| # SDOCX Compatibility Corpus |
|
|
| This dataset contains paired Samsung Notes `.sdocx` documents and reference PDF exports for parser, renderer, and visual-regression testing. Each pair has a numeric ID and descriptive name recorded below. |
|
|
| The `.sdocx` file is the source fixture. The matching PDF is the expected visible result exported from Samsung Notes; it is a visual reference, not a byte-for-byte rendering requirement. |
|

|
|
| The `01-basic-formatting` source archive stores six page records, while its reference PDF contains five visible pages. The `03-image-placement` archive contains four page records and one embedded 451 × 300 RGB PNG, while its reference PDF contains three visible pages. Consumers should preserve stored structure separately from visible-page rendering semantics. |
|
|
| ## Intended use |
|
|
| - Check whether an SDOCX parser can load real Samsung Notes archives safely. |
| - Compare rendered output with the corresponding Samsung Notes PDF. |
| - Build focused compatibility tests for document structure, text, tables, links, code blocks, and styling. |
| - Track renderer changes with page-level visual diffs. |
|
|
| When comparing output, normalize page size and rasterization settings first. Font substitution, antialiasing, and PDF renderer differences can create harmless pixel-level changes. |
|
|
| ## Limitations |
|
|
| This is an early, synthetic compatibility corpus with four fixtures. It is not representative of every Samsung Notes version, device, font, pen type, embedded-media type, encrypted document, or malformed archive. A successful result on this dataset does not imply full SDOCX compatibility. |
|
|
| The SDOCX format is proprietary. This dataset documents observed behavior and does not provide or claim an official format specification. |
