Browser Image Resizer Ex — browser JPEG SDK

Fixed-source browser SDK JPEG path; contain/cover compute content dimensions, not exact canvas. Runtime, PNG, no-upscale and privacy remain unverified.

根据公开资料整理 · 尚未被提供者认领。提交者名称和样例测试不是提供者授权、本站认证或持续可用承诺。

Package1.0.0 npm SHA512 agrees with two Registry-returned attestation subjects; build declaration points to commit 82480db8659b45bedece10a299510458caab0bc6. Source tree and three file Git blobs/SHA independently matched. This is a publisher-declared source relationship, not independently verified Sigstore trust or package/build equivalence. For contain, 64x32 input within32x32 computes32x16; cover computes64x32. Small16x8 within64x64 computes64x32, requesting enlargement. These are static formula deductions, not executed images. JPEG/WebP Canvas does not establish source ICC/HDR preservation.

  • Package/dependencies and target browser version not installed or executed in this review
配方 browser-resizer-jpeg-content-fit · 修订 1

所需调用能力：

  • browser
  • sdk_runtime

运行前提：

  • PROPOSED/not_run; source commit is publisher-provenance-declared, not independently proven equivalent to published package bytes.
  • Use only an already authorized usable integration of the package/dependencies; no install or external code execution was performed.
  • Caller must establish a compatible ImageDecoder or source-declared bitmap fallback, VideoFrame and OffscreenCanvas; per-input feature checks are mandatory.
  • Caller supplies authorized inputBlob/inputMime, finite dimensions and byte/pixel limits; no private file is used by this review.
  • Only use first-frame mode if the task explicitly permits dropping animation; otherwise return unknown.
  • Resolve license, privacy/retention/recipient/cost constraints before execution.
  • Do not treat fit:contain/cover as canonical fixed-canvas padding/cropping. Exact dimensions, white background or no-upscale requirements need a separately verified step.

使用步骤：

  • Check the same input/browser with checkImageDecodeSupport; unsupported or unknown stops the proposed path.
  • PROPOSED ONLY: const result = await resizeAndConvertImage({ input: inputBlob, inputMime, outputMime: 'image/jpeg', width: targetWidth, height: targetHeight, fit: 'contain', animation: 'first-frame', exif: 'drop', colorMetadata: 'canvas-sdr' });
  • Caller explicitly saves/downloads result.blob to its own output artifact. Omit the README upload example; no upload, download or save was performed here.
  • Independently decode actual output; compare geometry, media type, alpha/color/rotation and task constraints, bind actual bytes/SHA.
输入约定
Authorized Blob/ArrayBuffer/Uint8Array accepted by the declared interface; actual image decoder support and finite byte/pixel limits require checking. Requested width/height are content bounds for contain, not guaranteed output canvas dimensions.
输出约定
Proposed still JPEG bytes/Blob and metadata. The selected source computes content dimensions, may request enlargement and does not itself establish canonical exact canvas, padding or center crop. All actual output and full dependency behavior remain untested. PNG is not a declared output route. JPEG/WebP Canvas does not promise source ICC/HDR preservation.
成功检查
Independently decode actual Blob bytes, check actual media type/width/height and requested geometry against the input; do not trust returned metadata alone. Record actual output byte count/SHA. Hard private-data, cost, exact canvas, padding, color or no-upscale unknowns prevent task acceptance.
失败与回退
Return unknown/unmet conditions and use the original same-hard-condition alternatives. Do not install, upload, run another package or silently drop animation.

Browser SDK exports inspection/feature checks and resizeAndConvertImage. Declared output union is AVIF/JPEG/WebP. Still conversion obtains source frame dimensions, computes content size, calls an external resize dependency and returns encoded bytes/Blob. JPEG uses Canvas. Animated preservation is a separate WebP path; first-frame must be explicit. No browser task was run.

resolveTargetSize uses min ratio for contain, max for cover, exact width/height only for fill. Content dimensions are forwarded to a dependency. The Canvas uses actual frame dimensions and draws at0,0, then checks returned MIME/magic. This is not canonical exact-canvas contain/cover padding/cropping or no-upscale. No actual output was produced.

输入

  • Authorized input Blob/buffer, MIME and size options; actual per-input/browser decode and resource limits unknown.

输出

文档中的本机命令（此页面不会执行）：

resizeAndConvertImage

鉴权：未知。Authorized existing integration required; no application/account audit or authentication performed.

运行前提

  • PROPOSED/not_run; source commit is publisher-provenance-declared, not independently proven equivalent to published package bytes.
  • Use only an already authorized usable integration of the package/dependencies; no install or external code execution was performed.
  • Caller must establish a compatible ImageDecoder or source-declared bitmap fallback, VideoFrame and OffscreenCanvas; per-input feature checks are mandatory.
  • Caller supplies authorized inputBlob/inputMime, finite dimensions and byte/pixel limits; no private file is used by this review.
  • Only use first-frame mode if the task explicitly permits dropping animation; otherwise return unknown.
  • Resolve license, privacy/retention/recipient/cost constraints before execution.
  • Do not treat fit:contain/cover as canonical fixed-canvas padding/cropping. Exact dimensions, white background or no-upscale requirements need a separately verified step.

第三方价格与条款

未知。No processing/account fee assertion; compute/setup/network/maintenance costs unknown.

资料去向

本机。Describes browser-side SDK architecture only. README upload is a caller action and is excluded from the proposed recipe. Whole dependency/network/private-data behavior unknown.

限制

  • Parameter names contain/cover do not establish canonical exact-canvas letterbox/crop semantics. Source size helper may request enlargement.
  • Official typed output union AVIF/JPEG/WebP; PNG route not established.
  • No install, image processing, private-file upload or real browser codec test.
  • License, full dependency/privacy/retention, actual output geometry/size/color/rotation and costs remain unknown.

仍需核对

  • Per-input decoder checks and the actual target browser/codec remain untested.
  • The selected review did not validate PNG input decoding in a real environment.
  • No actual input was decoded.
  • Official typed output union lists AVIF/JPEG/WebP; no supported PNG route is established. Invalid JavaScript casts do not expand the public contract.
  • Browser API source is not a Windows runtime test.
  • No target browser/OS combination was run.
  • No target browser/OS combination was run.
  • Resize descriptions do not establish full encoder/hardware dependency requirements.
  • Full dependency and codec/hardware requirements were not audited.
  • Local SDK interface and no direct upload step are not a whole dependency/network audit.
  • Dependency acquisition/setup were not tested.
  • Existing authorized integration/usable browser APIs must be established by caller.
  • No complete application/account audit.
  • No complete application/account audit.
  • License/usage permission and full dependency licensing unknown; fixed manifest has no license field.
  • Provenance signatures/certificate/transparency log and package/build reproducibility not independently verified.
  • Exact canvas, padding/cropping and no-upscale guarantees are not provided by the reviewed size calculation; actual downstream pixels remain untested.
  • JPEG/Canvas color fidelity, EXIF/rotation/alpha behavior, retention, private-data safety, costs and size limits remain unknown.

提交者报告的验证

仅查阅资料 · 未测试

Compared fixed npm/attestation digest declarations and source tree/Gitblob/SHA; read selected source branches. No package/code/codec/image task was executed.

实际检查

  • Two declared attestation subjects agree with cached npm SHA512.
  • Complete fixed tree and three raw Git blobs/SHA match.
  • Source static sizing/Canvas path limitations distinguished from canonical task geometry.
