Added incremental coordinates, repeats, routed linear slots, G85 slots, M71/M72 units, and G90/G91 positioning.
- Fixed FILE_FORMAT fractional precision, asymmetric pixel scaling, duplicate tools, stale parser state, and
invariant-culture serialization.
- Added slot rendering and deterministic sizing validation.
- GCode:
- Audited the complete GCode builder, command, and layer-state implementations.
- Fixed invariant-culture output, command equality/hash consistency, line counting, compact command parsing, numeric
validation, LED-off detection, PWM scaling, sync-delay detection, and layer bounds/state resets.
- Fixed relative retract acceleration, zero-valued retract suppression, event arguments, Klipper setup idempotence,
malformed thumbnail handling, and out-of-range layer detection.
- Reduced rebuild work by reusing movement lists, replacing quadratic remaining-time sums with a running total, and
avoiding thumbnail chunk allocations.
- File formats:
- Reduced GCode thumbnail and FlashForge SVGX path-building allocations with bounded stack-backed and sparse DotNext
buffer writers.
- Made FlashForge SVG coordinate serialization culture-invariant.
- Layer compression:
- Preserved sparse, incrementally growing compression streams for large matrices while reducing Zstandard
decompression overhead by decoding directly into the destination matrix.
- Rejected truncated, oversized, and dimension-mismatched LZ4 and Zstandard decompressed data.
- Mesh export:
- Added shared stack-buffered, invariant UTF-8 record formatting across AMF, 3MF, OBJ, OFF, PLY, STL, and WRL exports.
- Replaced repeated dictionary lookups with single-probe vertex-cache access in all indexed mesh exporters.
- Combined binary PLY vertex/face records and STL triangles into one stream write per record without heap allocations.
- Removed per-candidate string allocations from mesh extension lookup and made matching case-insensitive.
- Fixed cropped rotation/flip exports, non-square pixel pitch after quarter-turn rotation, and layer Z placement.
- Made cancellation, temporary writer, and voxel subtraction-matrix cleanup deterministic while preserving the
selected output extension.
- Suggestions:
- Audited every suggestion for validation, cancellation, progress ownership, malformed profile handling, and avoidable
work.
- Fixed bottom-layer target caps, transition-layer zero-step handling and reporting, and exact/stable model corner
placement.
- Corrected bottom/normal limits, clamping, proportional inputs, and light-off-delay handling for wait-before-cure and
wait-after-cure suggestions.
- Removed repeated transition-layer scans, made random anchors allocation-free, and replaced whole-file XML regex
matching with secure streaming profile discovery.
- Advanced image box:
- Fixed zoom-level navigation skipping adjacent levels and failing with an empty level collection
- Corrected centered zoom anchoring and tracker-image sizing when automatic tracker zoom is disabled
- Made pointer panning and selection end reliably when the pointer is released outside the control
- Rejected empty zoom regions and clipped selections safely to image bounds
- Add GetRleBufferInitialCapacity helper to FileFormat for consistent RLE buffer sizing
- Add Goo V5.0, V5.1 and V5.2 support by @AlchMeow (#1129) fixes #1114
- Refactor RLE encode/decode across all file formats to use BufferWriterSlim<byte> instead of List<byte>, reducing
allocations
- Replace List<byte> layer line buffers with MemoryOwner<byte> using ArrayPool for pooled, zero-copy layer
encoding/decoding
- Improve robustness: add bounds checks to RLE decoders, dispose Mat on error, validate ZIP entry sizes
- Optimize FileStreamExtensions read/write methods using BinaryPrimitives and stack-allocated spans
- Fix CTBEncryptedFile.CryptFile to use a shared backing buffer instead of copying
- Fix SL1File swapped BottomLightPWM/LightPWM default values
