The luminance anomaly detection + LaMa inpainting approach failed because
watermark signal on the matted foreground was too weak (10-15 units vs
threshold of 25). Median filter with kernel=5 effectively removes
semi-transparent watermark text while preserving the stamp structure.
Pipeline is now: median filter (if toggle on) -> BiRefNet matting -> defringe.
No longer requires object-eraser-colorize bundle for watermark removal.
- Fix dispatcher pipe deadlock: drain stdout pipe in a background thread
to prevent blocking when ONNX runtime output exceeds 64KB pipe buffer
- Add 5-minute SSE stall timeout so the UI shows an error instead of
hanging forever when async AI processing stalls
- Guard CPU colorization: skip for images >2MP on CPU and when DDColor
model is not installed, with clear user-facing messages
- Add AVIF decode fallback via ImageMagick for bitstream variants that
Sharp's bundled libheif cannot decode (affects all tools)
HDR and EXR files decoded by ImageMagick can produce 16-bit PNG buffers.
Sharp's CLAHE operation (hist_local) requires VIPS_FORMAT_UCHAR (8-bit).
Check the buffer depth and convert to 8-bit sRGB before processing.
The wrapper used inline-block for tools without overlay children (e.g.
border). CSS maxHeight: 100% on the img inside an inline-block parent
without explicit height does not resolve, so tall images rendered at
natural height and got clipped by overflow: hidden. Unify both code
paths to always use inline-flex + column, where the flex item properly
shrinks within the container's maxHeight constraint.
The find-duplicates tool failed entirely when any uploaded file couldn't
be processed, returning "Duplicate detection failed" or a format-specific
error that aborted the whole batch. With mixed-format uploads (77 files),
this made the tool unusable.
- Skip unprocessable files instead of aborting; return skippedFiles in response
- Switch from fetch() to XHR with upload progress tracking (Uploading X%)
- Add Vite proxy timeout config (5min) to prevent connection drops on large uploads
- Add "Download Grouped" button: ZIP with each duplicate group in its own folder
- Add collapsible skipped-files section in the results UI
- Add 3 integration tests for skip behavior (43 total)
The image element used flex: 1 1 0 (basis 0) inside the inline-flex
preview wrapper, causing it to collapse to zero height whenever a
device frame or watermark overlay was present. Changed to flex: 0 1 auto
so the image uses its intrinsic height and can shrink if needed.
Added regression e2e tests verifying every preset keeps the image
visible, and that adding a watermark does not collapse the image
regardless of whether a frame is active.
setError() in the file store unconditionally set processing to false,
even when called with null to clear a previous error. This meant
setProcessing(true) followed by setError(null) at the start of
processing would immediately kill the processing state, preventing the
progress bar from ever rendering.
Fix setError to only reset processing when there is an actual error.
This also fixes the same latent bug in 10+ other custom tool settings
components that call setProcessing before setError.
The vectorize tool had a custom processing flow that bypassed the
standard useToolProcessor hook -- no progress indication, no server-side
batch, and the Download All ZIP relied on a client-side sequential loop.
Backend: extract core logic into vectorizeBuffer(), register via
registerToolProcessFn() so the /batch endpoint works with p-queue
concurrency and SSE progress events.
Frontend: replace custom fetch loop with useToolProcessor hook and
ProgressCard, giving upload progress, per-file batch status, and
automatic Download All ZIP via the existing tool-page infrastructure.
Also set image/svg+xml MIME type on SVG blobs during batch ZIP
extraction to ensure reliable rendering in <img> tags across browsers.
Adds fileFilter and acceptDescription props to Dropzone so tools can
restrict accepted file types across all entry paths (file picker,
drag-and-drop, paste, single URL import, bulk URL import).
Background images, device frames, custom shadows, and watermark text
were not rendering in the right-pane preview. The preview now updates
in real time for all settings: gradient/solid/image backgrounds, macOS/
Windows/Browser frame chrome, iPhone/MacBook/iPad frame indicators,
custom shadow parameters, and watermark text overlay.
Also fixes a React StrictMode effect-ordering race where the parent
tool-page reset cleared preview state set by the child Settings
component on initial mount.
The stitch route only decoded HEIC via ensureSharpCompat, so exotic
formats (DNG, PSD, TGA, BMP, JXL, HDR, QOI, DDS, ICO, JP2, DPX, etc.)
crashed Sharp at metadata read time, causing "Stitch creation failed".
Add the full CLI decode pipeline (decodeToSharpCompat) matching the
tool-factory pattern, plus SVG sanitization with proper error handling
for each format category.
Replace fetch() with XMLHttpRequest in the frontend to surface upload
progress via onprogress events, and add a progress bar that shows upload
percentage then pulses during server-side stitching.
The X-File-Results header contained raw JSON with non-ASCII characters
from filenames (Chinese, Japanese, etc.), violating RFC 7230. Node.js
threw ERR_INVALID_CHAR on writeHead(). Fixed by wrapping the JSON in
encodeURIComponent() on the backend and decodeURIComponent() on the
frontend, ensuring only ASCII goes into the header while preserving
the original filenames after decoding.
Closes#133
The preview endpoint now returns X-Original-Width/Height headers with
dimensions read from Sharp metadata (or ExifTool for RAW files). The
frontend stores these in FileEntry and the ImageViewer prefers them over
the browser's naturalWidth/naturalHeight, which reflects the resized
preview rather than the original sensor dimensions.
Error from a failed image (e.g. DNG) persisted when navigating to a
previously cached image because the cache path skipped setError(null).
Also pass the original file extension to decodeToSharpCompat so RAW
variants get the correct temp file suffix for ExifTool/ImageMagick.
The compose route only decoded HEIC/HEIF via ensureSharpCompat, causing
EPS, PSD, BMP, RAW, and other exotic formats to fail with
"Processing failed". Now uses the same full format pipeline as the
tool-factory for both base and overlay buffers.
Info panel always read files[0] and stored results in a single useState,
so it never changed when switching images. Now tracks selectedIndex,
auto-fetches on navigation after initial "Read Info" click, caches
results per-index, and aborts stale requests on rapid navigation.
Pass onUrlImport handler through AppLayout to Dropzone so URL-imported
files are loaded on the home page. Add stopPropagation on the modal
overlay to prevent clicks from reaching elements underneath.
- Refactor use-tool-processor and use-pipeline-processor hooks
- Enhance dropzone component with improved UX
- Improve seam carving with better error handling and tests
- Add JXL format encoding support to format-encoders
- Update tool routes for consistent format handling
- Add dropzone unit tests
- Added isImageFile() filter to all drop handlers (dropzone, collage,
file-upload-area) so PDFs and non-image files are rejected on drop.
Previously only the file picker's accept attribute filtered; drag-and-
drop accepted anything.
- Added ppm, pgm, pbm to CLI_DECODED_FORMATS in file-validation.ts.
These formats were missing, causing Sharp metadata checks to fail for
some files during batch validation, which silently dropped them from
results ("File not found in batch results").
- Added integration tests for PBM, PGM, PPM, TIFF, QOI, JP2, SVGZ
single-file processing, plus a test confirming PDF is rejected.
SERVER_PREVIEW_EXTENSIONS was missing TIFF, DDS, DPX, EPS, FITS, JP2,
PBM/PGM/PPM, QOI, SVGZ, CUR, and many RAW variants. The server
already had decoders for all of them but the client never triggered
the preview fetch, so users saw "Preview not available" instead.
Custom SVG showing a landscape image frame with a pencil overlay,
clearly communicating "edit image" instead of the vector pen tool
which read more as Illustrator than Photoshop.
Small bordered buttons with Minus/Plus icons flank the range slider,
allowing single-step quality adjustments. Disabled at min (1) and
max (100) boundaries.
The thumbnail strip expanded beyond the right pane because the flex
section lacked min-w-0, causing a page-level horizontal scrollbar.
Added min-w-0 to both mobile and desktop image area sections.
For non-previewable formats (DDS, TIFF, EXR, PSD, RAW, etc.), show a
file info card with format and size instead of passing the blob URL to
an img tag that fails and shows an infinite "Loading preview..." spinner.
Also changed the ImageViewer error state from a misleading spinner to a
static "Preview not available" message.
AVIF was missing from expandAccept() and every inline accept attribute,
causing the OS file picker to gray out .avif files. Drag-and-drop was
unaffected because it bypasses the accept filter. Added .avif to
dropzone.tsx expandAccept (covers all Dropzone pickers) plus 12 inline
accept strings across tool settings, pages, and file-upload-area.
- Remove duplicate "Files" heading (section header + inline count)
- Space "Show more" and "Clear all" apart on the same row
- Replace bare number input with number + KB/MB dropdown for target
size, defaulting to KB; MB values are converted to KB for the API
- Hide native number input spin buttons for a cleaner look
The before-after slider hardcoded a checkerboard background on the
entire "after" overlay, which filled letterbox/pillarbox space around
non-transparent images. Replaced with a neutral bg-muted/30.
In image-viewer, moved the checkerboard from the outer container
(which included padding) to the img element itself, so it only
shows through transparent pixels rather than the surrounding area.
